Drought Information Statement
National Weather Service Reno NV
Feb 17 2015
1/ Nevada and Eastern California drought disaster designations...As of February 4 2015...All counties in California along the Nevada border were designated as primary natural drought disaster areas by the U.S. Department of Agriculture. In Nevada the following counties were designated as primary natural disaster areas due to damages and losses caused by the drought conditions: Carson City...Churchill... Clark...Douglas...Esmeralda...Humboldt...Lander...Lyon...Mineral... Nye...Pershing and Washoe. Farmers and ranchers in Elko... Eureka...Lincoln...Storey and White Pine counties also qualify for natural disaster assistance as these counties were designated contiguous natural disaster areas. From USDA. A second emergency drought proclamation was made by Gov. Jerry Brown of California in April 2014 that would ease some environmental protections and make it easier to transfer water to farmers. The executive order also shortens the application process for farmers seeking irrigation water and hastens the process for cities wanting to upgrade or expand water systems. Additionally, home owners associations may not fine residents who choose not to water their lawns. The order also makes Cal Fire and other emergency responders exempt from competitive bidding rules when buying equipment to fight fires or reduce fire risk. From Reuters, NY, April 25, 2014. In late November 2014 the U.S. Bureau of Reclamation announced the awarding of 9.2 Billion dollars to 131 research groups across the Western U.S. This funding is for developing ideas to ensure a reliable and sustainable water supply. Partners in this effort include federal and non-federal agencies...Research centers and laboratories...And universities and private companies. From Houston, TX, Chronicle, Nov 20, 2014. See www.usda.gov/drought /in lower case/ for more information on drought disaster declarations and assistance.
2/ Current drought intensity in Nevada and Eastern California... The U.S. Drought Monitor /droughtmonitor.unl.edu/ is updated weekly by the national drought mitigation center. It is a synthesis of multiple drought indices and impacts that represents a consensus of scientists in many federal...State and local agencies...As well as those in private industry. The drought monitor is used by the USDA to determine drought severity...To declare drought disaster and is the mechanism used to provide aid to the agricultural community. It is also the primary tool used by the Nevada departments of emergency management and water resources to respond to and provide assistance for drought and mitigate drought impacts through their drought response plan. As of February 10 2015...The U.S. Drought Monitor classified most of Western...Central and Southern Nevada and Eastern California as in severe drought /level 2 of 4 levels of drought/ or greater. A large part of far Eastern Nevada saw improvement in its drought status as a result of monsoon rains that fell from late July through the middle of September...And precipitation that fell in October and December. The area of extreme to exceptional drought in Nevada included all or portions of the following counties... Carson City... Churchill... Douglas... Elko... Esmeralda... Eureka... Humboldt... Lander... Lyon... Mineral... Nye... Pershing... Storey and Washoe. The hardest hit areas of drought...Where it was classified as exceptional... Are much of Pershing and Mineral counties...A small part of Western Lander County...All of storey County and Carson City...Along with Douglas and Lyon counties...And the southern half of Washoe County in Nevada. The areas least affected by drought in Nevada included Central and Eastern Elko County...White Pine County...Far Northeast Nye County and much of Lincoln and Clark counties which were classified as in moderate drought /drought level 1/.
Drought severity was classified as extreme or exceptional for all California counties bordering Nevada from Modoc County south to Western San Bernardino County. The area of exceptional drought /drought level 4/ included much of Lassen County... Far Eastern Plumas... Sierra... Nevada... Placer and Eldorado Counties...And all of Alpine County. The northern 2/3rds of Mono County and the Sierra Crest portion of Inyo County were also classified as having exceptional drought. The remainder of Mono County...Most of Inyo County and Far Western San Bernardino County were classified as having extreme drought. Southeast Inyo County and much of the remainder of San Bernardino County were classified as having severe drought...Except for those areas of San Bernardino County bordering the Colorado River which was classified as having abnormally dry conditions to moderate drought.
3/ Synopsis... Below to much below normal precipitation has occurred over most of Eastern California and Nevada since October 2011. Small parts of Eastern and Western Nevada have experienced near normal to slightly above normal precipitation during this time...As well as areas along the Colorado River in extreme southeast California. During the calendar year 2014...Precipitation was below normal for central and southern Nevada and much of west central Nevada...As well as most of Eastern California from the Tahoe Basin south. Parts of far Western Nevada...Alpine County in California...Northeast Nevada...Far Northwest Nevada...Northeast California...And far southeast California near the Colorado River received above normal precipitation for the year. Above average precipitation across northern and Eastern Nevada in May of 2014 and again during the summer monsoon from July through early September 2014 brought East Central Nevada to above normal for the year. Heavy convective rain in May 2014 and again in July and August 2014 brought a small part of Western Nevada...Mostly Mineral County...to above average. These convective rains along with wet periods during November and December 2014 brought much of Northeast California and far Northwest Nevada to above normal for the past year. A wet pacific storm brought moderate to heavy rain across Northeast California in early February 2015...Pushing the area above normal for the water year 2015...But snow levels were quite high in this storm. This limited the extent of additional snow cover...An important source of water during the irrigation season. /See:http://www.wrcc.dri.edu/wwdt/archive.php?Folder=pon6per / the driest areas...Those that had less than 70 percent of normal precipitation since February 2014...Include parts of Mono...Inyo... San Bernardino...Placer and Eldorado counties in California. In Nevada...Extreme southern Washoe County along with parts of Carson City...Douglas County...Storey County...Lyon County...Southern Mineral County...Esmeralda County...Southern Nye County...Most of Clark and Lincoln counties and parts of central Lander and Eureka counties received less than 80 percent of their average precipitation since February 2014. The areas of above normal precipitation during this period of time included parts of Lassen County and the surprise valley in California and Alpine and far northern mono counties in Eastern California...And far Eastern San Bernardino County in southeast California. Far northern Washoe County...Northern and central Mineral County...Northern Humboldt County...Far Western Pershing County...Much of central and Eastern Elko County and north central White Pine County in Nevada were all above normal over the last 12 months.
4/ Drought impacts... The winter of 2013/14 was the third straight winter with below normal precipitation for much of the area. While fall 2014 and early February 2015 brought some relief...Much of the area has seen below average precipitation since October 2011. The following impacts...While not all inclusive...Represent some of the most impactful effects of the continuing drought on the region over the last year.
- A/ ranching... A Nevada state legislative bill /sb 134/ to allow Nevada livestock owners in drought stricken areas emergency access to water was passed by the Nevada senate and signed into law by the governor in may 2013. It created an emergency water permitting process which is available when state or federal officials declare a drought emergency. Ranchers should contact the Nevada department of water resources for more information at http://water.Nv.Gov/ or by phone at 775-684-2800. In May 2014 the BLM office in Battle Mountain requested nine ranchers with grazing rights on the Argenta Allotment to rest sensitive areas during the summer of 2014 to allow the range to recover from three years of extreme drought. The allotment covered 365,000 acres south of Battle Mountain. The range had suffered damage and needed time to recover to remain a productive rangeland for livestock. From Elko, NV Daily Free Press, May 6, 2014. As of May 29, 2014 the blm agreed to allow the affected ranchers continued grazing rights in the disputed areas as long as lingering drought conditions did not worsen. From Las Vegas, NV sun. May 29, 2014. On July 23, 2014 the Battle Mountain BLM office once again announced the closure of some of the argenta grazing allotments. The BLM cited data that indicated drought triggers had been met requiring removal of cattle from nine segments of the allotment. From Elko, NV Daily Free Press, July 24, 2014. The agricultural act of 2014 allowed livestock producers who had suffered losses as far back as October of 2011 to apply for assistance. A livestock indemnity program may assist producers who lost stock due to adverse weather. Officials with the USDA said as much as $2-3 billion could be paid for past disasters. Applications had to be received by Jan 1, 2015. From Lincoln, NE, Journal Star, April 17, 2014. Due to the drought disaster designation throughout all counties in the region...Ranchers have been able to obtain various financial and tax relief solutions through USDA. See the USDA farm services agency website for details /www.fsa.usda.gov.
- B/ agriculture... Farmers did not receive a full allocation of water in the summer of 2013 and most received little if any of their allocations for the summer of 2014. Humboldt River Basin... No deliveries were made for the 2014 irrigation season on the lower Humboldt below rye patch reservoir. Most farmers and ranchers in the lower Humboldt Basin do not supplement surface water with ground water. Rye patch reservoir remains near 5 percent of capacity. The five counties of the Humboldt river water authority /Humboldt...Elko...Eureka...Lander and Pershing/ have reinforced the state of Nevada action declaring a drought resolution that would encourage Nevada and federal agencies to coordinate to best handle drought impacts in the hard hit areas. Walker river basin... Initial storage water allocations for the walker river basin for the 2014 irrigation season were announced on march 14 2014. Well below average storage in Bridgeport Reservoir and Topaz Lake along with a below average snow pack in the upper portions of the Walker Basin resulted in storage allocations set at 9.5 Percent on the east walker river and 1.33 Percent on the west walker river. The Walker River irrigation district encouraged water rights holders to take their water as soon as possible rather than wait later in the season. Reno, NV Gazette-Journal, March 15, 2014. There was concern that the storage allocations could evaporate in the reservoirs before being served. In a conversation with the Walker River watermaster in Yerington it was noted that surface water allocations would be determined on a daily basis during the 2014 irrigation season. Additional communication with the Walker River watermaster in early June indicated there were no deliveries from the East Walker River...And the west walker delivered only 5 days worth of decreed water to 1865 water rights holders. The watermaster also indicated that wells were being redrilled in the basin and pumping operations were very high in June. In late August a Cocorahs observer in yerington reported alfalfa fields left dry with groundwater used to irrigate only a small number of fields. The walker River was at a trickle with no water for irrigation. Levels in domestic wells were dropping as were levels in irrigation wells. In early February the Nevada state engineer issued an order that requires a 50 percent mandatory reduction of ground water that may be pumped for the 2015 irrigation season in the Smith and Mason Valleys of the Walker River Basin. The objectives of the order are to protect existing water rights and wells...Protect the physical integrity of the aquifer and to protect the long term water supply. From ThisisReno.com, Feb 4, 2015. Carson River Basin... On May 9 2014 the Truckee-Carson Irrigation District /TCID/ announced a plan to cut allotments for the 2014 irrigation season to 45 percent of normal. This plan still needed approval of their board members...But the announcement was made early to allow farmers in and around the Fallon area who depend on water from tcid to make plans to cut their water usage. From KTRVN and KRVN, Reno, NV. May 9, 2014. Truckee River Basin... As of July 30, 2014 releases from boca reservoir were cut drastically. This reduced flows on the Truckee river by about half. Lake Tahoe dropped below its natural rim late on October 15, 2014 for the first time since 2009. This meant only a small trickle of water was escaping lake Tahoe and by October 17 virtually no flow was leaving lake Tahoe. The reduction in flows meant that floriston rates were not met from late summer into the early fall. Due to the drought disaster designation throughout all counties in the region...Farmers may be able to obtain various forms of financial and tax relief through USDA. See the USDA farm services agency website for details /www.fsa.usda.gov Susan River Basin... In early May in a discussion with the Honey Lake Basin watermaster it was learned that surface water deliveries from the Susan River had ended as reservoirs were empty at that time. The only available water to ranchers was ground water. In early June the USDA received feedback from the Cattlemen’s Association in Lassen County that conditions were the same if not worse than 2012 with creeks and streams drying up and no run off from snowmelt. Farmers and ranchers across California were offered 20 million dollars in aid by the USDA for water conservation projects. These included such projects as updating irrigation methods...Preventing erosion from unplanted fields and determining better methods to water livestock. Farmers who receive less than 15 percent of their water allocations will be given priority. From Sacramento, CA, Bee, Feb 15, 2014. Colorado River Basin... The department of the interior and four municipal water providers in Arizona, California, Nevada and Colorado have contributed 11 million dollars to promote water conservation in the Colorado River basin. They will take part in a pilot program to reduce water demand by farmers, cities and industries. From Las Vegas, NV, Sun, July 31, 2014.
- C/ fire danger... As of February 15...Fire danger was rated as low to moderate over Northeast California and Northwest Nevada. The fire danger ranged from moderate to high from the southern sierra into southeast California and across southern Nevada. Fire danger classification is updated daily. See http://www.wfas.net/images/firedanger/fd_class.png for current conditions. As of February 1 2015...The NIFC fire potential forecast for the region was near normal for February through May over all of Nevada and Eastern California. See U.S. Forest Service Wildland Fire Assessment System website for details...http://www.predictiveservices.nifc.gov/outlooks/monthly_ seasonal_outlook.pdf. A wind driven wild fire that reached over 7000 acres destroyed 40 residences in two communities along the Inyo/Mono County border in early February. The ongoing drought conditions in the area created extremely dry brush that fueled the flames and pushed up the slopes to the snow line around 8000 feet. From San Francisco, CA, Chronicle, Feb 9, 2015.
- D/ fisheries... Low flows continue to impact fisheries around the region. Nevada Division of Fish and Wildlife reported high impacts to fish in Lahonton...Rye patch...And other reservoirs that were severely drawn down. The Carson...Walker...Humboldt and several other rivers and streams throughout the region have also been impacted. Wildlife officials expressed concern that periods of high temperatures combined with low water levels could lead to a lessening of dissolved oxygen in lakes and reservoirs and result in die offs. Die offs were expected in Wildhorse and Willow Creek Reservoirs in Elko County...And for the second year in a row the state lifted limits in those two reservoirs to allow more fish to be removed before conditions became unsurvivable. From Reno, NV, Gazette-Journal, Jun 24, 2014. Fish kills occurred at Topaz Lake in southern Douglas County and at Squaw Creek Reservoir north of Gerlach this year. Meanwhile... Drought and irrigation demands lowered the level of the onion valley reservoir in the pine forest range of Humboldt County, NV...Wiping out the trout fishery. From Las Vegas, NV, Sun, Oct 9, 2014. Nevada Department of Wildlife has also reported dead fish showing up at Washoe Lake since October of 2014 due to the dry conditions. Some residents have expressed concern...But NDOW added they are not concerned about toxins in the lake...Saying it’s part of a natural cycle due to the drought. Less water means fewer fish. From KOLO-TV News 8, Reno, NV, Dec 29, 2014. The drought conditions have once again prompted Nevada Department of Wildlife officials to restock the Truckee river early this year. Around 7000 rainbow trout are scheduled to be planted in the Truckee River in the middle of February. Additional stocking will take place in the Truckee River, Topaz Lake, Marlette Lake, Spooner Lake, Hobart Lake and urban ponds around the Reno-Carson City area between late March and October. This marks the second year in a row drought conditions and anticipated low flows on the Truckee have prompted early stocking of the river. From Reno, NV, Gazette-Journal, Feb 12, 2015. See the Nevada Department of Wildlife website /http://www.ndow.org/ for fishing condition information in Nevada. For California fishing information...See the California Department of Fish and Wildlife website /http://www.wildlife.ca.gov/
- e/ vegetation and wildlife... Drought conditions resulted in bears moving into more urbanized areas this year in search of food. As of early November 2014 Nevada wildlife officials had received well over 500 complaints regarding bears for the year so far...Well short of the record 1500 complaints received in 2007...Another drought year...But well above normal. Of approximately 70 conflict bears handled by NDOW...Many have been found away from their normal high-mountain habitat. Included in these calls were 29 bears in the Lake Tahoe communities of Nevada...14 In Reno...9 In Carson City and 5 in Minden-Gardnerville. There was even one report of a bear in the Spanish Springs area of Northeast Sparks...Well away from the mountains. From Reno, NV, Gazette-Journal, nov 9, 2014. A deterioration of water quality in two Reno city parks...Where lakes had not received water from the Truckee River since early August...Was blamed for the death of numerous ducks. Twenty-four ducks were found dead at Virginia Lakes while roughly the same number had died at Paradise Park. Avian botulism was thought to be the cause. From Reno, NV, Gazette-Journal, Aug 26, 2014. In an update...Laboratory tests confirmed avian botulism as the cause of death of ducks in Reno in late august in two drought depleted lakes. From Reno, NV, Gazette-Journal, Sep 8, 2014. The dry conditions also affected the number of ducks stopping over during their migration this fall. The lack of water in areas where the ducks would normally stop resulted in a lessening of the number of ducks and a decrease in hunting opportunities. From Reno, NV, Gazette-Journal, Oct 29, 2014.
- F/ ground water... The Carson Water Subconservancy Sistrict has reported that many farms in the watershed pumped more ground water during the 2014 irrigation season. In South Lake Tahoe three wells were affected by contaminants as less groundwater was available to dilute the contaminants. Two of the wells contained the contaminant pce. All three wells were shut down...Leaving barely enough water for 950 homes. From Capital Public Radio, Sacramento, CA, Nov 12, 2014.
- G/ urban area drought impacts... Reno/Sparks... The Truckee Meadows Water Authority /TMWA/ serving the Reno and Sparks NV area...Asked residents to reduce their water usage by 10 percent in early August...But no mandatory conservation measures were enacted. In November 2014 TMWA announced the 10 percent goal was not met...But voluntary efforts led to a reduction in usage of 7.5 Percent. TMWA used 18 percent of its drought reserves...Mainly from Donner Lake...And was not forced to tap its largest reserve... Independence Lake. Water usage was expected to drop through the fall and winter with the end of irrigation season...TMWA stated. From Reno, NV. Gazette-Journal, Nov 6, 2014. See www.tmwa.com/conservation for details. The Truckee Meadows Power Authority shut down three hydropower plants in late July as water levels fell too low to continue operating. From KOLO-TV News 8, Reno, NV, July 30, 2014. Las vegas... Both the Southern Nevada Water Authority /SNWA/ and the Las Vegas valley water district /lvvwd/ enacted winter watering restrictions november 1st. Landscape watering is allowed on only one day each week. These restrictions will remain in effect through February 28. See www.snwa.com or www.lvvwd.com for details. SNWA approved a project to extend the life of an old shallow intake pipe and pumping station that the Las Vegas community now uses to draw about 90 percent of its drinking water supply from Lake Mead. Officials declared the project to be an emergency in September of 2013 because the U.S. Bureau of Reclamation announced in August 2013 the inflow to Lake Mead during 2014 would be the smallest annual water delivery in the lake’s history. From Las Vegas, NV, Review-Journal, Sept. 26, 2013. The emergency drought declaration made by California Gov. Jerry Brown on Jan. 17, 2014 allows the state of California to take more water from Lake Mead. This could lead to water restrictions in the Las Vegas valley by 2015. Once the lake drops to a level of 1075 feet SNWA can declare a water shortage. To alleviate the problem of a lower lake level...SNWA is constructing a third intake pipe that sits deeper in Lake Mead. If this intake is not completed prior to the first intake becoming obsolete...Officials say southern Nevada could face significant problems. Power generation could also be affected by the lowering lake level. From KLAS, Las Vegas, NV, Jan. 26, 2014. On December 10, 2014 SNWA announced a 3 mile long tunnel had been completed to the third intake “straw” on Lake Mead. Construction had begun in 2008 to provide a buffer against drought. There are also plans to build a new 650 million dollar pumping station to provide water even if the lake falls below an elevation of 1000 feet. From Las Vegas, NV, Sun, Dec. 10, 2014. Central and Southern Sierra Crest counties... Pacific gas and electric company held back water during the spring of 2014 and generated less hydropower with the expectation the water would be used for production in summer when demand would be higher. The California Energy Commission estimated production in the Sierra in 2014 would be roughly half what it was in 2010, a normal year. From Fresno, CA, Bee, August 4, 2014. Truckee... The city of Truckee imposed mandatory stage 2 drought restrictions on August 12, 2014. This limited watering to two days per week. North Tahoe... The north Tahoe Public Utility District also imposed stage 2 drought restrictions on August 15, 2014. Prohibitions included no washing of paved surfaces, no irrigating between 11 am and 6 pm, no filling or refilling of swimming pools and no use of potable water for dust control. Tahoe City... Stage 2 drought restrictions were announced on July 25, 2014, restricting outdoor spray irrigation, imposing day of the week watering based on addresses and restricting bars and restaurants to the serving of water only upon request. South Lake Tahoe... Stage 1 mandatory restrictions were also enacted. Restrictions included: no irrigating of undeveloped property, no water in restaurants unless requested and no washing of paved surfaces.
- H/ tourism and recreation impacts... Low flows on the Truckee River prompted the Truckee River Rafting Company and Irie Rafting Company to announce they would allow no rafting in August...Normally one of their most profitable months. The Sand Harbor Boat Ramp on lake Tahoe’s Northeast shore has closed for the summer. This ramp normally remains open all year. From KTVN News 2, Reno, NV, Jul 27, 2014. The lower level of Lake Tahoe also exposed obstacles that were nearer to the water surface and caused damaged to boat propellers. The general manager of the Tahoe City Marina noted the lake had become too shallow for some sailboats to enter the marina. From Tahoe City, CA, Tribune, July 22, 2014. On January 19, 2015 the Tahoe donner cross country ski area announced it would temporarily close because of limited snow and icy conditions. The ski area plans to reopen when a greater snowpack allows. From Tahoe City, CA, Tribune, Jan 19, 2015. In late January 2015 Homewood Mountain Resort announced it would place upper mountain operations on hold. In early February the resort...On the west shore of Lake Tahoe...Announced it would suspend all operations until snow conditions improved. From Tahoe City, CA, Tribune, Feb 4, 2015. The US Forest Service in the Lake Tahoe Basin has asked snowmobile users to avoid bare dirt and patchy snow...And not to ride across streams or over small trees and brush. This request was prompted by the poor snow conditions in the Lake Tahoe Basin and to protect resources that could be damaged by operating snowmobiles on too little snow. From Capital Public Radio, Sacramento, CA, Feb 5, 2015.

6/ Long range weather outlook for Nevada and Eastern California... From the National Weather Service Climate Prediction Center... The outlook for the months of March through May is for above normal temperatures for all of Nevada and Eastern California. The precipitation outlook is for above normal precipitation across the southern 2/3rds of Nevada...Generally south of Interstate 80...The Sierra Nevada mountains of California south of highway 50...And southeast California. The remainder of the area is forecast to have equal chances of above...Near and below normal precipitation.
Next issuance date... This drought statement will be updated in mid March.
