By Max Stevenson; Idaho Statesman Beneath the high desert of the Treasure Valley lies a complex aquifer. Below-ground water levels are changing in response to the shifting uses of land at ground level. Urbanization has replaced farm fields with subdivisions and commercial centers, reducing how much water flows into the ground through irrigation. These rapid changes have begun to lower the Boise area’s water table, causing problems for some rural homes that rely on well water. Dennis Owlsey, a hydrogeologist with the Idaho Department of Water Resources, stood before a screen one day this summer, looking at a map showing the conversion of farmland to development. “You don’t need to run any fancy statistics just to visually see it’s a major problem,” Owlsey said. ‘Flood irrigation’ adds to groundwater Western…
By Bill Schaefer; Capital Press POCATELLO, Idaho — A diverse group of 13 water users met Sept. 13 to review the 2015 agreement between groundwater and surface water users and its impact on the Eastern Snake Plain Aquifer. The group's job is to draft amendments to the agreement or a new management plan that will help restore the aquifer without harming senior or junior water rights holders. IDWR Director Gary Spackman tasked James Cefalo, the IDWR eastern regional manager, with organizing the advisory committee. In 2016, Spackman designated the aquifer as a Ground Water Management Area. A GWMA designates all or part of a groundwater basin that may be approaching conditions of a Critical Ground Water Area. Idaho aquifer Under a GWMA, applications for new water appropriations may be approved…
By Shaun Goodwin; Idaho Statesman Boiseans have been spoiled the past few days with temperatures in the 80s and no rain, but good things never last forever. Starting Thursday and continuing through Saturday afternoon, about half an inch of rain is expected to fall in the city, and high temperatures will drop to the mid-60s over the weekend, according to the National Weather Service. “We’re going to be kind of unstable (Thursday) and we could be seeing some thunderstorms,” Chuck Redman, a meteorologist in Boise, told the Idaho Statesman. “And then the main low-pressure system itself, the main weather maker, is going to be coming over us on Friday.” Redman expects a consistent and dreary pattern for Boise, while the mountains north of the Treasure Valley will be subject to…
By Mia Maldonado; Idaho Capital Sun The U.S. Geological Survey announced it will soon begin measuring groundwater levels across southern Idaho, according to a Monday press release. Survey employees working with the Idaho Department of Water Resources and the Bureau of Reclamation will measure groundwater levels in more than 1,400 private and public wells in the eastern Snake River Plain between April 3-14. The region’s aquifer is the area’s primary source of drinking water and irrigation for 1 million acres of farmland in the state aquaculture industry, according to the news release. The collected data will help water experts understand the status of the aquifer ahead of the irrigation season, and the IDWR will use the data to improve its computer model of the aquifer. Water technicians collect aquifer measurements…
By Seth Oliver; Guest Contributor for the Coeur d'Alene Press The fifth edition of the Spokane Valley-Rathdrum Prairie Aquifer (SVRPA) Atlas is set to be printed and available early this spring. Seen here: A depiction of the Spokane Valley-Rathdrum Prairie Aquifer. The fifth edition of the Spokane Valley-Rathdrum Prairie Aquifer (SVRPA) Atlas is set to be printed and available early this spring. The SVRPA Atlas is a collaborative effort of groundwater professionals, water quality experts, environmental specialists and science educators from Washington and Idaho to disseminate the most up-to-date information on our region’s sole source of drinking water. The SVRPA Atlas is the culmination of hard work among more than 30 individuals over the past 20 years to consolidate some of the most important information regarding our region’s aquifer, including…
Capital Press The Idaho Water Resource Board’s Milepost 31 Eastern Snake Plain Aquifer recharge site. Projects adding to recharge capacity are among those funded by the board Nov. 18. Boosting aquifer levels and improving irrigation delivery efficiency are the focus of Idaho Water Resource Board moves to financially support several projects in the state’s south-central and southeast regions. The board Nov. 18 approved a $14.1 million loan to Raft River Recharge Group. Plans call for building a pump station on the Snake River, a 13-mile pipeline, and recharge basins to add water to a declining aquifer in a state-designated critical groundwater management area. The declining aquifer levels are a key factor in intermittent surface flows on the Raft River, a Snake tributary. Most farmers are now pumping groundwater for irrigation,…
By Anthony Kuipers; Moscow-Pullman Daily News The Palouse Basin Aquifer Committee presented its report on alternative water sources to the Moscow City Council on Tuesday in an effort to inform city leaders about ways to slow the aquifer’s decline. PBAC hired Alta Science and Engineering Inc. as a consultant to analyze the four alternatives. The recommended alternative is to divert water from the South Fork of the Palouse River in Pullman eight months out of the year, and divert water from Moscow’s Paradise Creek four months out of the year. It was the option that scored the highest based on criteria that includes cost and reliability. During a July PBAC meeting, Alta’s water resources division manager Robin Nimmer said this option had the least expensive capital cost of $73 million…
Kerri Treinen U.S. Geological Survey, Idaho National Laboratory Project Office presenting "An Update of hydrologic Conditions and Distribution of Selected Constituents in Water, Eastern Snake River Plain Aquifer, Idaho National Laboratory, Idaho" Tuesday Aug. 30, 2022 11:30-12:20 MT (10:30-11:20 Pacific)
Moscow-Pullman Daily News The Palouse Basin Aquifer Committee is currently evaluating additional water sources for Latah and Whitman counties. Robin Nimmer, a senior hydrologist in the Water Resources Division at Alta Science and Engineering, spoke at the League of Women Voters of Moscow speaker forum Wednesday about how to ensure a lasting supply of water for the communities. "We've known about water level decline for a very long time," she said. "The wells aren't flowing anymore and we actually have data that shows us the water level is declining in our aquifer." Nimmer has recently been working with the Palouse Basin Aquifer Committee, which was formed in the 1980s, to evaluate alternative water sources for the region. The committee's mission since its start has been to plan for continued use…
By Andrew Guckes; Idaho Mountain Express On Monday Ketchum became the final city in the Wood River Valley to approve a term sheet proposed by the Idaho Department of Water Resources that requires each party to put forth funds to combat water shortages and help preserve groundwater aquifers in the area. The deal includes Sun Valley Co. and the Sun Valley Water and Sewer District, in addition to the cities of Ketchum, Sun Valley, Hailey and Bellevue. For the next three years, each of those parties will contribute $10 per acre-foot of groundwater diversions to the newly formed Conservation, Infrastructure and Efficiency Fund, which will be managed by a specially formed committee. They have agreed to also pay $3.60 per acre-foot of groundwater diversions to cloud-seeding projects that directly benefit…
