New committee takes on Eastern Snake Plain Aquifer

Idaho News
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.

Water use soaring

Idaho News
By Bill Buley; Coeur d'Alene-Post Falls Press A sprinkler sprays water on a Coeur d'Alene lawn on Monday. Bill Buley COEUR d'ALENE — In June, the city of Coeur d'Alene pumped 780.8 million gallons of water.  If that sounds like a lot, it is.  That was 350 million gallons more than the same month last year when the city pumped 430.8 million gallons. Terry Pickel, Coeur d'Alene water department director, attributes the soaring water use to hot and dry conditions and residents' efforts to keep lawns green by running sprinklers. July is shaping up much the same.  "I would certainly expect to see a significant July increase as temps are soaring," he wrote in an email to The Press on Monday.

Summer heat can cause dangerous conditions in Idaho’s rivers and lakes

Idaho News, Research
By Drew Pendleton; Dept. of Health and Welfare As temperatures increase, so does the likelihood of a cyanobacterial harmful algal bloom (cyanoHAB). CyanoHABs are caused by cyanobacteria, and the toxins they produce are harmful to humans, pets, livestock, and wildlife. CyanoHABs can change and increase rapidly if conditions are right. They favor warm water, sunlight, and specific nutrients in the water. These blooms can last throughout the summer into fall. The Idaho Department of Environmental Quality (DEQ) samples and analyzes Idaho water bodies for cyanoHABs. The test results are provided to the Idaho Department of Health and Welfare (DHW) and local public health districts, and they decide if a health advisory should be issued. For information on advisories, visit the DHW’s Idaho Recreational Water Advisories map for more information. The…
