Regional Water Sustainability Project receives additional $1.2 million

An additional $1.2 million was approved for a 30% design plan for the Lower Clearwater Exchange Project. The sustainability project is in cooperation with the Lewiston Orchards Irrigation District, the Nez Perce Tribe, and the Bureau of Reclamation.

Per the IDWR:

The project is intended to fully enact a water exchange between Lewiston Orchards Irrigation District (LOID) and Nez Perce Tribe by allowing LOID to divert irrigation water from the Clearwater River to replace pumping from a declining aquifer and surface water streams that support imperiled steelhead and salmon stocks. LOID and the Nez Perce Tribe paid for the initial design work and are pursuing additional cost-share funding from the Bureau of Reclamation.

Board also funds two Eastern Snake Plain Aquifer projects

The Idaho Water Resource Board also approved two smaller amounts of funding related to the Eastern Snake Plain Aquifer projects. $571,000 in ARPA funding was granted to construct the Poitevin Injection Well Site Expansion, which will cover the cost of developing two recharge wells. An additional $94,000 was granted to conduct a System Capacity Improvement Study with the Butte Market Lake Canal Company, in order to explore options for improving delivery capacity related to aquifer recharge.
