Heartrock Ranch, Idaho, 2011

An ecological restoration compatible with livestock operations that increased wild trout and wildlife populations by eliminating flood irrigation by raising the water table in addition to constructing 13 miles of stream channels and 44 oxbow ponds and wetland/waterfowl areas. Ten years of monitoring was conducted, including groundwater, surface water, fish abundance, redd counts, and benthic surveys, to determine the project was effective at meeting project goals, including delivering more return flows to the downstream reaches.
