Upgraded two spring heads, a conveyance channel, and a 0.75-acre man-made pond serving as surge storage capacity. The site has been inhabited by tribal heritages, ranchers, and missionaries and used as a sacred area for ceremonies for hundreds of years and is the habitat/water source for numerous desert creatures. Project highlights: construction of refugias for holding/protecting wildlife during construction; installation of pipe to provide a bypass for the spring; dewatering; compaction of berm and pond excavation and reconstruction; liner installation and placement of 1,200 cu. yds. of cover; placement of rock/stone to provide habitat for the endangered species and limit plant growth; construction of concrete channel from the spring to the new rock channel to allow for upstream migration; construction of an inlet rock chute from the new concrete channel to the pond; and site restoration including reintroducing the displaced wildlife.
