Drop in groundwaler may reduce wetland and planls, fish, and/or wildlife from decreased riparian habitat along the Colorado River, which waler levels (and associated drop in may impact sensitive species, such as razorback groundwater level) of the Colorado River suckers, bony tail chub, Yuma clapper rail, California between Parker Dam and Imperial Dam. black rail, ~outhwestern wiUow flycatcher, and yellow-billed cuckoo. Impacts and mitigations were addressed in the 2001 FWS Biological Opinion.

The Her will address both plant conservation measures. result in impacts comparable to the proposed lA. and fish and wildlife species within the no service area and the Salton Sea. Construction of conservation projects, potential reduced flow and changed water quality in the drains, possible impacts on Salton Sea, and the potential for fallowing as a conservation method are all addressed in the Hep. \::' ~ " " ~ ;;.
