Downstream <br />riparian resources could be negatively impacted due to lowered water <br />avail abil ity. <br /> <br />o Holding Reservoirs--Would inundate large areas or riparian and stream <br />habitats, eliminating their value to important fish and wildlife <br />species. <br /> <br />o Conveyance Facilities--Coul<l block migration and movement patterns. <br />Indi vidual animal s could be trapped in open canal s. Use of some <br />streams to convey water in Nebraska and Colorado could provide <br />localized benefits. <br /> <br />o Terminal Reservoirs--Inundation of large acreages of stream and <br />riparian habitats would negatively impact valuable resources. With- <br />out adequate releases, downstream aquatic and riparian resources <br />would be negatively affected as well. Terminal reservoirs could <br />create aquatic habitats within semi -arid area, but fl uctuating water <br />levels would render management largely ineffective. <br /> <br />STRATEGY FIVE (MS-5A and 5B) <br /> <br />Pursuant to the legislation authorizing the High Plains-Ogallala Aquifer <br />Regional Resources Study, the U. S. Army Corps of Engi neers conducted the <br />study of potent i al interstate, i nterbasi n transfers of water to termi nal <br />reservoi rs in the Hi gh Pl a i ns Regi on for i rri gat i on. The Corps was assi sted <br />by the U.S. Fish and Wildlife Service which assessed the impacts on fish and <br />wi 1 dl i fe resources at the poi nts of di versi on, the conservat i on storage <br />reservoi rs, along the conveyance' rout i ngs (canal s, si phons, pi pel i nes, <br />pumpi ng pl ants, ri ver crossi ngs), and at the termi nal reservoi rs. The <br />environmental assessment did not extend downstream of the points of diversion <br />along the source streams. Responsibility for overall direction and prepara- <br />tion of the final report on the Corps' study was assigned by the Chief of <br />Engineers to the Southwestern Division.
