, project is in operation and to continue for at least 2 years. The monitoring will determine the relative abundance of the species and the lengths of the fish sampled. In addition, water samples and flow measurements will be made during the monitoring process. The WPRS will fund the incremental difference between the present and the monthly monitoring, furnish water sampling materials, and provide for the water quality analysis. Monitoring will be conducted at stations mutually agreeable to both the F&WS and the WPRS. 2. In-Stream Flows. The most direct adverse impact of the project will be some river depletion below the La Verkin Springs. Although the water is presently highly saline and uninhabitable by fish during low flows, the woundfin has been found above the C P National Corporation Powerplant No.4 when there is sufficient flow to dilute the springs' water. After consulting with the F&WS, the WPRS has decided that if desalting proves to be the most feasible plan, product water from the plant (about 8.7 ft3/s) would be returned to the river at a point about 1,500 feet downstream from the Highway 9 bridge. This point is well upstream of the C P National Corporation Powerplant No.4 outlet and marks the upper range of the woundfin. The exact location of the product water outflow will be determined when the final design plan is completed, however, the product water will be returned as far upstream as gravity flow will permit. This enhancement measure will allow the woundfin to inhabit this section of the river for longer periods during the year. While 8.7 ft3 / s are not sufficient to sustain a large population of woundfin, it could provide a minimal habitat for small numbers of fish and the flow throughout the year will enable woundfin to reoccupy dry river reaches faster when riverflows are sufficient to support large numbers of fish. In addition, the WPRS has obtained an agreement from water users to purchase water rights for the project in the event a desalt- ing plant is built. The agreement calls for three canal companies to divide the water replacement requirement. Thus, if 3.2 ft3/s are needed, these water replacement requirements would be distributed 14 ,..........3 I. ~)
