A study of the effects that continuous pumping and lining of laterals, <br />to reduce seepage losses, may have on the water table will be made. <br />This will require assisting the U.S.G.S. in adapting surface water <br />system into the San Luis Valley Analog Model to determine impact of <br />proposed canal lining and pumping on the water supply. <br />Water demand - will assist planning engineer in developing crop demand <br />for irrigation water. <br />Climate - Weather Bureau records will be used to obtain average temperature, <br />precipitation, frost -free growing season and evaporation. <br />Sedimentati and Geological <br />No specific geologic or sedimentation investigations are planned for <br />this watershed. Geologic assistance will be provided in the engineering <br />and hydrologic investigations as needed. <br />Biolo <br />A biologic- recreational reconnaissance survey will be made with the <br />Colorado State Division of Game, Fish, and Parks, and the Bureau of <br />Sport Fishery and Wildlife. <br />Environmental Evaluation <br />Alternatives will be studied giving consideration to preservation and <br />enhancement of the environment. A preliminary field review has been <br />made and no major adverse impacts were identified. <br />Archeological, Historic, and Scientific <br />All reasonable actions will be taken to learn the existence of Archeological, <br />Historic, and Scientific sites, and if found, to notify those in a position <br />to provide necessary protection or salvage. The National Park Service, <br />Midwest Regional Office, Omaha, Nebraska, will be kept informed. The <br />National Register of Historic Places will be searched for possible entries <br />in the watershed. <br />Planning Engineering <br />Preliminary onsite investigation and canal and structure dimensioning <br />was considered during preparation of the Watershed Investigation Report. <br />Structural design for new drop, check, syphon, turnout, measuring <br />structures, and canal lining will be according to standard designs. <br />Special Soil Conservation Service approved designs will be used where <br />standard designs are not adequate. Contract cost will be <br />determined using most recent PL -566 contract costs. <br />-2- <br />
