the study. WWE suggests a project site visit and a meeting with a member of the LPWCD and CWCB staff during the time WWE is formulating alternatives. WWE anticipates the entire study can be completed within one year after notice to proceed. If LPWCD or CWCB desires a different completion schedule, WWE is willing to make all possible efforts to accommodate CWCB needs. In any event, WWE will notify CWCB of progress and available information. II. PROPOSED LONG HOLLOW DAM Introduction The proposed Long Hollow dam and reservoir will be located in the NE1/4 SW1/4 Section 32, T32N, R12N of the New Mexico Principal Meridian. The dam will be located approximately 0.5 mile above the confluence of Long Hollow with the La Plata River at the confluence with Government Creek. The current owner of the site is Mr. Robert Taylor. Mr. Taylor has expressed interest in making the site available for a dam and reservoir. A reconnaissance-level, area-capacity study for the dam and reservoir was conducted by Harris Water Engineering. This study indicated a dam at the site with a crest elevation of 6,276 feet(streambed elevation is 6,200 feet)would have a storage capacity of approximately 1,550 acre-feet. A dam with a crest elevation of 6,314 feet could hold approximately 5,432 acre-feet of water in storage. The Harris report also indicated a 76- foot-high dam would require a total earthwork volume of about 288,000 cubic yards. This dam would have a 3:1 upstream slope, a 2.5:1 downstream slope, and a 25-foot crest width. The entire base of the dam would be stripped to a 2-foot depth and a 50-foot wide and 40-foot deep key trench would be included along the centerline of the embankment. No site-specific information is currently available on the geology or the geotechnical engineering properties of subsurface materials at the dam and reservoir site, and little site-specific information is available relative to topography, wetlands,hydrology, cultural resources and threatened/endangered species in the dam and reservoir area. Study Objective The objective and scope of the study are based on: • the Colorado Water Conservation Board(CWCB) guidelines for a feasibility- level planning study, • a site visit on May 30, 2001, in the presence of Mr. Robert Taylor whose family has owned the property in Long Hollow for many decades, • a preliminary review of readily available geology publications for the dam and reservoir area and two U.S. Bureau of Reclamation(USBR) dam site investigations within ten miles of the site, and • WWE's experience on similar projects and knowledge of the La Plata River basin. 10
