<br />fj. <br />L:; <br /> <br />Exhibit A <br />Grant for Proposed Feasibility Study of Long HoIlow Reservoir and Red Mesa Reservoir Enlargement <br /> <br />. <br /> <br />. <br /> <br />p <br />1': <br /> <br />The work required to accomplish the outlined data collection and alternatives analysis <br />cannot be absolutely defined in advance and the final costs may differ somewhat from <br />those estimated. However, the maximum estimated fee would not be exceeded without <br />prior written approval. <br /> <br />Schedule <br /> <br />IT <br /> <br />IT: <br />tf <br />~. <br /> <br />WWE proposes to initiate the investigation promptly after being given notice to proceed. <br />WWE will report to the La Plata Water Conservancy District (LPWCD) frequently and <br />keep the CWCB staff informed of preliminary information as it becomes available during <br />the study. WWE suggests a project site visit and a meeting with a member ofthe <br />LPWCD and CWCB staff during the time WWE is formulating alternatives. <br /> <br />WWE anticipates the entire study can be completed within one year after notice to <br />proceed. IfLPWCD or CWCB desires a different completion schedule, WWE is willing <br />to make all possible efforts to accommodate CWCB needs. In any event, WWE will <br />notify CWCB of progress and available information. <br /> <br />II. PROPOSED LONG HOLLOW DAM <br /> <br />r.:-.-. <br />j..:: <br />i. <br /> <br />i." <br />~, <br /> <br />r: <br />, ,~ <br />,.. <br />c: <br /> <br />Introduction <br /> <br />The proposed Long Hollow dam and reservoir will be located in the NEIl. SWII. Section <br />32, T32N, R12N of the New Mexico Principal Meridian. The dam will be located <br />approximately 0.5 mile above the confluence of Long Hollow with the La Plata River at <br />the confluence with Government Creek. The current owner of the site is Mr. Robert <br />Taylor. Mr. Taylor has expressed interest in making the site available for a dam and <br />reservoir. <br /> <br />L <br />r <br />b <br />~ <br /> <br />A reconnaissance-level, area-capacity study for the dam and reservoir was conducted by <br />Harris Water Engineering. This study indicated a dam at the site with a crest elevation of <br />6,276 feet (streambed elevation is 6,200 feet) would have a storage capacity of <br />approximately 1,550 acre-feet. A dam with a crest elevation of 6,314 feet could hold <br />approximately 5,432 acre-feet of water in storage. The Harris report also indicated a 76- <br />foot-high dam would require a total earthwork volume of about 288,000 cubic yards. <br />This dam would_have a 3:1 upstream slope, a 2.5:1 downstream slope, and a 25-foot crest <br />width. The entire base of the dam would be stripped to a 2-foot depth and a 50-foot wide <br />and 40-foot deep key trench would be included along the centerline of the embankment. <br /> <br />No site-specific information is currently available on the geology or the geotechnical <br />engineering properties of subsurface materials at the dam and reservoir site, and little <br />site-specific information is available relative to topography, wetlands, hydrology, cultural <br />resources and threatened/endangered species in the dam and reservoir area. <br /> <br />I: <br />li <br />C <br />L. <br /> <br />r:; <br />u <br />n <br />lJ <br /> <br />Study Objective <br /> <br />The objective and scope ofthe study are based on: <br /> <br />· the Colorado Water Conservation Board (CWCB) guidelines for a feasibility- <br />level planning study, <br /> <br />r,.':' <br />
