<br />~ <br /> <br />. <br /> <br />. <br /> <br />co <br />~ development in the Head Lake-San Luis Lake area, water deliveries to Alamosa <br />~ <br />~ National Wildlife Refuge, a request by Bureau of Land Management (BLM) for deli- <br />e <br /> <br />very of project water to the Blanca Wildlife Habitat Area, and fishery enhan- <br /> <br />cement considerations for the proposed conveyance channel. Resolution of a <br /> <br />revised mitigation and enhancement plan is expected this spring. <br /> <br />Advanced planning studies have also progressed on the proposed eonveyance chan- <br /> <br />nel and Stage 1-2 laterals. Analysis eompleted last spring of hydraulic conduc- <br /> <br />tivity data collected earlier indicated that only minor leakage would occur from <br /> <br />an unlined channel, thus it is not planned to line the conveyance channel. In <br /> <br />August a soils-sampling contract was completed along the southern portion of the <br /> <br />conveyance channel alinement, and last winter some possible construction alter- <br /> <br />natives for a channel crossing of the Blanca Wildlife Habitat Area were sent to <br /> <br />BLM and FWS for comment. Lateral designs for a portion of the Stage 1-2 well <br /> <br />field laterals were completed last summer for technical review by our Denver <br /> <br />staff. Award of contracts for the Stage 1-2 channels and laterals are scheduled <br /> <br />for the first quarter of fiscal year 1983. <br /> <br />Long-term test pumping has continued in the Stage 3 area and, under our eoopera- <br /> <br />tive program with the U.S. Geological Survey, colleetion and analyses of hydro- <br /> <br />logic data are continuing. These analyses include computer modeling of aquifer <br /> <br />characteristics and water-table drawdowns to develop preliminary well-field <br /> <br />designs for Stage 3. Installation of additional test wells in Stage 3 area is <br /> <br />scheduled for this summer. Work has also begun on preparation of a supplement <br /> <br />to the Final Environmental Statement which was filed in August 1979. Filing of <br /> <br />a Draft Supplement to the Environmental Impact Statement, scheduled for the last <br /> <br />quarter of fiscal year 1982, is required to permit anticipated start of <br /> <br />eonstruction of Stage 3 well-field facilities that same quarter. <br />
