CC187G . . San Luis Lake Elevation of San Luis Lake - 7516.0 feet (4,459 acre feet) (801 acres) Total Dissolved Solids (TDS) - 1,144 mg/I Note: Looking at the TDS for San Luis Lake for the past three years The TDS in 2000 was holding around 600 then in April of 2001 began to climb and reached 800 in about July of 2001. In April/May 2002 you see the jump to 1000 with a TDS of 1144 as of October 9th, 2002. Other Operational Items On July 1, CH01 and CHO 2 were opened to deliver approximately 5 cfs each t,o the Alamosa Wildlife Refuge, On July 3, in an effort to provide more than 1 cfs to the Rio Grande a special meeting was held and the outcome was to reduce the delivery to the Refuge from 10 cfs to 5 cfs and immediately deliver the water to the river and to reduce the inflow to San Luis Lake from approximately 10 cfs to 5 cfs, Agro annual report 2001 - An average of 1,264 acres within the project boundary are showing a significant decrease in vegetation from the Pre-project baseline. This amount is less than 2000 and 1998, and is similar t01999. According to Agro's report much of this decrease is attributed to factors other than project pumping. This decrease is far less than the 8,460 acres that were predicted in the FEIS and for which mitigation water is being provided. An average of 857 acres within the project boundary show a significant increase in vegetation from the Pre-project baseline. This amount is similar to the past three years. Areas within the project boundary that show an increase in vegetation include lands that are receiving mitigation water. USGS annual review 2001 - USGS completed the 2001 Quality Control/Quality Assurance Review of the Closed Basin Elevation Wells (EW) for the period of January 1- December 31,2001, USGS commented that the Bureau is doing an excellent job in collecting the data, in the correction of the data, and computation methodology. Comparisons were made between the USBR transmitted mean daily water levels, USGS computed mean daily water levels, USBR computed mean daily water levels, USGS field measured water levels, and the USBR field measured water levels. Twelve wells were randomly selected by the USGS for the comparison and annual analysis, The program for the next year will continue with the focus on more physical measurements, looking at areas of concern, and establishing a review process rather than a duplication of effort.
