<br />. <br /> <br />. <br /> <br />~ Bureau of Land Management <br /> <br />CJ1 <br />00 During this reporting period, the BLM's salinity control <br />~ activities involved implementation of erosion control <br />practices in Colorado, Utah, and Wyoming. BLM estimates <br />these activities plus previous years activities have reduced <br />the salt contribution to the River by over 400 tons/year. As <br />stated in its July 1, 1987 report to Congress, the BLM goal <br />is to identify and evaluate salinity control issues through <br />the Resources Management Planning Process. <br /> <br />Geological Survey <br /> <br />The Geological Survey's Water Resources Division <br />provides and analyzes hydrologic information to assess the <br />Nation's water resources. <br /> <br />To provide information required by the federal, state, <br />and local agencies to address Colorado River water quantity <br />and quality problems, the Water Resources Division in <br />cooperation with state and other federal agencies operates <br />and maintains a network of about 511 stream gaging stations <br />and 141 water quality stations in the Colorado River drainage <br />basin. The USGS provides data from its National Stream <br />Quality Accounting Network (NASQAN) at 11 of 20 stations <br />which Reclamation uses for evaluating salinity control in the <br />Basin. Additionally, the Geological Survey is conducting 11 <br />water quality investigations in the Colorado River basin. <br />Although the major objectives of these studies are not <br />directed at salinity, information developed can be used to <br />evaluate the extent of salinity as a problem in the area <br />under investigation. <br /> <br />Department of Agriculture <br /> <br />In F.Y. 1989 Congress appropriated $5.452 million for <br />CRSC. The following describes the major salinity control <br />activities carried out by the USDA. <br /> <br />Bir Sandy River Unit - To date, 7 contracts have been <br />signed or onfarm improvements, mainly sprinkler systems. A <br />total of $427,000 has been obligated in these contracts. <br />During the first signup period in 1988, 31 requests to <br />participate were received. Approximately $1.4 million in <br />cost share funds are needed for salinity control contracts <br />associated with the applications on file. Estimated annual <br />seepage reduction resulting from the installed practices is <br />1,035 acre-feet with a salt load reduction of 2700 tons per <br />year. <br /> <br />-11- <br />
