Page 2 February 10, 1986 Terrance L. O'Cpnner RECLAMATION ACTIVITIES Topsoil continued to be stripped and stockpiled according to the Reclamation Plan. Approximately 35, 000 yards were stripped from the McNulty dump area and added to the surrounding stockpiles. A 5. 5 acre slough area at the base of Robinson Dam No. 1 was filled, repaired, and brought into configuration commensurate with the remainder of the dam as a precursor to reclamation activities scheduled for the latter part of Phase III of the Reclamation Plan. At this time, the toe drain and access drainage systems were modified and improved to ensure long-term stability of the dam. Additionally, the drainage system at the toe of Dam No. 4 was upgraded and modified extensively to ensure stability. The area around the dam and pump station was graded and seeded with the established, high-altitude "Climax" seed mix. Other reclamation related activities included preliminary engineering studies relative to haul roads, the Colorado 91 highway crossing, and dewatering of the Robinson tailing pond. This information was developed in preparation for the start of reclamation activities on Robinson Dam No. 1 and the Robinson pond in the mid-1990 's. MISCELLANEOUS INFORMATION Previously revegetated areas continued to be monitored during 1985. These areas continue to show good results. Dr. William Berg of the Southern Plains Range and Research Station conducted an evaluation and assessment of various Climax test plots during the year. Results of these evaluations will be presented in formal papers at the 1986 High Altitude Revegetation Workshop at Colorado State University. Much of Dr. Berg ' s data has been submitted to the Mined Land Reclamation Division, and copies of the final papers will be submitted when they become available. The Arkansas River In-Stream Habitat Improvement Project, a permit stipulation of the CWA §404 permit granted Climax for its 900 Level Development Project, was completed in 1984 and approved by the Colorado Division of Wildlife in January 1985. The U.S. Army Corps of Engineers inspected the diversion and containment site in June 1985 and closed the file on this 404 permit.
