<br />II.A.2. Implement levee removal strategy at high-priority sites <br />II.A.2. b. Construction (levee breaching). <br /> <br />VI. Accomplishment of FY 2002 Tasks and Deliverables: <br /> <br />Capital funding had been earmarked to restorelenhance habitat at the following three sites <br />in 2002. Construction had originally been scheduled to begin in late summer or early fall of <br />2002. <br /> <br />Colorado River <br /> <br />GJ Pipe. This gravel pit was acquired in fee from Grand Junction Pipe and Supply in FY <br />2000. Located at Colorado River RM 165.5, it is approximately 5 miles downstream <br />from the confluence with the Gunnison River. The plan for this site was to lower <br />portions of the levees to allow entrainment of drifting razorback sucker larvae during <br />spring runoff. The construction costs had been estimated at $99,800 plus $77,000 in rip- <br />rap. <br /> <br />The levee on the downstream end of the site has been eroding away over the years, and <br />the river is expected to eventually breach the levee, possibly within the next few years. <br />Because FWS-Refuges expressed concern about potential liability if adjacent landowners <br />perceived that they had been affected by Recovery Program construction activities <br />(August 8; 2002 pre-construction meeting), a decision was made to postpone <br />construction. The levee erosion rate will be monitored to predict when the levee may <br />breach naturally, and decisions regarding habitat enhancement options will be made at <br />some future date. <br /> <br />'Valter Walker SW A. More adult Colorado pikeminnow and razorback sucker have <br />been found using CDOW's Walter Walker State Wildlife Area than have been captured <br />throughout the entire remainder of the Colorado River. It is believed that these fish have <br />been attracted to the habitat complexity and diversity of the area. The plan for this site <br />was to lower the upstream levee in three locations to help maintain the diversity and <br />complexity of the area. The construction cost had been estimated at $38,200 plus <br />$22,000 in rip-rap. Recently, a gravel mining company located adjacent to the site has <br />agreed to remove the levee at no cost, and removal is scheduled to begin in March 2003. <br /> <br />C-6 construction page 2 <br />
