The remaining gate is used to release water into the Welch Lateral Ditch. This is the lowest of the outlet works with the downstream invert corresponding to 0 gage height, On June 25, 1990, this outlet developed a sink hole above the outlet pipe where the outlet pipe is crossed by an irrigation lateral which runs along the downstream toe of the dam. Video inspection of the outlet pipe revealed water leaking through several joints and a longitudinal crack along the top of the pipe approximately 50 feet in length. The camera was unable to travel further than 100 feet into the outlet pipe from the south end as the pipe appears to decrease in diameter from IS-inch 1.0. to about 15 inch I,D, at this location. The location of the decrease in pipe diameter corresponds with the sink hole location, A temporary repair and monitoring program was designed by Rocky Mountain Consultants, Inc., approved by the State Engineer's Office, and constructed. The State Engineer's Office has mandated continuous monitoring of the temporary construction and storage restrictions until permanent repairs or modifications are made. The storage restrictions call for the high water surface to be limited to elevation 20. As noted above, at elevation 24 the embankment between Lake No. 1 and Lake No.2 is visible and separates the two lakes allowing releases from the remaining portions of Welch Reservoir (Lakes 2, 3, and 4) to be made from Outlets 2 and 3 into the Handy Ditch. Outlet No. 2 is located near the eastern end of the embankment. It consists of a gate screw, 36-inch diameter metal gate, and a 34-inch 0,0, corrugated metal conduit embedded in concrete.
