Fished the South Platte at Chatfield today hoping the run was on and it is starting but not alot of fish spotted. Ended up catching 4, hooking five in 2 hours on a size 20 red midge. Nothing took the gray RS2. The water is high and no luck at the concrete structure below the bridge. Caught them all at the last deep hole above the bridge, where the tree was cut down. All males 14 to 16 inches. A guy I met said a 20 incher was caught this weekend on crawlers (and kept). I would wait another week. Quincy tomorrow!
