South Platte: Deckers
Weekly Overview from FlyCastUSA.com:
April 6, 2020
Last week, Deckers experienced the biggest decrease in flow that it’s seen all year, dropping from 210 cfs to 120 cfs. Since then, flows have risen back to the 150 cfs range. The drastic change in flow temporarily altered trout behavior and feeding. With several days of steady and healthy flows, trout have settled back into their spring lies. Prior to 11 am, focusing on the deep and slow water continues to produce the best results. Fish these sections with a heavy double midge or baetis/midge nymph rig. As the day progresses, trout have become more active and willing to move for a well present fly. Our go-to rigs during the afternoon have been a Mercury Pheasant Tail followed by a Chocolate Foam Wing Emerger or a JuJu Baetis followed by an olive RS2. Electric Caddis, Guides Choice Hares Ears, egg patterns and Darth Baetis are great alternative lead patterns. We’ve found trout feeding in faster water, so don’t ignore the shallow riffles, head of runs and transition areas. Be on the lookout for midge and BWO hatch activity after 11 am. BWOs were a big hit last weekend!
