With the warm weather, look for most rivers to be high and roiling, except for the highest streams and tail waters. With mildly off-colored waters considering large dark nymphs, such as stonefly. Streamers are also a solid choice. Tailwater fisheries are heavy with midges making them an excellent choice year around.
Right now the best option is to hit the recently opened reservoirs. Word is Granby is now ice free, and the sunset boat ramp is open. This is a great time to work shallow waters with large streamers, or lures, for the lake trout, while they’re shallow. There’s about a 2-4 week window.
South park reservoirs are doing well. Spinney Mountain remains low and limited to hand launch water craft. Shore anglers can do well with a couple tactics. Streamers are a go-to for many. The trick is to slow down and use an erratic cadence. Too many work their flies too shallow and fast. The other tactic is simply a midge pattern suspended below a strike indicator. A leader should be enough to keep the fly just off the bottom. Retrieve should be non-existent.
Pike anglers are picking up a few fish at both Eleven Mile and Tarryall as the fish move shallow. While large, bright lures are the norm, consider downsizing and going with darker colors. This is often effective with heavily pressured fish.
Green Mountain Reservoir continues to lose its remaining ice. Fishing has been solid close to shore. Fish are often within a rod length or two away. While a variety of baits will work, fan casting spoon or spinners are just as effective.
