Spring runoff hasn't really taken off yet. Rivers are starting to rise, but other than some off-colored water at times most remain very fishable at this time. However, things can quickly change so expect to adjust if you head out.
The Blue River below Dillon remains a great place to fish with plenty of active fish. While the action has slowed a bit, part of the issue is the fish have spread out from the earlier stocking and fishing pressure has increased, enough that company is a given. Midges and blue wing olive patterns are the favored patterns, both nymphs and dries.
The Eagle River around the confluence with Gore Creek is flowing higher, but is generally fishable. Pheasant tails, prince nymphs and caddis nymphs are a good bet. Further downstream the waters get murkier, and that goes for the Colorado and Roaring Fork rivers also. If you try them, larger patterns, such as stones and streamers in browns or blacks, will work.
Reservoirs will increasingly be the better areas to fish. While Dillon is close, the action has been slow. It might be better to travel a little. One option is Turquoise Lake. The water levels are down, but most anglers are managing a few rainbows on typical baits. Spinners, spoons and jigs are producing an occasional lake trout.
South Park waters have been generally slow, with Tarryall and Antero reservoirs reporting the best action. Of the two, Tarryall has been best, but the fish are on the smaller side.
Another option would be to run over to Granby Reservoir, where the lake-trout action is starting to pick up with a few large fish being caught shallow by both trolling spoons and minnow-style lures. Browns are also fairly active near shore.
