Rivers continue to run unseasonably low and very fishable, which is most unusual this time of year. Look for the best fishing to be in the morning when runoff is at its lowest. The Colorado River remains one of the better ones with the Salmonfly hatch tapering off. While off-colored large nymphs continue to work. On the lower sections, below Dotsero, anglers are doing well with silver slab spoons and inline spinners.
South Park waters have been fishing well, especially Antero Reservoir. Trolling is producing a lot of fish, although very few fish over 20 inches are being caught. Just be prepared for company, as boat traffic has been heavy. Spinney Reservoir is popular with fly fishers, but several are doing well jigging small tube jigs. Surprisingly very few pike are showing up.
With all the anticipation of the road to Jefferson Lake opening, unfortunately the fish missed the memo. While a few rainbows have come to the net using spinners and flies, the action has been disappointing.
Granby is worth the drive right now for good action, primarily for smaller rainbows. Those jigging tubes off the dike areas are doing well for small lake trout. Tipping them with sucker strips often helps with the action.
Dillon Reservoir should not be ignored, as it has been stocked this spring. While the reports don't indicate fast catching, working typical baits around the inlets during the day will often produce a few fish. Watch for surface action, and be ready to switch over to a fly and bubble rig. Small and black, such as an ant pattern, would be a good place to start.
