Spring run-off continues to abate with each passing week making for much improved river fishing. Just be aware that as we move into summer that afternoon thunderstorms can quickly change a river from fishable to a mud flow in minutes.
The Eagle River is fishing well, and wading anglers are finding it’s increasingly easier to get around. Nymphing with stoneflies and stripping streamers has been the most productive method, but look for the caddis hatched to pick up shortly, providing some great evening dry fly action.
The upper sections of the Colorado River are clearing. Water flows are still high, so floating is a great option. For dry fly action give salmon fly patterns a try. Although, large attractors and hoppers are fair choices as the fish are looking for large targets. If surface action is slow, stonefly nymphs in faster runs are an excellent choice.
The Roaring Fork River is improving daily. As with most of the rivers, nymphs, especially attractor patterns, are effective at this time. Look for the Drake hatches to start showing up soon.
The Blue River below Dillon has dropped below the 1,000 cfs mark. While high, it is fishing well with Mysis shrimp, midges, small mayfly and small attractor patterns. Work the shorelines as the fish tend to hold tight to the banks during periods of higher flows.
Jefferson Lake is producing a few lake trout. Working jigs tipped with sucker meat from a boat or canoe is an excellent tactic.
The lake has been seeing a lot of anglers as of late, most fishing for rainbows. So if you go, expect company.
Spinney Mountain Reservoir is still fishing well for the fly fishers. There have been lots of boats and float tubes on the water. Working midges below a float is a favored and productive tactic. Don’t be afraid to work woolly buggers tight to the shoreline, especially early and late in the day.
While not the hottest action, shallow fish are feeding fish, and more aggressive than fish in deeper water.
Eleven Mile Reservoir is full. Fishing has been mixed, depending on tactics. Those using bait are finding the action to be slow. Good hatches are being reported in the evenings, so a fly and bubble rig is an excellent choice at those times.
