With the delightful fall weather we've been experiencing most days, the rivers remain some of the best fishing options. Two of the top choices are the Eagle and Colorado rivers. As the waters cool, the browns are becoming increasingly aggressive, thus gaudy streamers and attractor patterns will be a great choice. However, it's wise to avoid wading or fishing redds.
Streamers are a good choice, but anglers should also be on the lookout for occasional hatches of blue-winged olives, midges and caddis. During the hatch, anglers can experience great dry-fly action. The rest of the time, nymphing will be your best bet. With the low, clear waters, use unweighted, or lightly weight, patterns on a 5X or 6X tippet.
Another good river to fish right now is the Dream Stream (the South Platte in South Park). Both kokanee and brown trout from Eleven Mile Reservoir have been showing up in reasonable numbers. Streamers and bright flies such as San Juan worms have been the choice of many anglers. Don't overlook standard fare, as going against the crowd is often a good tactic. The downside to this wonder river is the crowds. Expect lots of company if you go.
Many reservoirs are also fishing well right now, but two that are attracting lots of attention are Granby and Eleven Mile. Eleven Mile is producing a few northern pike and good numbers of healthy, 16- to 20-inch trout, mostly rainbows. Trolling remains the top-producing tactic. Spoons are good choice, especially worked near shore in waters under 30 feet deep.
Granby is a different story, with lake trout being the main attraction. Look for the fish to be gathering off submerged shoals 10-60 feet down. Vertical jigging with spoons and tube jigs continues to be a great tactic. Look for similar conditions on Green Mountain and Williams Fork reservoirs and you should also do well with lake trout.
