The rivers are in prime condition, low and clear. Cooler weather has dropped the water temperatures enough that even afternoon fishing is once again on the menu. On those warm (almost hot) afternoons, taking a temperature reading is a good idea.
The aspen and cottonwoods aren't the only source of fall color, as the browns are getting ready for spawn and are more aggressive than normal. Streamers through gravelly areas and pools above and below them are a great choice. Nymphing anglers should consider attractors such as glo-bugs and San Juan worms. However, if it is obvious the fish are on redds (hollows in sand or gravel, scooped out as a nest-like place to spawn), please don't fish them or wade those areas.
The Blue, Colorado, Eagle and Roaring Fork rivers are all fishing well.
Green Mountain Reservoir remains low, but that hasn't kept folks away. Right now, it's attracting anglers hoping for the kokanee to be running. While a few are being snagged, the action is far from hot. Better to concentrate on the river or main lake where rainbows have been fairly cooperative on most standard baits.
Another choice is Granby Reservoir, which is slated to see the water levels continue to drop through the fall. Lake trout action is starting to pick up, with the more successful anglers jigging anywhere from 60-120 feet down off main reservoir points and underwater ridges. Jigging spoons are a
good option, as is a good topographic map
or depth finder.
South Park waters continue to be popular, but the best reports are coming from Eleven Mile Reservoir. Sporting good water levels, the water is fairly clear with visibility to 4 feet or better. Most of the algae bloom appears to have passed, and successful anglers are concentrating on depths from 5-25 feet. Minnow-styled lures have been productive, but small tube jigs worked near or off the bottom are effective as the fish have been feeding heavily on crayfish.
