THE LOWDOWN: The warning we presented in our Fork report is perhaps even more applicable to the Colorado, so it bears repeating: 

Keep an eye out for rapidly-rising water temps. While the rain is likely to help a bit, the gauges have been breaking 70 degrees mid-day thanks to this long and brutal stretch of hot, dry weather. There are no mandated closures at this point, but don't be surprised if you start seeing notices in the coming weeks. Protecting the health of our resource is paramount this time of year; think short fights, quick releases, and minimal handling. 

The "Collie" has been pretty consistent in regards to flows and hatches so far this summer. Monsoonal trends can add some color but so far, so good. By all accounts the hopper bite is still hot, but the fishing is only going to get tougher now that flows are low and steady.

Most of you know that cloudy days are best, especially for a slow-release hatch. The Colorado is a big, brawling river- ideal for a drift boat but it can be accessed on foot. This river is a bit more of a quality than a quantity fishery, so be prepared to hook onto some pissed-off fish that will dump your reel in a few seconds.

Wade-fishers should exercise caution in the biggest river of the valley, but popular wading spots include the confluence with the Roaring Fork, Dino Boat ramp (both above and below the ramp) and upstream of South Canyon rapid.
