Trouts Frisco Forecast | August 2023 Edition

Zeke Hersh / Aug 18, 2023

Welcome to the Trouts Monthly Frisco/Mountain Forecast!

The summer sure has flown by this year. It’s really hard to believe fall is just around the corner. While I will miss the summer temperatures, hatches, and all that this short window of time offers us here in Colorado, fall is also a very special time here in our state.

We will start to see some cooling temperatures as we move toward the end of August and into early September. With these cooling temperatures, there can be a resurgence of fish and bug activity. Along with this, the number of anglers starts to diminish and all of these make for some great reasons to get on the water in the weeks to come.

Here are some sections I will be looking to fish in the weeks to come.


The Colorado River from Glenwood Springs to Rifle:

With some cooler temperatures starting to enter Colorado in the weeks to come, I will start to think about venturing downriver to the Glenwood Springs area. This section can fish extremely well in the fall and early winter. This will extend my dry dropper and float fishing for at least a month compared to sections upriver.

The Colorado River from Kremmling to Dotsero:

Although I am thinking about fishing some of the lower sections as we enter fall, this section has a couple of months left of excellent fishing. The hopper-dropper fishing should extend into early October and look for blue-winged olive hatches on the cloudy days.

The Colorado River from Hot Sulphur Springs to Kremmling:

This section is a favorite walk-wade fishing location for the late summer and early fall. The water levels have been staying quite nice and this has been offering some excellent fishing. Look for dry dropper fishing to continue to be successful for some weeks to come and then look to transition to nymphing as the waters cool. Look for blue-winged olive hatches on cloudy days for some excellent dry fly fishing.

The Arkansas River from Granite to Salida:

As late summer and fall approach us, the water levels will start to drop on the upper Arkansas River. When this starts to happen, I will venture farther downstream for higher flows which will give the fish more cover and offer some good hopper dropper fishing for a bit longer than the upper stretches. Get to these lower sections in the weeks to come.

The South Platte above Spinney Reservoir:

With miles and miles of bend after bend of fishing opportunities, the stretches of the South Platte River above Spinney Reservoir can offer some excellent late summer and early fall fishing. Hopper dropper fishing can be excellent for the weeks to come, but it's also a great time of year to strip some streamers along the undercut banks looking for some large resident trout or trout moving up into the river's system out of the reservoir.


Parachute Madam X

This is a favorite low-water and late-season attractor dry fly. This pattern works excellent as the dry in a hopper dropper set up and I also love to fish it in its smaller sizes as a single dry fly or in double dry setups.


If you haven’t fished a Trude, you might give it a try. The white laid-down wing is easy to see and tied in this way the fly can look like many different insects. I have had great success fishing this pattern on many of the rivers in Colorado. Not only does this fly float exceptionally well and is easy to see, but I will sometimes strip and swing this fly in at the end of the drift. With the white wing and the added movement from the swing or strip, this fly can get aggressive strikes using this technique.

Copper John

This go-to standard will start to get used more as we enter the fall months. As we start to see cooler temperatures, smaller insects will start to take over in predominance in the river systems. I will start to use this pattern in its smaller sizes and I specifically like it in its black color.

Zebra Midge

As we enter late summer and early fall midges and smaller nymphs will start to become important to utilize for the weeks to come. Because of this, I will start to use the zebra midge more frequently. This pattern can represent many different insects and with the tungsten bead, it will fish great on dry dropper and nymph setups alike.


With lower flows and sunny skies, the Kreelex shines and it literally does shine with its ample amounts of sparkle. For this reason, I like it on the clear days of late summer and early fall. This is also a great beginner streamer for those of you who are not a fan of the bigger heavier patterns. Not only is this fly easy to cast, but with all the flash, this pattern is very easy to see. Following the fly as you strip it in is part of the fun in streamer fishing and if you get a trout to come swipe at it, you may just be hooked as well as the fish.



As we enter the middle of August, we will continue to see the summer monsoons for the next few weeks. As we get closer to September, look for temperatures to slowly start dropping and that the monsoon pattern to start to exit our region. As we move into September, look for sunny weather but with temperatures starting to drop slightly.
