Note: This report is a part of the FlyCast Lite reporting program and is updated seasonally or in the event of substantial changes that alter fly fishing tactics. FlyCast Lite reports are intended to give anglers a high level overview on seasonal conditions and general fishing tactics.

Flows at Tarryall Creek have trended down over the last few months and are sitting slightly below the historical average for this time of year. Dry droppers continue to produce the best results. If you go this route, lead with a small attractor dry fly like an Elk Hair Caddis, Micro Chubby Chernobyl, Amy's Ant or Hippie Stomper. Trail any of these flies with 12 to 18 inches of tippet (or 1.5X the depth of the water) followed by one or more smaller nymphs. Guide's Choice Hare's Ears, Flashback PTs, Rainbow Warriors and red Copper Johns are all productive droppers. Otherwise, trail any of the aforementioned flies with smaller midge or baetis larva/emergers. Make sure to give most of your attention to the grassy banks, but don't forget to pick apart the seams and pocket water. Otherwise, surface action has been productive as well, so keep an eye out for rising trout during midge and BWO hatches.

Detailed River Info

Background

Tarryall Creek originates at roughly 11,500 ft on Mount Silverheels and flows southeast into South Park where it meets a number of feeder creeks, most notably Michigan and Jefferson Creek. From South Park, it flows a little over 20 miles into Tarryall Reservoir. Upstream of the reservoir, Tarryall runs through open meadows and predominantly private grazing land. Just below the Tarryall Dam and diversion, the landscape is largely the same. However, it quickly approaches a heavily wooded canyon and steep granite walls. Tarryall Creek offers a variety of small to medium sized rainbow and brown trout, but there are certainly a few lunkers in the 18 to 20 inch variety. Additionally, it is not uncommon to come across wandering pike in the creek on either side of the reservoir.

Angling

The broader Tarryall Creek is most accessible from late spring through early winter. However, the tailwater section below the dam can be fished most of the year. That being said, low winter flows and harsh weather will leave most of the river iced over. In the summer, come prepared with some bug spray as the mosquitos can be relentless. While the nymph rig will produce in the colder months, the dry dropper is our preferred method of fishing most of the year and is particularly effective in the summer and fall. Trout here are not terribly selective and typically have eyes bigger than their stomachs. Meaning, little trout are not shy to hoppers that are half their size.Hatch activity is great particularly in the summer and fall. You can expect to see midges year round as well as BWOs from March to Nov. In the summer and fall, you can expect to see terrestrials, tricos, PMDs, stoneflies and caddis. Small streamers are a solid option too, but can be hit or miss.

River Access

While access is very limited, there are a number of public walk-ins above and below Tarryall Reservoir. Upstream of the reservoir, there are a couple walk-in access points that are clearly marked, one of which is the Tarryall Reservoir State Wildlife area which is about 2 miles northwest of the reservoir. Otherwise, below the dam, there is a quarter mile stretch of public water that offers easy and clear parking. Further southeast, on Highway 77, most of the water is private. However, there are a number of walk-in points at the Ute Creek Trailhead, at the Twin Eagles picnic area/campground and at the Spruce Campground. Beyond that, you enter Pike National Forecast land, but access is difficult. That being said, if you’re up for some “offroading” (4X4 or ATV) and looking for a hike (~2 miles), Forest Road 210 will take you to a trail system where you can access some low pressured water near the confluence of the South Platte.
