About Provo River

The Provo River in Utah has three distinct sections, but the Middle Provo between Jordanelle Dam and the mouth of Provo Canyon is the most celebrated tailwater. Cold releases from Jordanelle Reservoir maintain water temperatures year-round in this section. The Middle Provo is designated as special regulation water with catch-and-release and artificial flies and lures only, protecting a high-quality wild trout population.

Wild rainbow and brown trout populate the Middle Provo, and the river is known for producing trophy brown trout. Fish in the 18 to 24-inch range are caught regularly throughout the season. US-189 through Provo Canyon provides good access to most of the Middle Provo stretch, though some sections require a short walk. Wading is manageable in most flows but technical in the boulder sections of the canyon.

Midges are active year-round on the Provo, providing consistent winter fishing when other rivers are blown out. BWOs hatch from March through November, with April and October being the peak months. PMDs and caddis overlap in summer for productive dry fly action. The Trico spinner fall in August brings selective fish to the surface in the smoother flat sections. Autumn Caddis in September and October closes out the main hatch season.

The Provo is highly accessible from both Salt Lake City and Provo, drawing consistent angling pressure throughout the year. The Middle Provo section near the Hailstone access point sees the most traffic. Moving upstream toward the dam or fishing weekday mornings reduces competition. Fall and winter are the best seasons for less-pressured fishing on this storied river.

What to Fish

Provo River Key Hatches

Blue-Winged Olive

March through May, September through November

Baetis sp.

BWOs on the Provo are among the most reliable hatches in the state. They run from early spring into late fall, with April and October being the peak months. Overcast days in Provo Canyon trigger dense emergences in the smooth flats and pool tails. Fish here are selective due to consistent pressure. A low-riding Sparkle Dun or CDC Dun in size 18 to 22 and 6X tippet handles most rising fish during BWO windows.

Recommended: Sparkle Dun, CDC Dun #18-22

PMD

May through August, peak June and July

Ephemerella infrequens

PMDs are the signature summer hatch on the Provo. June and July produce the most consistent emergences in the canyon. Morning hatches draw fish up in the flat sections below Jordanelle. Spinner falls in late afternoon can bring the largest fish in the river to the surface for a brief window. Fish the smooth water with size 16 to 18 Comparaduns and 5X or 6X tippet. The PMD overlaps with caddis in June for some of the best dry fly days of the year.

Recommended: PMD Sparkle Dun, Comparadun #16-18

Midge

Year-round, peak February and December

Chironomidae

Midges keep the Provo fishing year-round. Winter midge fishing from November through February is the most productive time for large brown trout in the Middle Provo. Dense winter emergences bring fish to the surface in the flat sections on warmer days. A Zebra Midge or RS2 in size 20 to 26 fished under an indicator covers most midge situations. This is technical fishing requiring light tippet and patience.

Recommended: Zebra Midge, RS2 #20-26

Common Questions

Provo River Fly Fishing FAQ

Where is the best section of the Provo River for fly fishing?

The Middle Provo between Jordanelle Dam and the mouth of Provo Canyon is the best section. It is designated as catch-and-release only with artificial flies and lures. Access is available from US-189 through the canyon. The Hailstone area near Jordanelle has good access and parking. Sections near the dam produce the coldest water and are often the most productive in summer.

What size fish can I expect on the Provo River?

The Provo River Middle Section regularly produces rainbow and brown trout in the 14 to 20-inch range. Trophy brown trout over 20 inches are caught throughout the year, particularly in fall and winter. Fish average somewhat larger than most Utah freestone streams due to the tailwater environment and catch-and-release regulations. The biggest fish tend to hold in the deeper pools and undercut banks.

When is the best time to fish the Provo River?

Fall from September through November and winter from December through February are the best times for large brown trout and less pressure. Spring BWO hatches in April are excellent for dry fly fishing. June through July offers the most diverse hatch activity with PMDs, caddis, and other species. Summer mornings before the canyon warms up produce the best midsummer results.
