Fishing Report September 15th - 21st, 2025

Northern Utah Fishing Report | September 15–21, 2025

As fall approaches, cooler nights are changing the fishing patterns across Northern Utah. Trout are feeding heavier in rivers, and the reservoirs are slowly shifting into autumn behavior. Whether you’re chasing trout on moving water or targeting warmwater species on the lakes, this week offers some of the most consistent fishing of the season.

Lost Creek Reservoir

Lost Creek is one of the most reliable late-summer trout destinations right now. The cooler temps have the rainbows and cutthroats cruising close to the surface early and late in the day.
Water Conditions: Clear with visibility around 8–10 feet. Surface temperatures are sitting in the mid-60s.
What’s Working: Small olive leeches, zebra midges, and chironomid patterns have been productive under an indicator. Trolling spoons or small crankbaits in 10–20 feet of water is also picking up some solid fish.
Times to Go: Early morning and late evening are best, especially when the water is calm.
Species: Rainbow trout and cutthroat trout.

Pro Tip: Don’t overlook slow retrieves — the fish are active but selective as the turnover nears.

Logan River

The Logan River continues to fish well with stable flows and dropping water temperatures. It’s a great time to target wild browns in the upper stretches.
Flows & Conditions: Clear and cool, perfect for wading. The upper canyon is especially active right now.
What’s Working: Nymphing with small perdigons, hare’s ears, and zebra midges has been consistent. Afternoon dry-fly action is heating up with caddis and small mayflies hatching.
Times to Go: Midday to early evening.
Species: Brown trout and rainbow trout.

Shop Tip: Keep your presentation light — these fish can get spooky in the clear water.

Echo Reservoir

Echo is holding steady and remains a great option for both trout and bass anglers. Water levels are moderate, and clarity is improving after recent storms.
Water Conditions: Slightly stained with temps in the upper 60s.
What’s Working: For trout, try trolling with small spinners or casting spoons near the dam. Bass anglers should focus on structure and use drop-shot rigs or Ned rigs along rocky shorelines.
Times to Go: Early morning or late evening has been most productive.
Species: Rainbow trout, smallmouth bass, and perch.

Pro Tip: As temperatures cool, fish are starting to move shallower — target points and coves near deeper water transitions.

Pineview Reservoir

Pineview continues to produce steady action for warmwater species. Tiger muskie are showing more interest as the water cools, and bass are feeding up before fall turnover.
Water Conditions: Visibility is fair; temps are in the upper 60s to low 70s.
What’s Working: Topwater baits early, followed by soft plastics and spinnerbaits as the sun rises. Large glide baits and jerkbaits are moving muskie in the morning hours.
Times to Go: Dawn to mid-morning and again near dusk.
Species: Tiger muskie, largemouth bass, smallmouth bass, and crappie.

Pro Tip: Focus on shaded areas and submerged structure — predators are ambushing baitfish in tighter cover now.

Final Thoughts

Northern Utah fishing is only getting better as the weather cools down. Trout are feeding heavier in rivers like the Logan, while the reservoirs — especially Lost Creek and Echo — are entering their prime. Pineview remains a solid pick for those chasing big warmwater fish.
