Top 5 Utah Rivers Fishing This Week | December 2025

The Green River Section A was flowing on the report date at 854 cfs (normal) with a stable trend. Flows were rated fishable on the report date. Water Temperature: 43°F (cold). The Verdict: Excellent Fishing Conditions This week’s forecast shows temperatures ranging from 27-45°F. Calm winds make subtle nymph takes easier to detect.

Insect Activity: Dam releases create stable tailwater conditions ideal for winter fishing. Midges and small nymphs remain active throughout the season, with streamer patterns effective in deeper runs.

Fishing approach: Study deeper runs and tailouts from a confirmed legal fishing position. Adjust depth and weight to the drift you can reach without an uncertain crossing.

Gear Tip: Start with a two-fly nymph rig and a yarn indicator. A 9-foot 5X leader with light tippet keeps the rig natural in winter flows.

Presentation: Dead-drift the nymph rig through slower seams and focus on the warmest part of the day. Add just enough weight to tick bottom every few drifts.

The Green River Section B was flowing on the report date at 854 cfs (normal) with a stable trend. Flows were rated fishable on the report date. Water Temperature: 43°F (cold). The Verdict: Excellent Fishing Conditions This week’s forecast shows temperatures ranging from 28-46°F. Calm winds make subtle nymph takes easier to detect.

Insect Activity: Consistent tailwater temperatures support year-round insect activity. Midges and small nymphs are key patterns, while streamer fishing can be productive when targeting larger fish.

Fishing approach: Look for reachable seams beside slower water. A controlled nymph drift can cover the holding lane without moving farther into the current.

Gear Tip: Start with a two-fly nymph rig and a yarn indicator. A 9-foot 5X leader with light tippet keeps the rig natural in winter flows.

Presentation: Dead-drift the nymph rig through slower seams and focus on the warmest part of the day. Add just enough weight to tick bottom every few drifts.

The Verdict: Excellent Fishing Conditions This week’s forecast shows temperatures ranging from 27-45°F. Calm winds make subtle nymph takes easier to detect.

Insect Activity: Tailwater conditions maintain consistent insect activity year-round. Midges and small nymphs are the primary insects active, with streamer fishing providing additional opportunities.

Fishing approach: Watch the pool edges before casting. Use a longer presentation when moving closer would disturb fish or require an uncertain route.

Gear Tip: Start with a two-fly nymph rig and a yarn indicator. A 9-foot 5X leader with light tippet keeps the rig natural in winter flows.

Presentation: Dead-drift the nymph rig through slower seams and focus on the warmest part of the day. Add just enough weight to tick bottom every few drifts.

Insect Activity: Dam releases create stable tailwater conditions ideal for winter fishing. Midges and small nymphs remain active throughout the season, with streamer patterns effective in deeper runs.

Fishing approach: Fish current breaks and shaded structure from an authorized position. Match the fly and presentation to the activity you observe.

Gear Tip: Start with a two-fly nymph rig and a yarn indicator. A 9-foot 5X leader with light tippet keeps the rig natural in winter flows.

Presentation: Dead-drift the nymph rig through slower seams and focus on the warmest part of the day. Add just enough weight to tick bottom every few drifts.

The Currant Creek Below Reservoir was flowing on the report date at 17 cfs (normal) with a falling trend. Flows were rated fishable on the report date. The Verdict: Good Fishing Conditions This week’s forecast shows temperatures ranging from 24-42°F. Calm winds make subtle nymph takes easier to detect.

Insect Activity: Tailwater conditions maintain consistent insect activity year-round. Midges and small nymphs are the primary insects active, with streamer fishing providing additional opportunities.

Fishing approach: Give a promising seam several controlled drifts, then change depth or pattern. Moving farther along the bank requires a separately confirmed route.

Gear Tip: Start with a two-fly nymph rig and a yarn indicator. A 9-foot 5X leader with light tippet keeps the rig natural in winter flows.

Presentation: Dead-drift the nymph rig through slower seams and focus on the warmest part of the day. Add just enough weight to tick bottom every few drifts.
