Bag and size limits, seasons, and license requirements for fishing in Utah, across 5 spots tracked by FishRadar. Informational only — confirm the current rules with the official authority before you fish.
| Species | Bag limit | Min size | Open season |
|---|---|---|---|
| Rainbow TroutDaily limits | 4/day | — | Jan 1 – Dec 31 |
| Four fish COMBINED across trout, kokanee salmon and Arctic grayling — not four of each. At Flaming Gorge Reservoir the limit is 4 trout or kokanee combined excluding lake trout, of which no more than 3 may be kokanee. | |||
| Brown TroutDaily limits | 4/day | — | Jan 1 – Dec 31 |
| Four fish COMBINED across trout, kokanee salmon and Arctic grayling — not four of each. Several of Utah's named trout waters, including stretches of the Provo and Green rivers, carry stricter water-specific rules; check the Rules for specific waters section of the guidebook. | |||
| Lake TroutRules for specific waters — Flaming Gorge Reservoir, Daggett County | 4/day | — | Jan 1 – Dec 31 |
| Lake trout fall inside the statewide 4-fish combined trout limit. FLAMING GORGE IS THE EXCEPTION AND IS MORE GENEROUS: no limit on lake trout of 28 inches or less, and only 1 lake trout may exceed 28 inches. Dead lake trout that are part of the daily bag may be used as bait there. | |||
| Kokanee SalmonDaily limits | 4/day | — | Dec 1 – Sep 9 |
| Kokanee are part of the combined 4-fish trout limit, not a separate allowance. ANGLERS MAY NOT POSSESS KOKANEE SALMON AT ANY WATERBODY STATEWIDE FROM 10 SEPTEMBER THROUGH 30 NOVEMBER. At Flaming Gorge no more than 3 of the 4 combined fish may be kokanee. | |||
| Largemouth BassDaily limits | 6/day | — | Jan 1 – Dec 31 |
| Six fish COMBINED with smallmouth bass. At Flaming Gorge the combined bass limit is 3. On community fisheries the total limit is 2 fish of most species and anglers are encouraged to release all largemouth bass. | |||

| Six fish COMBINED with largemouth bass. At Flaming Gorge the combined bass limit is 3. | |||
| Striped BassDaily limits | — | — | Jan 1 – Dec 31 |

| WalleyeDaily limits | 10/day | — | Jan 1 – Dec 31 |
| Ten fish daily, of which ONLY ONE MAY EXCEED 24 INCHES. That over-size cap is not a minimum size and is not shown in the size column. | |||
| Channel CatfishDaily limits | 8/day | — | Jan 1 – Dec 31 |
| Eight fish daily statewide; at Flaming Gorge the catfish limit is 6. | |||
| White BassDaily limits | — | — | Jan 1 – Dec 31 |
| NO DAILY LIMIT statewide. | |||
| Common CarpDaily limits | — | — | Jan 1 – Dec 31 |

Licensing:
FishRadar regulations are summaries for informational purposes only. The figures here are the Utah STATEWIDE daily limits from the 2026 Utah Fishing Guidebook; the guidebook itself warns that specific bag or size restrictions apply on many waters. Lake Powell, Flaming Gorge and Bear Lake are shared with neighbouring states under reciprocal licence agreements — you must follow the rules of the state whose water you are actually fishing, and you may take only one daily limit per day. Always check the Rules for specific waters section before you fish.
