• Overview

  Finn Reservoir stands in Valley County, Montana. The surface lies 2,638 feet up. The water measures roughly 8 acres, so nothing here is far from anything else. It is low-lying compared with other Montana water we list. Glasgow lies 32 miles from the water. For a city, Billings is 160 miles off. It lies deep inside the county rather than near an edge.

• Where to Fish on Finn Reservoir

  Depth here is unknown, so count the lead down before committing. The arms fish better than the open middle whenever the water is up. Standing timber shows when the level drops, and fish sit against it. Across Valley County, recorded fish include Chinook salmon, northern pike, cisco and walleye. Some of the species recorded here are protected or tightly regulated, so check what may be targeted before you fish. The shape of Finn Reservoir decides where the fish sit.

• Seasonal Patterns

  Temperature averages peak at 71°F in July and bottom out at 16°F in January. Cold locks it up for a good stretch each year. Look for the thaw near early April; the fishing lifts straight after. Open water usually runs from early April until about late November. The middle of summer slows a little, with dawn and dusk carrying it. Finn Reservoir runs to its own calendar within the local pattern.

• Tackle & Baits

  Nothing in our records says who may fish here. No made access is recorded, so a short walk in is the likely arrangement. Bass water: a Texas-rigged worm near cover, a spinnerbait when you need to cover ground. Season dates differ by species, so read the table. Keep proof of licence with you rather than in the car. Ruins Reservoir sits 0.5 miles off and takes the overflow. Signs at Finn Reservoir carry more weight than any list.
