Last Reservoir Fishing Guide, Valley County, Montana

• Overview

  Last Reservoir falls in Valley County, part of Montana. Everything around it is sage and rock. The water measures roughly 3 acres, so nothing here is far from anything else. Ground here is low by Montana standards. Glasgow sits 12 miles from here and is the nearest stop. Billings sits 176 miles out, and it is the nearest city worth the name. This one is safely inside the county line.

• Where to Fish on Last Reservoir

  Depth is not on record here, so the bank has to tell you. The old creek line under the surface is the feature worth finding. Rip-rap along the wall holds fish that the open bank never does. Reported across Valley County: Chinook salmon, northern pike, cisco, walleye and yellow perch. Some of the species recorded here are protected or tightly regulated, so check what may be targeted before you fish. Anyone new to Last Reservoir should walk it once before setting up.

• Seasonal Patterns

  July runs about 72°F on average, January about 13°F. Cold winters and warm summers give a wide working range. Break-up comes around early April, and the run that follows is short and strong. From about early April to around late November, expect open water on the long-run figures. Late spring and early autumn carry the year between them. Expect Last Reservoir to follow that timing.

• Tackle & Baits

  Public sources are silent on who controls the bank. There is no mapped parking or launch nearby, which keeps numbers down. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. Read any posted signs at the access point rather than assuming. Where the way in crosses private ground, ask first. The nearest alternative is VR-105 Reservoir, 1.4 miles out. Rules at Last Reservoir are worth checking on the day.
