Overnight Reservoir

Overnight Reservoir is a reservoir in Beaverhead County, Montana.

Without a dependable size figure for Overnight Reservoir, weeds, rock, water color, and nearby depth are the best starting clues.

Fish and Baits

Around the outside edge of a gravel shelf, the fish mix here is not confirmed, so check fresh local information before choosing a target or keeping a catch.

Near the outside edge of the first drop, begin with one slow bottom presentation and one moving bait, then let bites show whether fish are holding close to cover or roaming open water.

How to Read the Water

Across the open side of a narrow arm, start where two things meet: weeds and open water, rock and mud, a point and a drop, or clear water and dirty water; fish that edge at more than one depth before leaving it.

Season by Season

Across the channel lip of the nearest cove, early in the year, protected water and the first warm afternoon can be the best clues; as the water heats up, check deeper edges without assuming every fish is on the bottom; cooling fall water often makes points and firm banks useful again.

A Simple Tackle Plan

Beside the quiet end of a channel turn, a medium spinning rod, 8-pound line, a small box of jigs, a few crankbaits, and a simple bottom rig cover most situations; change depth or speed before changing every piece of tackle.

Across the shaded side of the first drop, record the wind, water color, depth where the bait worked, and cover after a bite; those four notes are more useful on the next trip than a long list of spots that did not produce.
