Fishing Surprise Lake in Ravalli County, Montana

• Overview

  In Montana, Surprise Lake belongs to Ravalli County. The country here is lake country bush. The water measures roughly 8 acres, so nothing here is far from anything else.

Neighbouring water: Violet Lake 0.4 miles, Buck Lake out at 2.9 miles, Hope Lake 4.9 miles, Mussigbrod Lake out at 5 miles and Continental Lake 5.8 miles. The county line is nowhere near, so one local authority covers the water.

• Where to Fish on Surprise Lake

  Depth remains unrecorded, so treat the first session as a survey. This is a lake, so the margins and the first drop matter most. Read the surface for the wind lane, then fish the edge of it. Species logged across Ravalli County include rainbow trout, cutthroat trout, brook trout and brown trout. Several of these carry legal protection or closed seasons; the rulebook comes before the rod. On Surprise Lake the obvious spot is not always the productive one.

• Seasonal Patterns

  Typical July readings run about 55°F; by December the average is down near 19°F. Winter shuts the surface down for months. Expect a solid lid for months and a thaw around early May. Averages suggest open water from about early May through to roughly mid November. Reckon on open water from spring through to late autumn, with May and June the strongest. That shapes the year on Surprise Lake.

• Tackle & Baits

  Access is not recorded for this water. Public mapping records no formal access here, so plan for a walk and soft ground. For the trout, small spinners and a box of nymphs cover both approaches. Rules differ from one water to the next round here. Close seasons apply to some species and not others. The nearest alternative is Violet Lake, 0.4 miles out.
