Seneca Lake Fishing in Sublette County, Wyoming

• Overview

  Seneca Lake is listed under Sublette County, Wyoming. Land around it is pine and birch. The water covers some 156 acres, so pick a bank rather than trying to cover it all. Around 3.2 miles of bank, which is a long day on foot. Few waters listed in Sublette County are bigger. Pinedale sits 16 miles from here and is the nearest stop. Fort Washakie follows at 39 miles, then Marbleton at 41 miles. The nearest boundary is well away, so one set of rules covers the water.

• Where to Fish on Seneca Lake

  No published figure covers depth, so learn it as you fish. Look for the band where the shallows give up and the bottom falls away. Weed, then depth: that is the order to fish a water of this kind. Open biodiversity records for Sublette County list brook trout, rainbow trout and brown trout. County records show the wider picture rather than this one place. Read Seneca Lake before you fish it and the day goes better.

• Seasonal Patterns

  Average temperature peaks around 48°F in July and bottoms out near 13°F in January. The middle months are generous; the ends are demanding. Count on hard cover from midwinter, and open water from mid June. Going by climate averages, expect open water from about mid June until roughly late October. September and October fish steadily right up to the freeze. Keep it in mind when planning a trip to Seneca Lake.

• Tackle & Baits

  Nothing we hold confirms whether access is permitted. No dam controls it, and the level follows the season. The map shows no ramp or car park nearby, so this is a walk-in water. Light line and small metal for the trout; a fly rod earns its place on calm evenings. Where the road in crosses private land, ask first. Close seasons apply to some species and not others. Little Seneca Lake sits 1 mile off and takes the overflow. Ask locally about Seneca Lake if anything is unclear.
