Square Lake near Sisters: Fishing Spots, Seasons and Access

• Overview

  Look for Square Lake in the Jefferson County part of Oregon. The surroundings are mixed woodland. At about 50 acres, a day is enough to walk the shoreline properly. Sisters sits 17 miles from here and is the nearest stop. It is 68 miles to Eugene, the nearest city. It lies deep inside the county rather than near an edge.

• Where to Fish on Square Lake

  Nothing we hold settles how deep this runs. The shallow end warms first and pulls fish in ahead of the rest. The productive water is a rod length or two out, not a hundred. Records held for Jefferson County cover rainbow trout, bull trout and smallmouth bass. Some of the species recorded here are protected or tightly regulated, so check what may be targeted before you fish. Square Lake fishes better once you know its edges.

• Seasonal Patterns

  The warm month here averages 58°F; the cold one sits at 28°F. Whether it freezes depends on the year. Hard water here is never dependable, so check for yourself before stepping out. November and March are the quiet, comfortable months to be out. Expect Square Lake to follow that timing.

• Tackle & Baits

  Nothing we hold confirms whether access is permitted. Public mapping records no formal access here, so plan for a walk and soft ground. For the bass here, soft plastics worked slow along cover and a spinnerbait for searching do most of the work. Bank access can be seasonal on ground like this. Rules for boats are stricter than rules for the bank in many places. For a change of water, Long Lake is 0.7 miles distant. Check the position on Square Lake before loading the car.
