Grass Lake in Chisago County: How and When to Fish It

• Overview

  Grass Lake falls in Chisago County, part of Minnesota. Country round the bank runs to mixed forest. Surface area is around 49 acres, which gives you real water without needing a boat. A shoreline of some 1.0 miles keeps the choices simple. It lies lower than most water we list in Minnesota. North Branch at 2.5 miles is the nearest place to stop. Branch lies 4.3 miles off, Harris another 4.8 miles. A county line runs close by, so local bylaws can differ within a short drive.

• Where to Fish on Grass Lake

  Depth here is unknown, so count the lead down before committing. Where the bottom changes texture, fish gather; find that line. The shallow end warms first and pulls fish in ahead of the rest. Across Chisago County, recorded fish include largemouth bass, common carp, bluegill, yellow perch and black crappie. County data is a starting point rather than a guarantee. The shape of Grass Lake rewards a slow walk along one bank.

• Seasonal Patterns

  Average temperature peaks around 70°F in July and bottoms out near 10°F in January. Fishing here follows the temperature more than the calendar. The lid usually goes in early April, which opens the strongest weeks of the year. In an average year the thaw lands around early April and the freeze near late November. Reckon on open water from spring through to late autumn, with May and June the strongest. Time your trip to Grass Lake by conditions rather than dates.

• Tackle & Baits

  Whether the bank is open is not something our records settle. This is a natural basin, not a dammed one. Expect 0.9 miles away in from where the car goes. A small crankbait along the drop and a worm in the thick stuff cover the bass. Look for a notice board at the entrance. Some stretches are reserved and marked as such on the ground. Mud Lake sits 0.6 miles off and takes the overflow. Signs at Grass Lake carry more weight than any list.
