Chisago County, Minnesota, is where Lake Mattson sits. Country round the bank runs to lake country bush. Surface area is around 43 acres, which gives you real water without needing a boat. A shoreline of some 1.6 miles keeps the choices simple. By elevation it sits in the lower part of our Minnesota listings. For supplies, Chisago City is 1.4 miles out. Lindstrom is 2.3 miles away, with Stacy at 4.5 miles. The nearest boundary is a fair way off.
Depth figures are not published for this one. A soft bed grows weed late into autumn, which keeps fish shallow. The productive water is a rod length or two out, not a hundred. Public occurrence data for Chisago County names largemouth bass, common carp, bluegill, yellow perch and black crappie. It is the county picture; the agency list is water-specific. At Lake Mattson the water rewards a slow, careful approach.
Averages move between 11°F in January and 71°F in July. The middle months are generous; the ends are demanding. The freeze runs deep into the year, with break-up near early April. Break-up sits around early April on average, with the water closing again about late November. Look to early summer and the first cool weeks of autumn. On Lake Mattson the same rules apply, with local timing.
Nothing we hold confirms whether access is permitted. No dam controls it, and the level follows the season. No slipway, car park or made path shows up nearby in mapping, so treat access as rough. Largemouth respond to soft plastics tight to cover; go weedless where the growth is heavy. Check whether a boat is allowed before you tow one. Signs go up and come down, so check on the day. Failing this one, try School Lake, 0.6 miles away. Nothing on Lake Mattson should be assumed from this page alone.
