Lower Lawrence Lake

Lower Lawrence Lake earns a D — measurements through 2024 show persistent nutrient pressure that limits clarity through the summer. Sub-grades cluster within a single letter of each other, which usually means the lake is in stable trophic balance rather than fighting one specific stressor.

At a TSI of 55, Lower Lawrence Lake reads as eutrophic — nutrient-rich enough that summer algal growth and reduced clarity are expected, not unusual. A maximum depth of 34 ft puts Lower Lawrence Lake in the middle of Minnesota's depth distribution. At 152 acres, Lower Lawrence Lake fits the Minnesota median for monitored lakes, with 3.2 miles of shoreline. Lower Lawrence Lake ranks 129 of 141 in Itasca County — at the lower end of the locally monitored distribution.

Lower Lawrence Lake has no invasive species recorded in Minnesota state databases as of 2024, though prevention practices still apply at all access points. The state fisheries records do not list documented species for Lower Lawrence Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. No formal public access is documented at Lower Lawrence Lake — most use is by shoreline residents and their guests. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
