Juergens Lake

Juergens Lake earns a D — measurements through 2025 show persistent nutrient pressure that limits clarity through the summer. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.

At a TSI of 59, Juergens Lake reads as eutrophic — nutrient-rich enough that summer algal growth and reduced clarity are expected, not unusual. The lake bottoms out at 22 ft — a moderate depth that supports a warm-water fishery without the year-round cold refuge a deeper basin provides. At 117 acres, Juergens Lake fits the Minnesota median for monitored lakes, with 2.3 miles of shoreline. Within the 18 graded lakes of Todd County, Juergens Lake sits at rank 18, near the bottom of the county list.

Juergens Lake is on the Minnesota infested-waters list for zebra mussels — boaters should follow clean-drain-dry protocols when moving gear to or from the lake. The fishery is bass-led, with 6 documented species across the lake's records. No formal public access is documented at Juergens 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.
