Turner Lake

Price County, WisconsinMesotrophic

Turner Lake earns a C — middle-of-the-pack water quality, with one or two parameters dragging the average down from a stronger grade. The three sub-grades — clarity, phosphorus, and chlorophyll-a — track close together, so no single parameter is dragging the average.

Mesotrophic conditions dominate at Turner Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. A maximum depth of just 12 ft means sediment-bound phosphorus releases back into the water column whenever wind stirs the bottom — a classic shallow-lake dynamic. At 159 acres, Turner Lake fits the Wisconsin median for monitored lakes, with partial shoreline records. Within Price County's 26 graded lakes, Turner Lake ranks 19 — below the local median, though not at the bottom.

Turner Lake has at least one documented invasive species (Chinese Mystery Snail), so boaters and anglers should observe clean-drain-dry steps when leaving the lake. The fishery includes walleye alongside the lake's other 5 documented species — a notable draw for Wisconsin anglers. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
