Blockhouse Lake Fishing Regulations
Blockhouse Lake follows Wisconsin statewide fishing regulations — no lake-specific special rules in DNR records.
On the scoring rubric Blockhouse Lake grades a D: clarity at 6.0 ft and phosphorus readings still being added keep it in the lower bracket for Price County. Clarity, phosphorus, and chlorophyll-a all rate similarly, so there is no obvious single lever to pull on watershed management.
Eutrophic conditions are the baseline here: clarity drops noticeably in late summer, and dissolved oxygen near the bottom can become a concern. At only 8 ft deep, Blockhouse Lake is shallow — wind keeps the water column mixed and sediment resuspension drives phosphorus levels harder to manage. At 241 acres, Blockhouse Lake fits the Wisconsin median for monitored lakes, with partial shoreline records. Within the 27 graded lakes of Price County, Blockhouse Lake sits at rank 21, near the bottom of the county list.
