Unnamed Rusk Co -Deep Hole Lake
Rusk County, WisconsinMesotrophic
On the LakeGrade scale Unnamed Rusk Co -Deep Hole Lake grades a B, with clarity at 18.6 ft and 31 µg/L of phosphorus placing it above the Wisconsin median. High phosphorus is the leading drag on the score — likely from upland agriculture, lawn runoff, or in-lake sediment release.
Mesotrophic conditions dominate at Unnamed Rusk Co -Deep Hole Lake: enough nutrients for a healthy fishery, not so much that algal blooms become a chronic problem. Unnamed Rusk Co -Deep Hole Lake reaches 16 ft at its deepest point — typical for Wisconsin mid-sized lakes, with seasonal stratification but limited cold-water refuge. Unnamed Rusk Co -Deep Hole Lake is small — 7 acres alongside partial shoreline records — which makes it sensitive to even modest changes in watershed runoff or recreational pressure. Unnamed Rusk Co -Deep Hole Lake ranks 10 of 13 in Rusk County — at the lower end of the locally monitored distribution.
Unnamed Rusk Co -Deep Hole Lake has no invasive species recorded in Wisconsin state databases as of 2022, though prevention practices still apply at all access points. The state fisheries records do not list documented species for Unnamed Rusk Co -Deep Hole Lake, which usually reflects a lack of formal fisheries survey work rather than an empty lake. The grade is based on limited monitoring — fewer than three independent measurement years contribute, so future updates may shift the letter.
