Methodology
County ranks use the same statewide exact-family contract; systems with at least two eligible county peers restart at #1. The score is 55% survey rate × acreage, 35% survey rate, and 10% recency. Catch-per-effort × acreage is only an opportunity index, never a literal fish count. Documented acreage plus verified public or shore access are eligibility gates. Unsupported methods stay documented but unranked. See the complete definitions on the statewide musky ranking.
FAQ
0 lakes receive at least one peer-backed, exact-lake numeric rank. Catch-per-effort systems separate species, phase, gear, unit, and sampled population; standardized adult-density estimates form their own system, so systems with at least two eligible county peers can each have a #1 in Cook County.
3 Cook County lakes have exact-water DNR survey evidence. Numeric rank still requires an exact comparable family plus the acreage and access gates.
