Methodology
How this list is built
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.
