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.

FAQ
Cass County largemouth bass fishing FAQ Which largemouth bass lakes receive a numeric county rank? 21 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 Cass County.
How many Cass County lakes have largemouth bass? 34 Cass County lakes have exact-water DNR survey evidence. Numeric rank still requires an exact comparable family plus the acreage and access gates.
