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, 30% survey rate, and 10% recency, plus 5% for a current species report. 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 largemouth bass ranking.
FAQ
2 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 Polk County.
54 Polk County lakes have a DNR largemouth bass status record. Numeric rank still requires an exact comparable family plus the acreage and access gates.
