About Mad River
The Mad River is Ohio's most celebrated inland trout stream — a spring-fed freestone river that originates from cold limestone springs near Zanesfield in Logan County. Unlike virtually every other central Ohio river, the Mad's groundwater-fed source keeps it cold enough for wild brown trout year-round despite sitting in the agricultural flatlands. Ohio DNR stocks 10,000–15,000 brown trout fingerlings annually; holdover fish regularly reach 14–16 inches, with occasional larger specimens. The West Liberty gauge captures the prime fishing stretch from Zanesfield downstream through Logan County. Flows are remarkably stable (typical spring-fed baseline around 20–60 CFS) — rain events can push it to 100–150 CFS temporarily but it drops fast. Year-round trout season; no special C&R regulations as of 2026 regs. Best hatches: Sulphurs, Cahills, caddis (March–November).
Regulations
Ohio fishing license required (resident $25/year). Year-round trout season; no special catch-and-release regulations on the Mad River as of 2026–27 regs. 2026–27 regulation cycle effective March 1, 2026. Verify at wildohio.gov.
