Distance, difficulty, rules and camping
DifficultymoderateA 6.5-mile Class I moving-water reach below a major dam. The river is generally recreationally navigable when conditions are suitable, but the dam portage/no-run rule, wood, shallow sections, cold water, and changing commercial traffic demand active judgment.
PermitsNone notedNo route-specific paddling permit is known. Follow Michigan boating rules, posted dam restrictions, and current Croton Township/Newaygo State Park access requirements.
CampingOptions nearbyTreat this as a day route. Use designated Croton-area or Thornapple-area campgrounds only after verifying current season, fees, reservations, and access rules.
SeasonMay-OctLate spring through fall is the practical window. Dam operations, storms, cold water, and seasonal access restrictions can change the route quickly.
