1st Street S, aka Birch Street, aka Hwy.182

From satellite/aerial views, this highway/street bridge appears to have some sort of 'disruption' of the flow. It is not apparent (and we have no first-hand or second-hand info) whether this is from a bridge-pier/footing or from a natural riverbed feature (creating a wave or hole). Thus, your preferred take-out (whether upstream of the bridge or downstream of it) may depend upon actual flow, best eddies, best shoreline access, and whether there is any interest/play below this bridge.

Interesting ... west of the river, in downtown Park Falls, the main East-West street is Division Street, and all other streets are numbered consecutively BOTH North and South from there! (1st street North, 2nd Street North, ..., AND 1st street South, 2nd Street South, ....) However, East of the river, the East-West streets have (non-numeric) names; Wisconsin Street 'matches' to Division, and virtually all other East-West streets are tree names (Birch, Pine, Maple, Cedar, etc).
