  Ownership and access are not documented in what we hold. Mapping is blank for access, so scout the approach before committing the car. Keep the gear simple: light line, small hooks, split shot and a couple of proven lures. Where the road in crosses private land, ask first. Signs go up and come down, so check on the day. Otter Lake sits 1.4 km off and takes the overflow. Treat Lost Lake as unsettled until someone local tells you otherwise.
