Efner Lake Brook.

Efner Lake Brook drains into the Great Sacandaga Lake system — a named tributary in a reservoir watershed that reshaped the southern Adirondacks when the Sacandaga was dammed in 1930. The stream itself holds no documented fishery data and sits outside the High Peaks or Wild Forest corridor that draws most backcountry traffic, which typically means private land touches or limited public access. In this part of the Park, streams like Efner Lake Brook are often best understood as hydrological landmarks — named on the map, functional in the watershed, but not necessarily walk-up destinations. Check the DEC's public access atlas if you're targeting tributaries in the Sacandaga drainage.
