The Miami River, accessed from the south end of Lewey Lake, flows through the Adirondack backcountry and is home to wild brook trout. The river is passable for 1 mile upstream from the lake.
Northern pike are sought in the big weedbed where the Miami River enters the lake. Lake trout can be found in the deep waters of mid-lake. Many rocky shorelines attract smallmouth bass.
The river, though not the lake, has a few areas of opportunities for brown trout.
The DEC's Lewey Lake campground, on Route 30, is the only location for a trailer launch on Lewey Lake.
Spring and summer are good times for roadside birding among the wetlands and mixed forest habitats.
There's common loon, belted kingfisher, northern flicker, olive-sided flycatcher, eastern wood pewee, alder flycatcher, least flycatcher, eastern kingbird, northern water thrush, and mourning and Canada warblers.
