Stockport Flats is the northernmost site in the Hudson River Reserve. It is located on the east shore in Columbia County, a few miles north of the city of Hudson, in the towns of Stockport and Stuyvesant.

The Stockport Flats site is a five-mile, narrow mosaic of landforms, including from north to south Nutten Hook, a bedrock outcropping; Gay's Point and Stockport Middle Ground Island, dredge features that are both part of the Hudson River Islands State Park; the mouth of Stockport Creek, a large tributary stream; a portion of the upland bluff south of Stockport Creek; the dredge spoils and tidal wetlands between Stockport Creek and Priming Hook; and the northern end of Priming Hook. The Hudson is entirely tidal freshwater at this site.

Stockport Flats is dominated by freshwater tidal wetlands, including subtidal shallows, intertidal mudflats, intertidal shores, tidal marshes and floodplain swamps.

Stockport Creek drains a watershed of about 500 square miles.
