[3] The marshlands through which Oak Orchard Creek flows are a major stopover points for migratory birds, and are protected by state- and federally-designated conservation areas.

[4] The swamp is a result of a partial blockage of the river by glacial drift and an outcrop of limestone and dolomite known as the Lockport Formation which forms the Niagara Escarpment.

The lower part of the creek remains relatively ice-free during winters presumably due to steady flow of water and hydro-plant at Waterport.

Boating is limited to a short distance upstream from a point called Toms Landing due to the shallow depth.

The state fish hatcheries release brown trout, salmon and steelhead each year into the river.
