Dean Creek (Cayuga Lake tributary)

Dean Creek is a small stream located in the Finger Lakes region of New York State. It is a tributary of Cayuga Lake, the longest of the eleven Finger Lakes. The creek's watershed is primarily agricultural and forested, draining a portion of the land west of Cayuga Lake.

Dean Creek flows generally eastward, eventually emptying into Cayuga Lake along its western shore. The creek's specific location of entry into the lake is typically north of the village of Trumansburg. Due to agricultural runoff in its watershed, Dean Creek may experience elevated levels of nutrients and sediment. Local environmental groups and governmental agencies may monitor the water quality of Dean Creek and implement best management practices to reduce non-point source pollution. The creek is often mentioned in studies related to Cayuga Lake's overall water quality and ecological health.
