State Ranking Justification [-]
Historically occurring in about 36 waters, Iowa darters are currently found in about 17 waters scattered throughout the St. Lawrence, Lake Ontario, and Lake Erie watersheds. Historical populations in Oneida Lake and nearby streams and creeks in Oswego County, and Black Lake in St Lawrence County have not been recorded since the 1930s (Carlson 2005; Cohen 2006; New York Natural Heritage Program 2008). More sampling is needed to determine the current status of Iowa darters in New York (Carlson 2005; Cohen 2006).
