90-Day Finding on a Petition To List the Upper Tidal Potomac River Population of the Northern Water Snake (Nerodia sipedon) as an Endangered Distinct Population Segment

We, the U.S. Fish and Wildlife Service (Service), announce a 90-day finding on a petition to list the distinct vertebrate population segment (DPS) of the northern water snake (Nerodia sipedon) in the upper tidal Potomac River as endangered under the Endangered Species Act of 1973, as amended (Act). We find the petition does not provide substantial scientific or commercial information indicating that the petitioned action is warranted. Therefore, we will not initiate a further status review in response to this petition. We ask the public to submit to us any new information that becomes available concerning the status of this population of the northern water snake or threats to it.
