REFERENCE INTERNAL NPS ONLY WITH HOLDING RESTRICTED TO SPECIFIC INDIVIDUALS - PROTECTED DATA The federally endangered dwarf wedgemussel, Alasmidonta heterodon, requires certain habitat conditions for survival, which may include specific temperature and flow regimes. Dewatering caused by chronic drought and increased water demands of the New York City metropolitan area may threaten A. heterodon populations in the National Park Service Upper Delaware Scenic and Recreational River (UPDE) by reducing flow levels and increasing water temperatures, particularly during summer months. This study evaluated the discharge and temperature relationships between mainstem Delaware River USGS gages and three known A. heterodon locations in order to develop models that will assist managers in preventing detrimental impacts to mussels.
