2014 Aquatic Invasive Species Surveys of New York City Water Supply Reservoirs Within the Catskill/Delaware and Croton Watersheds
2014 aquatic invasive species surveys of New York City water supply reservoirs within the Catskill/Delaware and Croton Watersheds Megan Wilckens1, Holly Waterfield2 and Willard N. Harman3 INTRODUCTION The New York City Department of Environmental Protection (DEP) oversees the management and protection of the New York City water supply reservoirs, which are split between two major watershed systems, referred to as East of Hudson Watersheds (Figure 1) and Catskill/Delaware Watershed (Figure 2). The DEP is concerned about the presence of aquatic invasive species (AIS) in reservoirs because they can threaten water quality and water supply operations (intake pipes and filtration systems), degrade the aquatic ecosystem found there as well as reduce recreational opportunities for the community. Across the United States, AIS cause around $120 billion per year in environmental damages and other losses (Pimentel et al. 2005). The SUNY Oneonta Biological Field Station was contracted by DEP to conduct AIS surveys on five reservoirs; the Ashokan, Rondout, West Branch, New Croton and Kensico reservoirs. Three of these reservoirs, as well as major tributary streams to all five reservoirs, were surveyed for AIS in 2014. This report details the survey results for the Ashokan, Rondout, and West Branch reservoirs, and Esopus Creek, Rondout Creek, West Branch Croton River, East Branch Croton River and Bear Gutter Creek. The intent of each survey was to determine the presence or absence of the twenty- three AIS on the NYC DEP’s AIS priority list (Table 1). This list was created by a subcommittee of the Invasive Species Working Group based on a water supply risk assessment. -

The 6-megawatt facility will generate enough renewable electricity to power more than 3,500 homes annually by harnessing the force of water that is Drinking Water continuously released downstream of the reservoir. DEP expects to complete the Wastewater 4,400-square-foot hydroelectric facility by 2025. Stormwater The revised proposal follows a 2015 engineering assessment at the site, which Harbor Water found an artesian aquifer downstream of Cannonsville Dam. Initial plans for a 14- Long Term Control Plan megawatt facility, including a 9,000-square-foot powerhouse, were deemed infeasible after the initial examination of conditions at the site. For more than two years, DEP has worked with experts to study the aquifer and develop a revised plan for generating clean energy at the site. Watershed Protection “DEP is proud to announce a project that continues to expand the amount of clean Watershed Recreation energy produced by our vast water supply system,” DEP Commissioner Vincent Sapienza said. -

Intensive monitoring at the site will continue as DEP resumes normal operations Watershed Protection at Cannonsville Reservoir. These efforts will include 24-hour observations by on- Watershed Recreation site staff and surveillance cameras, daily engineering inspections, and near real- time monitoring of turbidity and safety instruments inside Cannonsville Dam. Although DEP is resuming normal drinking water and release operations, reservoir storage will likely continue to decline because the amount of water Regulatory Reform naturally flowing into the reservoir is generally less than the amount of water Environmental Education released to the river during summer. -
