The Federal The U.S. Army Corps of Engineers (the Corps) and Emergency Management Agency (FEMA) needed updated FEMA flood-insurance studies have been using a set of information on the flood magnitude and frequency for the flood magnitude and frequency values that were initially eight active streamflow-gaging stations along the main stem computed in 1962 (U.S. Army Corps of Engineers, 1962) and Delaware River in New Jersey, New York, and Pennsylvania were last updated in 1984 (U.S. Army Corps of Engineers, that included the three recent floods in order to update its 1984). The effects of reservoir storage were removed from flood insurance studies. Therefore, the U.S. Geological Survey the observed flood peaks using a HEC-1 computer program (USGS) computed updated flood magnitude and frequency (U.S. Army, Corps of Engineers, Hydrologic Engineering values following the guidelines published by the Interagency Center, 1973) with the assumption that the reservoirs were Advisory Committee on Water Data in its Bulletin 17B.

  • Assessment of Public Comment on Draft Trout Stream Management Plan
    Assessment of public comments on draft New York State Trout Stream Management Plan OCTOBER 27, 2020 Andrew M. Cuomo, Governor | Basil Seggos, Commissioner A draft of the Fisheries Management Plan for Inland Trout Streams in New York State (Plan) was released for public review on May 26, 2020 with the comment period extending through June 25, 2020. Public comment was solicited through a variety of avenues including: • a posting of the statewide public comment period in the Environmental Notice Bulletin (ENB), • a DEC news release distributed statewide, • an announcement distributed to all e-mail addresses provided by participants at the 2017 and 2019 public meetings on trout stream management described on page 11 of the Plan [353 recipients, 181 unique opens (58%)], and • an announcement distributed to all subscribers to the DEC Delivers Freshwater Fishing and Boating Group [138,122 recipients, 34,944 unique opens (26%)]. A total of 489 public comments were received through e-mail or letters (Appendix A, numbered 1-277 and 300-511). 471 of these comments conveyed specific concerns, recommendations or endorsements; the other 18 comments were general statements or pertained to issues outside the scope of the plan. General themes to recurring comments were identified (22 total themes), and responses to these are included below. These themes only embrace recommendations or comments of concern. Comments that represent favorable and supportive views are not included in this assessment. Duplicate comment source numbers associated with a numbered theme reflect comments on subtopics within the general theme. Theme #1 The statewide catch and release (artificial lures only) season proposed to run from October 16 through March 31 poses a risk to the sustainability of wild trout populations and the quality of the fisheries they support that is either wholly unacceptable or of great concern, particularly in some areas of the state; notably Delaware/Catskill waters.

  • Delaware River Watershed Business Plan
    National Fish and Wildlife Foundation Delaware River Watershed Business Plan March 2017 Purpose of a Business Plan The purpose of a NFWF business plan is to provide a concise blueprint of the strategies and resources required to achieve the desired conservation outcomes. The strategies discussed in this plan do not represent solely the foundation’s view of the actions necessary to achieve the identified conservation goals, but instead reflect the majority view of the many federal, state, academic, and organizational experts that consulted during plan development. This plan is not meant to duplicate ongoing efforts but rather to invest in areas where gaps might exist so as to support the efforts of the larger conservation community. Acknowledgements NFWF gratefully acknowledges the time, knowledge, and support provided by individuals and organizations that contributed significantly to this business plan through input, review, discussion, and content expertise relative to the Delaware Bay watershed, species, and habitat. In particular, thanks goes to members of the Advisory Team including: Jen Adkins, Partnership for the Delaware Estuary; Greg Breese , U.S. Fish and Wildlife Service; David Bushek, Rutgers University; Keith Curley, Trout Unlimited; Tim Dillingham, American Littoral Society; Matt Ehrhart, Stroud Water Research Center; Barry Evans, Penn State University; Sheila Eyler, U.S. Fish and Wildlife Service; Tom Fikslin, Delaware River Basin Commission; Cathy Haffner, Pennsylvania Game Commission; Pat Hamilton, New Jersey Department

  • Upper West Branch Delaware River
    Section 319 NONPOINT SOURCE PROGRAM SUCCESS STORY New York Restoration and Protection Activities in the Upper Branch of the Delaware River Protects New York City’s Drinking Water Supply The Upper West Branch of the Delaware River is a significant Waterbody Improved source of drinking water for New York City (NYC). It directly feeds the Cannonsville Reservoir, the third largest reservoir serving NYC. Historically, the Cannonsville Reservoir experienced summertime eutrophic (low oxygen) conditions because of high phospho- rus loads predominantly from nonpoint sources. New York State (NYS) placed the Upper West Branch of the Delaware River (UWBDR) on its 1998 303(d) list due to concerns about the vulner- ability of the reservoir to additional sources of phosphorus. Because efforts by the local commu- nity and numerous other partners successfully reduced phosphorus loads, the state removed the UWBDR from its 2004 impaired water list. Problem The UWBDR is in Delaware County in south- Prior to the restoration central New York. The UWBDR and its tributar- work in the watershed, the UWBDR’s tributaries ies encompass a watershed area of 450 square frequently suffered from miles with approximately 662 linear miles of riv- algae blooms caused by ers and streams that are the source waters for phosphorus inputs from the Cannonsville Reservoir.

  • Delaware River Basin States and New York City Announce One-Year Reservoir Operating Plan Agreement
    DELAWARE RIVER BASIN STATES AND NEW YORK CITY ANNOUNCE ONE-YEAR RESERVOIR OPERATING PLAN AGREEMENT MILFORD, Pa. (May 31) – New York State, Pennsylvania, New Jersey, Delaware, and the City of New York today announced that they have unanimously approved a one-year extension of the current Flexible Flow Management Program (FFMP) intended to meet water supply demands, protect fisheries habitat downstream of the New York City (NYC) Delaware Basin reservoirs, enhance flood mitigation, and repel the upstream movement of salt water in the Delaware Estuary. Releases of water from the three City reservoirs (Pepacton, Cannonsville, and Neversink) located in the headwaters of the Delaware River, and out-of-Basin diversions, are managed according to procedures unanimously agreed to by the four states and NYC under the terms of a 1954 U.S. Supreme Court Decree that settled an interstate water dispute between New York State and New York City, and the lower basin states. The Decree Parties (four basin states and NYC) will use the next year to further evaluate this interim reservoir management plan and use the experience to help guide ongoing negotiations to develop future multi-year agreements. The FFMP, which will be in effect through May 31, 2017, will continue to rely on use of the City’s Operations Support Tool (OST) to manage water forecasted to be available in the three NYC reservoirs and help guide selection of reservoir release rates. The OST is a sophisticated monitoring and modeling system that allows for better predictions of reservoir-specific water storage levels, quality, and inflows than previous tools.
