Subsequent to October 1963, entire flow from 454 mi² of drainage area controlled by Cannonsville Reservoir (station 01424997). Part of flow diverted for New York City municipal supply. Remainder of flow (except for conservation releases and spill) impounded for release during period of low flow in the lower Delaware River basin, as directed by. It looks like the release from Cannonsville Reservoir was increased to around 725 cfs. This was probably done to help mitigate any potential spill since the reservoir levels are still climbing.

The 917-km2 Cannonsville Reservoir Basin (CRB) is the source of water for the Cannonsville Reservoir. The CRB is a portion of the Northern Delaware River 8-digit HUC (02040101). There is a history of data collection at multiple scales and some limited research within the CRB, but more intensive data collection and research ha For Cannonsville and Pepacton, MARFC ran five hypothetical model simulations for the cases of no reservoir, three different reservoir voids, and no spill, to show the effects of these hypothetical scenarios on river levels at ten downstream NWS forecast points. Summaries of the simulation results are shown in the tables in this report. The number

Paddlers and canoe enthusiasts rejoiced last year when the New York City Department of Environmental Projection announced that it would be opening up the Cannonsville reservoir in Delaware County to recreational boating. But right now, the Cannonsville's waters are so low that boating is nearly impossible.
required a massive pre-storm drawdown of pool levels of 41.93 ft (53.9 billion gallons) at Cannonsville reservoir and 19.95 ft (34.5 billion gallons) at Pepacton reservoir. Such an unrealistic drawdown would hypothetically yield a crest reduction of 2.0 to 10.3 ft on the Upper Delaware, and 1.6 to 3.1 ft on the Lower Delaware Drinking water for New York City is supplied from several large reservoirs, including a system of reservoirs west of the Hudson River. To provide updated reservoir capacity tables and bathymetry maps of the City's six West of Hudson reservoirs, bathymetric surveys were conducted by the U.S. Geological Survey from 2013 to 2015. Depths were surveyed with a single-beam echo sounder and real.

The Cannonsville Reservoir is the third largest reservoir in NY City's water supply system; it was constructed by damming the West Branch of the Delaware River in the early 1960s and became part of the reservoir system owned by the City of NY in 1966. Land for the reservoir was condemned and purchased from townspeople and farmers Cannonsville Dam is the westernmost dam in NYC's water supply, and it captures water from the Delaware River, which flows through Trenton, NJ and Philadelphia, PA. Placed into service in 1964, Cannonsville Reservoir was the last of New York City's 19 reservoirs to be built

SYSTEM DESCRIPTION Cannonsville Reservoir (latitude 42˚02´46´´, longi-tude 75˚22´24´´, at dam) is located in upstate New York, approximately 190 km from New York City (NYC) (Figure 1). This impoundment is NYC's newes draining into Cannonsville Reservoir at Beerston is located in Delaware County, New York, in the Catskill Mountains (Figure 1). The WBDR upstream of Beer-ston is 80 km long and flows to the southwest, drain-ing an area of 912 km. 2. Elevations in the watershed range from 353 m to 1,019 m above mean sea level

NYS listed this segment on its 1998 303(d) list of impaired waters for not meeting criteria to support its designated use—aquatic life support—due to excess phosphorus levels Spilling reservoirs upriver could complicate crest levels in the Delaware during the heavy rains forecasted for this weekend.

Cannonsville Dam • Completion date: 1964 • Reservoir is contained by a earthen dam with impervious clay core and a split-level spillway • Classified as a Class C High-Hazard Dam per NYSDEC regulations • The Cannonsville Reservoir has a 455 sq mi drainage area and a 7.5 sq mi surface area holding 97 billion gallons of water. under generally accepted assessment methodology employed by DEP. The Cannonsville reservoir is the only eutrophic water body in the Catskill/Delaware portion of the Watershed, while 9 of the 10 reservoirs within the Croton portion of the Watershed have been classified as eutrophic based on data collected by DEP since 1988. DEP Report at 1, 3 The problem is particularly severe in the Cannonsville Reservoir, which is routinely taken offline during the summer and fall because of high algae levels (NYC DEP, 1993b). Current phosphorus levels and the associated formation of DBPs meet regulatory requirements in the other Catskill/Delaware reservoirs

The relationship cited above points out that current phos- phorus loadings to Cannonsville Reservoir are much too high and that a reduction of the loadings to natural or background levels (without point source influence) should markedly decrease the eutrophication rate of Cannonsville Reservoir The Cannonsville Reservoir in the Catskill Mountains is one of several fresh water repositories of drinking water for the Big Apple. Route 17 is the main escape route of New Yorkers to the. The downstream impacts of the high volume water releases from Cannonsville reservoir that may occur until the projected completion of the repair work (September 2015). The potential for severely low water levels in the reservoir and how that will impact water releases through the fall and winter The West Branch is fed by Cannonsville Reservoir, which is the water source for New York City. Water releases throughout the summer keep the river hospitable for the trout. In fact, the West Branch tends to get more of these water releases through the summer than the East Branch, making it the better location for warm-weather fishing It would have required lowering the Cannonsville reservoir to a level of 44 percent of capacity and the Pepacton to 75 percent — about 88 billion gallons of water total
