Chesapeake 2000 and the Bay

CBP 1/5/06

CHESAPEAKE BAY PROGRAM

The Chesapeake Bay is North America’s largest and most biologically diverse estuary, home to more than

3,600 species of plants, fish and animals.

CBP 1/5/06


For more than 300 years, the Bay and its tributaries have sustained the region’s economy and

defined its traditions and culture.

CBP 1/5/06


It is a resource of extraordinary productivity, worthy of the highest levels of

protection and restoration.

Migratory and Resident Fish Habitat ExpandingThe removal of dams and the construction of fish passages are reopening native spawning grounds to migratory and resident fish in many parts of the watershed. When combined with stocking efforts, migratory species are beginning to return.

The removal of dams and fishway construction from 1988 through 2005 reopened 1,838 miles of historic habitat to migratory and resident fish.

The new agreement commits to set a new goal for additional fish passages and to revise fishery management plans to include habitat and target population sizes for migratory fish.

Shad Are Starting to Make a Comeback

but Have a Long, Long Way to Go

Stocking efforts, a moratorium, and fish passage development increased the number of shad counted at Conowingo Dam from several hundred per year in the early 1980s to an average of 101,140 per year in 2003-2005.

Rockfish Population Stable

Rockfish have rebounded to levels not seen since the 1950’s, but concerns remain over disease, sufficient sources of food and availability of spawning habitat.

Although we have sustainable populations of striped bass, we do not have sustainable populations of many other species. The new agreement commits to develop ecosystem-based multi-species management plans for targeted species by 2005.

Wetlands are a valuable piece of the Bay’s ecosystem. They filter and capture pollutants, provide wildlife habitat, protect shorelines and reduce flooding.Wetlands are being restored throughout the watershed, but remain at risk to development pressures. We have achieved 40% of the wetland acreage gain goal through non-regulatory programs.

The new agreement commits to restore 25,000 acres of tidal and non-tidal wetlands by 2010.

CBP 1/5/06


Watershed Management Plans

Source: Chesapeake Bay Program. *Represents the cumulative total as of December, 2004. 2004 acreages are estimated using the best information available. It is expected that tracking of watershed management planning will be improved and 2004 data may be adjusted, both for overestimates and underestimates of acreage covered by plans.

The new agreement commits to implement locally supported watershed management plans in 2/3 of the Bay watershed by 2010.The plans need to:• “Address the protection, conservation and restoration of stream corridors, riparian forest buffers and wetlands”• Reflect the goals and objectives of “improving habitat and water quality” • Identify implementation mechanisms• Have demonstrated local support.

As of December 2004, watershed management plans have been developed and are being implemented on 9.7 million acres in the watershed portions of MD, PA, VA and DC. In order to achieve the goal, plans need to be developed for 13 million additional acres by 2010.

CBP 1/5/06


The new agreement also commits to:

• Achieve a no-net loss of existing wetlands acreage and function.

• Implement wetlands preservation plans in 25% of the watershed by 2010.

Bay and River Water Quality Commitment

Achieve and maintain the 40% nutrient reduction goal agreed to in 1987 and… By 2010, correct the nutrient‑ and sediment‑related problems in the Chesapeake Bay and its tidal tributaries sufficiently to remove the Bay and the tidal portions of its tributaries from the list of impaired waters under the Clean Water Act.

Section 1: What Do We Want to Achieve

In order to achieve and maintain the water quality necessary to support aquatic living resources, the partners committed to:

CBP 1/5/06


Impaired Waters and Clean-up Plans


Portions of the Chesapeake Bay and its tidal rivers are listed under the Clean Water Act as “impaired waters” largely because of low dissolved oxygen levels and other problems related to nutrient pollution.

This “listing” requires the development of a clean-up plan for the Bay by 2011.

Progress toward Meeting Nutrient and Sediment Goals LimitedThe Chesapeake Bay Program Watershed Model provides program managers with a way to estimate the nutrient and sediment reductions that will likely occur as pollution abatement practices are implemented throughout the watershed. These reduction estimates also provide an indication of the pollutant load that would flow into the Bay in an "average” year. Using the model, managers can project the future response of various management actions put in place today.

Based on Bay watershed model simulations, 58% of the phosphorus, 41% of the nitrogen and 54% of the sediment reduction goals have been achieved.

Source: CBP Phase 4.3 Watershed Model. Estimates of nutrient and land-based sediment reductions that may occur when the reported management practices and reduction technologies are implemented within watershed portions of NY, PA, MD, DC, DE, WV, VA. The model's nonpoint source load reductions are estimates of what would occur under long-term avergaed rainfall conditions based on the years 1985-1994. The point source load reductions are actual measurements and are influenced by the reporting year’s rainfall.

Chesapeake 2000 Goal: Sound Land Use

“Develop, promote and achieve sound land use practices which protect and restore watershed resources and water quality, maintain reduced pollutant loadings for the Bay and its tributaries, and restore and preserve aquatic living resources.”

CBP 1/5/06


Since 1950, the Bay watershed’s population has doubled to about 16 million people. As the population of the watershed grows, so does our footprint on the landscape.In the past decade, population increased by about 8 percent, while the amount of impervious surface increased by 41 percent, representing an area five times the size of the nation’s capital.Managing future growth will be critical to preserving gains made during the first two decades of Bay restoration efforts.
