Chesapeake Bay Program Partnership
Non-profit organizationso Chesapeake Bay Foundationo Center for Watershed Protectiono Ducks Unlimitedo National Fish and Wildlife Foundationo And more
Academic institutionso Land grant universities o Cooperative Extension programso Sea Grant programso Research centers and consortiumso And more
The Partnership Approach
Brings together diverse leaders and experts across numerous political boundaries to collaborate on achieving a common goal –a healthy bayo Consolidate and coordinate effortso Share resourceso Compliment efforts and avoid duplication
Partners come together to evaluate data, share best practices, report on progress toward goals, and make policy and management decision
History of the Partnership
1983 Chesapeake Bay Agreemento Signed by governors of Maryland, Pennsylvania, Virginia;
mayor of District of Columbia; administrator of EPA; chair of Chesapeake Bay Commission
o Signatories became the Executive Council 1987 Chesapeake Bay Agreement
o 40% nitrogen reduction by 2000 Chesapeake 2000
o Goals to reduce pollution, restore habitat, protect living resources, promote sound land use practices, and engage the public
o Headwater states (Delaware, New York, West Virginia) joined the water quality restoration efforts
History of the Partnership
Executive Order 13508 (May 2009)o Increased focus and emphasis on Bay restoration
Total Maximum Daily Load (December 2010)o Set limits on nitrogen, phosphorus, and sedimento 100% of the actions to achieve the TMDL must be in place by
2025o 60% of the actions to be in place by 2017
Watershed Implementation Plans (2010, 2012, 2017)o Outlines how jurisdictions will achieve load reduction goalso Spatial and temporal goals for implementing best
management practices (BMPs) 2-Year Milestone Goals
o Interim goals that ensure accountability and progress toward 2017 and 2025 targets

Why use models? Mathematical representations of complex
systemso Models synthesize large amounts of data
• The Chesapeake Bay our nations largest estuary!• Large watershed with
diverse topography and land use
• Critical habitat for many plants and animals
Model scenarios predict responses to changes in inputs and processes
Why use models? Models are part of a toolkit for decision
making

Establish Total Maximum Daily Load reductions
Track load changes over time
Partnership ModelsA series of

Phase 1 Phase 5
Completed in 2010 1,000+ model segments
30 land uses 21 year calibration period
1400 BMP designations
Phase 4
Completed in 1998 94 model segments 9 land uses 14 year calibration period

Model Improvements Continue
Improvements in precision, scope, complexity, and accuracy have occurred over time
The Partnership is committed to continuously improving the models
Revisions regularly shared for review, testing, and recommendations by Partnership
New creditable data and restoration practices can be incorporated
Extensive independent scientific peer review

The Chesapeake Bay Program…
is a partnership between federal, state, and local government agencies, non-profit groups, and academic institutions with a common goal of restoring the health of the Bay.
is organized to allow thorough participation, review, and feedback on a variety of issues to help make management decisions and achieve restoration goals.
The Chesapeake Bay Models…
are linked to project loads of nitrogen, phosphorus, and sediment and simulate how management decisions regarding pollution controls, land use, and atmospheric deposition could impact the ecosystem, specifically focusing on water quality and living resources.
have been and will continue to be modified over time as new and better sources of data become available and as new technologies to reduce pollutant losses are developed and adopted.
