Initiative
Despite billions of dollars spent in the last
three decades to address impairments to
water resources, aquatic ecosystems are
still in decline. A recent EPA survey of the
nation's wadeable streams found 42 percent in poor
biological condition and 25 percent in fair condition.
Nearly 40 percent of North America's freshwater
fish, 700 species in total, are imperiled. We face a
serious conservation crisis.
The solution demands a more integrated approach
that looks broadly to maintain water quality and
ecological integrity on a geographic - or watershed
basis. Thanks to today's highly advanced assess-
ment, planning and data anaylsis tools, we now can
achieve the vision for holistic water resource man-
agement embraced by EPA and others in the early
1990's. Under the new Healthy Watersheds Initia-
tive, EPA is proposing:
A Strategic Framework that outlines a systems-
based approach to integrated watershed assess-
ment, protection and conservation programs.
A New Policy Direction that focuses on main-
taining healthy waters and meeting Clean Water
Act (CWA) goals of fishable and swimmable.
A Collaborative Approach that integrates CWA
programs and other aquatic resource programs
across agencies and the private sector.
Technical Assistance and Funding to states
and watershed organizations to support healthy
watershed assessment and conservation.

Why Emphasize Healthy Watersheds?
H
ealthy watersheds provide numerous environmental benefits and services, including clean water for healthy
aquatic ecosystems, habitat for fish and wildlife, drinking water, recreational opportunities, and reduced vulner-
ability to severe impacts from invasive species, climate change and future land use changes.
Habitat for Fish and Wildlife
Healthy watersheds and streamside areas provide clean water
and habitat for fish, amphibians, birds and insects, and offer
green corridors that connect animal and bird populations to
food and water sources. Maintaining healthy watersheds also
makes economic sense. Healthy watersheds serve as refuges
where people spend money to fish, boat, hike and pursue other
recreation opportunities.
Better Resilience Against Storms and Floods
Healthy watersheds tend to suffer less damage from floods,
fires, and other natural disasters, thereby reducing costs to
communities.
Lower Drinking Water Treatment Costs
Protecting aquifer recharge zones and surface water sources
reduces drinking water treatment costs. For every 10 percent
increase in forest cover, the chemical and treatment costs
decrease by 20 percent according to a survey of 27 different
water treatment utilities (Ernst, et al., 2004).
Our Most Treasured Waters Are At Risk
Over the last 50 years, coastal and freshwater wet-
lands have declined; surface water and groundwater
withdrawals have increased by 46%; and non-native
fish have established themselves in many water-
sheds (Heinz Center, 2008).
A recent national water quality survey of wadeable
streams showed that 42% of the nation's stream
length is in poor biological condition and 25% is in
fair biological condition (U.S. EPA, 2006).
Nearly 40% of fish in North American freshwater
streams, rivers, and lakes are found to be vulnerable,
threatened, or endangered; nearly twice as many
as were included on the imperiled list from a similar
survey conducted in 1989 (Jelks et al., 2008).
The cost of protecting watersheds is
much less than the cost of restor-
ing impaired waters. Choosing to
protect ecologically valuable systems will
save money in the long run."

Expanding the Watershed Approach
The Healthy Watersheds Initiative focuses on using a holistic approach to protect and
conserve healthy aquatic ecosystems. To maintain ecological integrity of aquatic
resources, watershed managers need to understand not only the biological, chemi-
cal and physical condition of waterbodies, but also critical watershed functional attributes,
such as hydrology, geomorphology and natural disturbance patterns. Programs that protect
and restore aquatic ecosystems are most effective when they integrate these dynamics and
manage watersheds as systems. To maintain healthy aquatic ecosystems, the processes
that drive their condition need to remain intact. In addition to the traditional focus on chemi-
cal and physical parameters, the goal is to look more broadly at overall health and condition
taking into account key dynamics of the watershed system.
The Healthy Watersheds Framework is largely consistent with the ecological attribute approach found in the Frame-
work for Assessing and Reporting on Ecological Condition, a tool developed by EPA's Science Advisory Board in 2002
(see www.epa.gov/nps/healthywatersheds/publications.htmWintegrated). The framework provides a construct for ad-
dressing the dynamic complexities of watershed ecosystems through an integrated assessment of essential ecological
attributes.

Healthy Watersheds Framework's Essential Ecological Attributes
The Healthy Watersheds concept views watersheds as integrated systems that can be un-
derstood through the dynamics of essential ecological attributes, including:
Landscape Condition. Natural vegetative habitat patches and cor-
ridors provide the green infrastructure, or interconnected natural art
necessary to maintain good landscape condition in healthy watersh-
Biotic Condition. Healthy aquatic ecosystems reflect healthy watei
shed conditions. The biotic condition is measured by examining both
habitat and the presence, numbers and condition of aquatic organisr"
and communities in a waterbody.
Chemical/Physical Parameters. Parameters such as nutrients,
temperature, dissolved oxygen, organic matter and pH are importar
components of ecosystem health.
Natural Disturbance Regimes. Understanding the natural disturbance
etc.) of a watershed allows managers to develop management and prote
the watershed in as natural a condition as possible.
Hydrology/Geomorphology. Healthy streams have a natural flow regime with a magnitude, frequency,
duration, timing and rate of change that creates habitat for multiple species. Further, in a healthy stream,
erosion and sediment deposition rates achieve a balance, or dynamic equilibrium, based on water flow,
soil type and other factors. The dynamic equilibrium of the physical system establishes the dynamic equi-
librium of the biological system, thus maintaining the ecological integrity of the system as a whole.
Identifying and Protecting Healthy Watersheds
Many states, local governments, and non-governmental organi-
zations are leaders in protecting high quality waters and healthy
watersheds. For example, Virginia used an integrated assessment
approach in developing its watershed integrity model. Virginia's
natural landscape assessment information combined with water
quality data (modified IBI), source water protection zones, head-
water streams and contributing areas, an index of terresterial
integrity, and other assessment information provides the basis for
identifying high quality watersheds.

After identifying healthy watersheds or healthy components of
watersheds, watershed managers or local planning authori-
ties can incorporate a variety of strategies to ensure that the
watersheds remain healthy. EPA's new Healthy Watersheds Web site
describes a series of conservation and protection approaches and
provides links to case studies, reports and useful tools. Often a mix
of tools need to be tailored for a particular location to most effectively
maintain watershed health and integrity. The Web site provides tools
for:
Habitat and biodiversity conservation
Green infrastructure and landscape conservation
River corridor protection
Land protection programs and local land use ordinances
The New Healthy Watersheds Web site
provides the tools and information that
states, local governments and others need
to identify and protect healthy watersheds.
The Rivanna River Basin and Healthy Watersheds
The Rivanna River Basin contains some of the highest quality river and stream sys-
tems located in piedmont Virginia. In addition to having numerous endemic and rare
species, the rivers provide recreational opportunities and drinking water for the grow-
ing population of Charlottesville and the surrounding area. The Rivanna River Basin
Commission, chartered under state law and comprised of local communities, was es-
tablished to help local jurisdictions make decisions that are consistent with protecting
the river's health. Several activities in the Basin support this goal and include elements
of a healthy watersheds approach.
The Rivanna Healthy Waters Implementation Project will bolster the conservation of|
healthy streams by identifying these streams through a biological assessment and
developing tools to support local protection of the ecological integrity of these streams.
The Rivanna Water and Sewer Authority developed a 50-year Community Water Supply Plan to improve river flows by
mimicking natural flows from its reservoirs and to provide for stream buffers in permanent conservation easements.
The City of Charlottesville integrated an urban Green Infrastructure Strategy into the city's Comprehensive Plan,
including urban forest conservation, walking trails, water quality and riparian habitat protection.
Fluvanna County's Comprehensive Plan emphasizes the importance of green infrastructure through a conservation
easement program and cluster development regulations, along with renewing its Agricultural/Forestal District.
The Thomas Jefferson Planning District Commission (TJPDC) is developing a Green Infrastructure Plan that includes
the entire Rivanna watershed. The Plan identifies habitat corridors using the Virginia Conservation Lands Needs
Assessment, Tier III and identified "healthy waters," lands protected by easement, and other critical layers of green in-
frastructure. The River Basin Commission is working with TJPDC to incorporate protective measures into local plans
and codes.
Collaboration and Partnerships are
Key to Success
To realize its vision for healthy watersheds, EPA recognizes
the need to work collaboratively with other federal agen-
cies, state, tribal and local organizations as well as with local
watershed groups and private organizations such as recreational
fishing groups that care deeply about clean water. Over the next
several years, EPA will be build on existing partnerships and le-
verage national and regional conservation efforts, including many
already underway, (e.g., the National Fish Habitat Action Plan).
