Connectivity of Streams and Wetlands to Downstream Waters: A
Review and Synthesis of the Scientific Evidence


AGENCY: Environmental Protection Agency.

ACTION: Notice of availability.

-----------------------------------------------------------------------

SUMMARY: The U.S. Environmental Protection Agency (EPA) is announcing
the availability of the final report titled, ``Connectivity of Streams
and Wetlands to Downstream Waters: A Review and Synthesis of the
Scientific Evidence
'' (EPA/600/R-14/475F). The purpose of this report
is to summarize the current understanding about the connectivity and
mechanisms by which streams and wetlands affect the physical, chemical,
and biological integrity of downstream waters.
    The report is available via the Internet on the EPA Office of
Research and Development (ORD), National Center for Environmental
Assessment's Web site (www.epa.gov/ncea) under the Recent Additions and
Publications menu.

DATES: The Agency is releasing the report publicly on January 15, 2015.

ADDRESSES: The report is available primarily via the Internet on the
EPA Office of Research and Development (ORD), National Center for
Environmental Assessment's Web site (www.epa.gov/ncea) under the Recent
Additions and Publications menu. A limited number of paper copies will
be available from the Information Management Team, National Center for
Environmental Assessment; telephone 703-347-8561; facsimile: 703-347-
8691. If you are requesting a paper copy, please provide your name,
your mailing address, and the document title.

FOR FURTHER INFORMATION CONTACT: For additional information concerning
the assessment, contact EPA National Center for Environmental
Assessment, Dr. Laurie Alexander, telephone 703-347-8630 or email
Alexander.Laurie@epa.gov.

SUPPLEMENTARY INFORMATION:

Information About the Project/Document

    The U.S. Environmental Protection Agency (EPA) Office of Research
and Development (ORD) developed this report to review and synthesize
the peer-reviewed scientific literature on the connectivity or
isolation of streams and wetlands relative to large water bodies such
as rivers, lakes, estuaries, and oceans. The purpose of the report,
``Connectivity of Streams and Wetlands to Downstream Waters: A Review
and Synthesis of the Scientific Evidence,'' is to summarize the current
understanding about the connectivity and mechanisms by which streams
and wetlands, singly or in aggregate, affect the physical, chemical,
and biological integrity of downstream waters. The report addresses
three main questions related to connectivity:
    (1) What are the physical, chemical, and biological connections to,
and effects of, ephemeral, intermittent, and perennial stream on
downstream waters?
    (2) What are the physical, chemical, and biological connections to,
and effects of, riparian or floodplain wetlands and open-waters on
downstream waters?
    (3) What are the physical, chemical, and biological connections to,
and effects of, wetlands and open-waters in non-floodplain settings on
downstream waters?
    This report informs development of a rule proposed by EPA and the
U.S. Army Corps of Engineers to clarify the definition of waters of the
United States under the Clean Water Act (http://www2.epa.gov/uswaters).

    Dated: December 30, 2014.

Acting Deputy Director, National Center for Environmental Assessment.
