Fairchild Building, Room 709 (EPA)
499 South Capitol Street, S.W.
WELCOME, INTRODUCTIONS AND OPENING REMARKS: Eighteen
representatives of four agencies attended the meeting to discuss Federal
activities involving spatial water data. The agenda is attached at the
end of this text. The U.S. Geological Survey (USGS) /Water Information
Coordination Program (WICP) sponsored the meeting in consultation with
representatives of the Federal Geographic Data Committee (FGDC). Nancy
Lopez, Chief of the Office of Water Information Coordination, chaired
the meeting. A list of attendees is below:
PURPOSE OF THE MEETING: The group met for the following purposes:(1) To exchange information about spatial data requirements for watershed assessment and restoration, (2) to identify water-related spatial data issues that need to be coordinated among the agencies and with other organizations, and (3) to discuss selected spatial data activities of the Federal Government including the National Elevation Dataset, watershed and subwatershed boundary datasets, and the USGS Cooperative Research and Development Agreement (CRADA) with Microsoft. At the request of the presenter because of a conflict and because of time constraints, the fourth presentation on the agenda (Open Access and EnviroMapper) was rescheduled to the next meeting.

NEW ACTION ITEMS:
The group will address the following topics at the May
meeting: Multi-Resolution Land Characterization, Digital Soils
Datasets, and Open Access. The group will also begin talking about
interagency collaboration to achieve common objectives.
At the June meeting the group will discuss watershed modeling
including the EPA Basins Model, the USGS Sparrow Model, and the work
underway at the NRCS to address watershed issues.
At a future meeting, the group will invite the NWS to discuss
hourly precipitation products that integrate NEXRAD and in situ
monitoring within watersheds.
The NRCS and FWS will be invited to a future meeting to
discuss information about new White House policies related to wetland
mapping and plans to track/map gains and losses in wetlands on an
STATUS OF OLD ACTION ITEMS:
USGS/WICP-Hold a meeting in less than a month on spatial data
for watershed assessment. Include a briefing on digital elevation
data at that meeting. DONE
USGS/WICP-Distribute the guidelines for delineating and
digitizing higher resolution watershed boundaries for review and
approval by Federal agencies within 30 days. PENDING
USGS/WICP-Once the Watershed Boundary Dataset guidelines are
distributed, hold a briefing seminar for Federal agencies. The
purpose of the meeting would be to review the guidelines and explain
the rationale for the approaches recommended in the guidelines.
All Attendees-Before the next meeting review and comment on
the preliminary discussion draft for Terms of Reference (Terms) for
the Subcommittee on Spatial Water Data.
USGS/WICP and FGDC-Once agencies have an opportunity to
comment, then the revised Terms will be distributed to the Advisory
Committee on Water Information and the Federal Geographic Data
Committee for review and approval. PENDING
All Attendees-Identify additional people and organizations
that need to participate in future meetings. For example, a
representative from the Federal Emergency Management Agency should be
invited to attend the next meeting to discuss Digital Flood Insurance
Rate Maps. As soon as possible, the Subcommittee needs to convene and
begin operating as a national forum with meetings open to the public.
FEMA HAS BEEN CONTACTED. NATIONAL FORUM PENDING.
SPATIAL DATA NEEDS FOR WATERSHED ASSESSMENT AND RESTORATION. Agencies
attending the meeting discussed their activities and requirements
related to spatial data for watershed applications. To begin the
discussion, Nancy Lopez distributed an appendix from a draft publication
prepared by the Forest Service and the Bureau of Land Management. Keith
McLaughin provided the draft information for distribution to the group,
but was unable to attend the meeting. The appendix is entitled "Core
Hydro-Meteorological Data and Information Protocols, " and it is part of
a draft report that FS is currently printing entitled Interagency
Protocols for Hydrologic Condition Assessment. The report is intended
to be interim guidance for field offices; it will be open for comment
for a year or more before the guidance is considered final.
ENVIRONMENTAL PROTECTION AGENCY. Andy Battin indicated that
original work on Multi-Resolution Landscape Characterization (MRLC) is
not complete and needs to be wrapped up. Future efforts related to MRLC
need to focus on ways to accelerate the availability and distribution of
updated land cover information. Also, Andy noted that the EPA Basins
Model will require hourly precipitation data spatially distributed over
the watershed. He indicated that EPA does not have a national file of
water bodies/reaches with the uses that are designated by States.
Tod Dabolt/Monitoring Branch stated that EPA needs the National
Hydrography Dataset (NHD) to be completed at the 1:100,000 scale ASAP
to support the President's Clean Water Action Plan, Clean Water Act
Section 303(d), Total Maximum Daily Loads (TMDL), work related to
litigation and myriads of other applications that need reach locations
and identifiers. Also, Tod discussed the need for higher resolution
information about the locations of riparian-wetland areas.
Betsy Henry/Ground Water Protection discussed their work to obtain
latitude and longitude (lat/long) data for water supply intakes
nationwide. These data have not been required in the past, and data
about the locations of water supply systems that are currently available
at the State level generally lack quality control. The EPA is working
with the Ground Water Protection Council, a national level association
of State ground water managers, to improve these data. Also, EPA has
contracted with the USGS/WRD to assist in efforts to improve the
location data in the Safe Drinking Water Information System.
Wendy Blake-Coleman/Office of Water discussed the general need to
provide lat/long as a location identifier for water -related map
features. In addition, she indicated that water quality assessment
efforts also need information about atmospheric deposition. Thus, there
is a need to define and map "airsheds" that contribute pollutants to
impaired waterbodies and and their watersheds. Wendy also discussed a
system called EnviroFax that is a data warehouse used by EPA. Other
agencies can access the system.
