Watershed Boundary Dataset (WBD): 

Watershed Boundary Dataset (WBD) A Multi-Agency Effort to Create a Seamless, Hierarchical and Integrated Hydrologic Units for the Nation

Slide2: 

Vision for the geospatial framework for surface water Follow a drop of water from where it falls on the land, to the stream, and all the way to the ocean.

What is the Geospatial Framework for Surface Water? : 

What is the Geospatial Framework for Surface Water? A standard set of Watershed Boundaries (WBD) coupled with a National Stream Network (NHD) and the Topography that dictates the flow of Water across the Land Surface (NED andamp; EDNA)

Geospatial Framework for Surface Water: 

Geospatial Framework for Surface Water Sponsored by Federal Geographic Data Committee (FGDC) and Advisory Committee for Water Information (ACWI), Subcommittee for Spatial Water Data Information (SSWD)

Slide5:

Integration of Key National Datasets: 

Integration of Key National Datasets

Watershed Boundary Dataset (WBD): 

A single, seamless, hierarchical hydrologic unit dataset based hydrologic mapping principles. Consistent base scale of 1:24,000 GIS dataset with multi-functional attributes Served and maintained by a single entity Integrated with other key national datasets Common reporting unit for different levels of management needs Watershed Boundary Dataset (WBD)

Overview: 

. Water Accounting Uninterrupted Depiction of Flow Aggregation of Drainage Area Characteristics Overview

Slide9: 

Hydrologic Unit Codes

Hydrologic Unit Levels: 

Hydrologic Unit Levels

National WBD Coordination - SSWD: 

National WBD Coordination - SSWD Ensure communication between Federal, State, local Assess progress in each state Offer guidance on delineation method for states Ensure compliance with the National Guidelines Facilitate edge matching between states Provide supplemental datasets that expedite delineations Organize and attend workshops and training sessions

Watershed Boundary Dataset (WBD): 

Watershed Boundary Dataset (WBD) Data Availability Currently - 12 states or territories certified Goal - 32 states certified by end of December, 2004 2005 goal - 38 states certified Anticipated completion by summer, 2006 WBD website http://www.ncgc.nrcs.usda.gov/branch/gdb/products/watershed/index.html Website to download WBD – Geospatial Data Gateway http://datagateway.nrcs.usda.gov/GatewayHome.html

Slide13: 

Current Status of the WBD

Cooperating Agencies:: 

Cooperating Agencies: USDA Natural Resources Conservation Service U.S. Geological Survey U.S. Forest Service U.S. Environmental Protection Agency National Oceanic and Atmospheric Administration U.S. Bureau of Land Management U.S. Bureau of Reclamation U.S. Corps of Engineers Tribal Governments State Agencies Local Agencies

Challenges : 

Challenges Agency support is highly variable Delineation methods vary state to state Addressing cooperators needs to preserve existing watershed boundaries Inconsistent funding Edge-matching

Action Items for the Subcommittee members:: 

Action Items for the Subcommittee members: Increase awareness in your organizations Help make completion of the WBD a priority Assist the Subcommittee with a supported business plan Help identify potential funding sources

The Geospatial Framework For Surface Water Exists : 

But - It needs a substantial effort to reach its full potential, Many agencies (Federal andamp; State) andamp; private sector are working together to complete the tasks. The Geospatial Framework For Surface Water Exists

What will this Accomplish:: 

What will this Accomplish: An appropriate system for referencing of information about: Withdrawal Points Discharge Points Gage Locations Sampling Points Providing logical connections: upstream, downstream, and in the watershed

What does it take ? : 

Consensus definitions/standards (ACWI/FGDC) Develop tools Apply the tools to create the framework data Quality assurance Store andamp; disseminate the framework data sets Code features to the framework Train users Maintain the framework data sets What does it take ?

Slide20: 

We need a detailed, standardized and hydrologically sound national system of stream and watershed addresses. Without, it will be tough for the scientific and engineering communities to integrate and deliver water information.
