**Notes:**
Focus of the Subcommittee for the last 2 years is getting these datasets developed and available.  Important that these data sets work together.

## Interagency Development  of a Reference Set of Watersheds for the United StatesWBD

**Interagency Development  of a Reference Set of Watersheds for the United States****WBD**

## Hydrologic Unit Codes

## WBD

- .

**WBD**

**Notes:**
Example of the Hierarchical Structure
Water Accounting: Assignment of a detailed, unambiguous address to any point and/or area small enough to be relevant to local, state and national program water resource initiatives.

Depict the flow of water through the landscape: The network connectivity of each nested level is identified within the structure of the WBD. Allowing easy identification of upstream and downstream units ant multiple scales.

The aggregation of Basin characteristics: Both horizontal and vertical integration with other component datasets. The WBD is designed and created to be interoperable with both national and local datasets.

## WBD STATUS

**WBD**** STATUS**
**as of September ‘04**

## Challenges 

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

**Notes:**
Examples:

Pacific Northwest:	Contractual misunderstandings

Louisiana:			No support

Minnesota:			No support, 

North Dakota		Funding Issues and methodology.

## Technical 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**

## Recent WBD Activities

**Recent WBD Activities**

## Request the Subcommittee members:

** ****Increase awareness in your organizations**
** ****Help make completion of the WBD a priority**
** ****Help identify potential funding sources**
** ****Assist the Subcommittee with a supported****    business plan ****(how to get WBD completed)**

**Notes:**
Increase awareness and support in each of your organizations by make the completion of the WBD a priority.

Assist National Coordination team with a supported business plan.

Help National Coordination Identify potential funding sources.

Assure that the National Coordination Team contains oversight and leverage with regard to funding allocation.

**Metadata search**
**17 “channels” of data, following ISO categories**
**Channels can feature the key datasets**
**Inland Water Resources**
**The Drainage Network**
**Major Water Databases**

## Inland Water Resources

**Current features:**
**National Hydrography Dataset**
**HUC Image Service**
**National Wetlands Inventory**

## The Drainage Network

**Current features:**
**National Hydrography Dataset**
**National Elevation Dataset – Shaded Relief**

## Major Water Databases

**Current features:**
**Enviromapper**
**NWIS**
**STORET**

## Role of the Spatial Water Data Subcommittee

**“****Board of Directors” for the GOS Inland Water Channel**
**General guidance on content selection**
**Help resolve conflicts**
**Recommend datasets for featuring**

## Resolution

**ACWI encourages the Spatial Water Data Subcommittee to provide guidance and direction to the Geospatial One-Stop Inland Water Channel.**
