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

## Subcommittee’s role

**2-digit= 1st level = 22 regions  **

**4-digit= 2nd level = 222 subregions  **

**6-digit= 3rd level = 789 accounting  **

**8-digit= 4th level = 2223 cataloging**

**10-digit= 5th level = ~22,000 watersheds**

**12-digit= 6th level = ~160,000 subwatersheds**

## Problematic States

**Arizona:****   ****NRCS,USFS and BLM do not recognize need for 6****th**** Level Delineations****.**
**Idaho:**** ****        Lack of in-kind funding.**
**North Dakota:****     ****Inefficient process, minimal funding.****  **
**Minnesota:**** ****    Too much detail is being added well beyond the needs of the WBD. Estimated completion date at the current rate is 15 years. Plenty of funding, but have not been amenable to changing process.**
**Louisiana:****    ****No local support.**
**New York:****    ****Inefficient process, lack of coordination.**
**New Jersey:****   ****Reluctant to modify existing dataset  **** **

**Hydro Standard **
**Work Group**

**Notes:**
New workgroup formed to develop a “National Hydro Data Content Standard”

## National Hydrography Framework Standard 

**Develop formal ****Content Standard**** for Hydrography. **
**describe a ****general model**** (a data dictionary, definitions, relationships) **
**application-independent, **
**supports**** ****international standards**
**facilitates the exchange of data. **

**Notes:**
Purpose of this hydro standard.  Build on NHD and Consortium work.  FGDC paying for a facilitator to get this through

## Geospatial One-Stop

**Key points**
**Develop and implement Framework Data content standards **
- Elevation
- Orthoimagery
- Hydrography
- Administrative Boundaries
- Transportation Networks
- Cadastral
- Geodetic Control
**Establish comprehensive Federal Portal **
