Problematic States
Arizona: NRCS,USFS and BLM do not recognize need for 6th 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

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.
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 – Director Hank Garie, USGS
