North Fork of the Payette
• “Completed” at 1:24,000 scale
• Information mostly derived from USGS topographic maps and USGS cartographic feature files
• Even though NHD available at 1:100,000 and 1:24,000 scale, our efforts are focused on improving 1:24,000K
We want to...
• Add more names to the NHD. Currently only 31% of flowlines have names.
• Improve connectivity and stream classification (perennial, intermittent, ephemeral).
• Add and improve other features such as springs, and dams as well as improve attribution of streams
NHD on top of NAIP 2004
We are..
• Improving geometry
• Improving flow directions and connectivity
• Gathering information from Irrigation Districts and other Land Managers
Customized NHD Edit Tool
Photo-revised and “hand-edited” paper maps
Lake Pend Oreille
We want to..
• Eventually include attributes into the 24K NHD data that allows for flow modeling and Streamstats
• Encourage the application of the NHD – for example
• Address water rights to the NHD
• SPARROW water quality monitoring
• Fish Passage Support System
We want to..
• Hear from you! Please submit updates, data and suggestions.
• Tell us how you are using the NHD!
