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! Stay in touch on our NHD website at:
