WBDHU10 Partner Fish Passage Survey Priorities

Hydrologic Units are delineated to nest in a multi-level, hierarchical drainage system with corresponding HUCs, so that as you move from small scale to large scale the HUC digits increase in increments of two. For example, the very largest HUCs have 2 digits, and thus are referred to as HUC 2s, and the very smallest HUCs have 12 digits, and thus are referred to as HUC 12s.</span></p><div style="font-family:&quot;Avenir Next W01&quot;, &quot;Avenir Next W00&quot;, &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, sans-serif;font-size:16px;"></div><div style="font-family:&quot;Avenir Next W01&quot;, &quot;Avenir Next W00&quot;, &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, sans-serif;font-size:16px;"><div style="color:rgb(77, 77, 77);font-family:&quot;Lucida Grande&quot;, &quot;Lucida Sans Unicode&quot;, Arial, Helvetica, sans-serif;font-size:14px;margin:0px;padding:0px;"><img style="height:auto;max-width:100%;" src="https://downloads.esri.com/blogs/hydro/AGOL_Content/WBD.jpg" alt="WBD HUCs"></div></div><div style="color:rgb(77, 77, 77);font-family:&quot;Lucida Grande&quot;, &quot;Lucida Sans Unicode&quot;, Arial, Helvetica, sans-serif;font-size:14px;margin:0px;padding:0px;"></div><p><span style="font-family:&quot;Avenir Next W01&quot;, &quot;Avenir Next W00&quot;, &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, sans-serif;font-size:16px;">HUC 2s, 6s, 8s, 10s, &amp; 12s, define the drainage Regions, Subregions, Basins, Subbasins, Watersheds and Subwatersheds, respectively, across the United States. Their boundaries are defined by hydrologic and topographic criteria that delineate an area of land upstream from a specific point on a river and are determined solely upon science based hydrologic principles, not favoring any administrative boundaries, special projects, or a particular program or agency. The Watershed Boundary Dataset is delineated and georeferenced to the USGS 1:24,000 scale topographic basemap.</span></p><p><span style="font-family:&quot;Avenir Next W01&quot;, &quot;Avenir Next W00&quot;, &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, sans-serif;font-size:16px;">This feature class was built from the WBDHU10 dataset and slightly modified by adding additional fields to the attribute table that identify fish passage survey partners and their timelines within a particular HU10 watershed. The layer serves as a vital tool in fostering collaboration and communication among fish passage partners, aiming to enhance survey and conservation efforts.</span><br></p><div style="font-family:&quot;Avenir Next W01&quot;, &quot;Avenir Next W00&quot;, &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, sans-serif;font-size:16px;"><p></p><div style="font-family:inherit;"><span style="font-size:large;"><font style="font-family:inherit;">Dataset Summary</font></span></div><div style="font-family:inherit;"></div><div style="font-family:inherit;"><strong>Phenomenon Mapped</strong>: Watersheds in the United States, as delineated by the Watershed Boundary Dataset (WBD).</div><div style="font-family:inherit;"><strong>Coordinate System</strong>: NAD83<br></div><div style="font-family:inherit;"><strong>Extent</strong>: Contiguous United States, Alaska, Hawaii, Puerto Rico, Guam, US Virgin Islands, Northern Marianas Islands and American Samoa.</div><div style="font-family:inherit;"><strong>Visible Scale</strong>: Visible at all scales, however USGS recommends this dataset should not be used for scales of 1:24,000 or larger.<br></div><div style="font-family:inherit;"><strong>Source</strong>: United States Geological Survey</div><div style="font-family:inherit;"><strong>Publication Date</strong>: July 27, 2023</div></div>
