Table 5-9. Mean elevation of instream woody habitats (exposed roots <strong>and</strong> snags) at<br />
fourteen instream habitat cross-section sites, corresponding flows at the USGS Braden<br />
River near Lorraine gage site required for inundation of the mean elevations, <strong>and</strong><br />
maximum percent-of-flow reductions associated with less than a 15% reduction in the<br />
number of days flow sufficient to inundate the mean habitat elevations for two benchmark<br />
periods..<br />
