ODF High Aquatic Potential Stream Data
Click on the map to download HAP stream data (mouse over to see the area name)
High Aquatic Potential (HAP) reaches are defined as having low gradient (≤6%) and wide valleys as predicted with the use of Digital Elevation Models (DEMs). The available DEM data was not considered accurate enough to predict valley width index, but field data indicated a high likelihood of low gradient channels and wide valleys occurring coincidentally. A stream reach may have “potential” to provide high quality habitat but may not currently have high quality habitat present.
All of the HAP Stream data is current as of: March 2011. 
HAP stream reaches are intended to help ODF Stewardship Foresters, forest landowners and other users to identify stream reaches in which recruitment of large woody debris is most likely to be effective at enhancing habitat for salmonids.
