Mapping

Since 2011 the Kenai Watershed Forum has been a leader in updating the USGS National Hydrography Dataset , or NHD. Water is fundamental to our mission and it all begins with knowing where and how accurately depicted our waters are.

Wetlands are regulated under section 404 of the Clean Water Act. Kenai wetlands are mostly in good shape, providing valuable habitat, water quality, and flood control functions. Maintenance is cheaper and easier than repair. “If it ain’t broke, don’t fix it.” Kenai wetlands ain’t broke, and we’d like to keep them that way. In order to do that, a project was created to help understand where wetlands are, and to guide the development of best management practices in order to maintain valuable wetland functions.

We classified and mapped 350,811 acres of wetlands over 809,370 acre project area at a scale of 1:24,000 on Kenai Lowlands, Alaska (43% of the land surface)!

It is estimated that less than half of Alaska’s freshwater salmon habitat is officially documented by the Alaska Department of Fish and Game, and until these streams and lakes are inventoried they will not be afforded certain protections under enacted Alaska Statute 16.05.871, “Protection of Fish and Game.” Additionally, often the actual locations of the streams in this database are inaccurate at the scale used for making decisions on individual parcels. 

While the Alaska Department of Fish and Game is conducting efforts to update existing data and survey for previously undocumented habitat, there remains a vast number of water bodies in need of surveying and habitat use observations. And,

We now have newer technology to more accurately map these streams using a GPS, satellite image interpretation, and observations in the field.  This project preserves salmon habitat through regulatory protection and directs our attention to new stream crossings that often pose potential barriers to salmon migration.

It is believed that less than 50% of the streams, rivers, and lakes actually used by anadromous species in Alaska are protected in the Catalog of Waters
