From the early days of scientists visualizing the environment in new ways from hot air balloons to the modern tools of aerial drones, mapping gives us an opportunity to view our world in a way no other technology can. It helps us visualize data in unique and informative ways, it helps us understand spatial and temporal relationships, and allows us the opportunity to look at the world around us, and our relationship with it, in ways which can span from scientific to artistic.

Maps and their symbols are embedded in our society – just take a look around next time you go for a drive, all those road signs originated from “cartography”, the study and practice of. making maps. Cartography supports all of the Kenai Watershed Forum’s endeavors, including research, restoration, and education, and we maintain an exhaustive mapping database through the use of ESRI’s Geographic Information System (GIS).

Project Highlights

National Hydrography Dataset

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. In partnership with government agencies, our efforts culminated with high-resolution NHD data for the Kenai Peninsula Borough region now incorporated into USGS databases.

Wetland Assessments

Areas mapped as wetlands (blue) in the project area (yellow). Wetlands occupy 41% of the project area.

Wetlands are regulated under section 404 of the Clean Water Act. Kenai wetlands provide valuable habitat, water quality, and flood control functions. Maintenance is cheaper and easier than repair, and “if it ain’t broke, don’t fix it.” Tpo a large degree, Kenai wetlands “ain’t broke”, and we’d like to keep them that way. We work to help understand where wetlands are, and to guide the development of best management practices in order to maintain valuable wetland functions. To read more about our wetlands mapping efforts and access, data visit the Cook Inlet Wetlands section of our webpage.

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)!

Anadromous Waters Catalog

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 are 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. These habitats also serve a critical role

While the Alaska Department of Fish and Game and other other organizations are 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.

We now have newer technology to more accurately map these streams using high-accuracy GPS, satellite image interpretation, and observations in the field.  These efforts help preserve salmon habitat through regulatory protection and directs our attention to new stream crossings that often pose potential barriers to salmon migration.
