Welcome to Divide Environmental, Mapping, and Fishing (DEM). DEM provides geospatial and environmental services as well as guided fly fishing.  I work and live in Grand County, Colorado where I am passionate about conserving the natural places that make Colorado great.

Geospatial services include map creation and spatial analysis for various natural resources needs, especially water.

Environmental services include water quality sampling and aquatic macroinvertebrate (bug) sampling to assess aquatic health.

Guided fly fishing services include guided fly fishing trips for up to 3 people (ages 10 and up).    We will walk and wade small rivers and streams in and around the west side of Rocky Mountain National Park near the town of Grand Lake.  My approach to taking people fly fishing is not to find a trophy, but is focused on teaching people how to fly fish and about the fish and their habitat.
