Industrial Powerline Threatens Carson Lake Bird Habitat

Carson Lake is a distinct wetland in a remote corner of northwest Garfield county, and one of the few such places in this eastern sandhills county. More than twenty years ago, upon initiating a personal project to survey distinctive lake places in the Sand Hills region, this locality was one of the first places visited. It became a favorite site to enjoy the local wildbirds because of the number and diversity of species.

Total: 28 visits during all seasons of the year, but especially during the breeding season

The land-owner gave permission, so there were many nights when my truck was parked on the west bank of the place, during which the lake setting was scanned repeatedly with a spotting scope to observe and appreciate the abundant bird life. Often, the respite from driving continued until the next morning, when the song of the birds could especially be enjoyed. This is a unique place for birds among the hills.

Now, about 25 years after my first visits, a state utility company wants to place an industrial powerline along the south side of the lake setting. The officials know nothing of the wildbirds associated with this distinct place. They have indicated a line on a map to indicate the routing for the so-called r-project. The corridor is along the southern edge of the lake. The utility company could have just as easily drawn their route a mile southward, along the county road, but obviously preferred to run the line across a grassland/wetland terrain, and most notably, too near to the lake.

The utility company has not presented any rationale about how they decided upon this particular route. It does not make sense to place a hazardous powerline so close to a wetland used by so many sorts of wild birds.

Lake Features

Carson Lake is about 400 acres in size with two types of wetlands. The extent and depth of water is highly variable depending on precipitation, and this flux creates a diverse wetland setting that provides a changing habitat. There are additional wetland features — including wet meadows — immediately south of the lake.

Bird Species

This is a tabular summary of the 114 bird species observed at the lake and its surrounding ranchland environs. The value given indicates the total number of birds counted on the visits during the particular year, and gives a rough indication of the extent of occurrence.
