Columbia FWCO employees Brian Elkington, Jake Norman, and Sara Marso teamed up with employees of Squaw Creek NWR to sample the Silver Lake fishery at Swan Lake NWR.  We also assisted in creating a bathymetric map of Silver Lake.  Swan Lake NWR is in Chariton County near the town of Sumner, Missouri.  The refuge was established in 1937 and is best known for its wetland habitat used by waterfowl during their spring and fall migrations.  This is the first time the fishery has been sampled since 1996.

Sampling consisted of experimental gillnets 100 feet long and fyke nets of two different sizes, medium and large.  We also used a handheld Trimble global positioning system (GPS) to collect the bathymetric map data.  Gillnets were set in open water near submerged structure. Fyke nets were anchored to shore and strung away from the beach to create a “road block” and direct fish into the basket were they became trapped.  The most common species of fish were shortnose gar, freshwater drum, and white crappie.  The most surprising catch was the modest amount of keeper size white crappie.
