Zebra mussels have been found in Wilson Lake, making it the western-most lake with the aquatic pest.

The owner of Marine Specialty in Wilson was working on a boat from Wilson Reservoir when he noticed zebra mussels on the boat hull. He notified fisheries biologist Tommie Berger and the U.S. Army Corps of Engineers. Berger soon discovered live zebra mussels in Wilson Reservoir, and marina staff found them attached to other boats at the lake.

Wilson is a 9,000-acre impoundment on the Saline River. Downstream reservoirs, such as Milford near Junction City, are now at risk if the mussels are carried in the Saline.

Because of its isolation from other infested waters, Wilson's infestation is likely the result of transport by lake users.
