The Missouri Department of Natural Resources thinks it has found the most effective technology solution so far to discourage geese from congregating on the beaches at Lake of the Ozarks State Park. They are using a green concentrated light beam the park purchased about six months ago to deter geese. The device resembles a flashlight and when used, causes the geese to flee and move to another location. Geese on the two public beaches in Lake of the Ozarks State Park, primarily the Grand Glaize site, have been an ongoing problem. The geese add to threat of elevated E. Coli levels after periods of heavy rainfall. Geese tend to return to the same spot year after year. If the Department of Natural Resources can force some or all of the geese to move, the problems created by them gathering along the shoreline will diminish.
