Freshwater Monster of Idaho.
Etymology: The name was chosen by local residents in 1954.
Variant names: McCall serpent, Slimy Slim.
Physical description: Length, 20-40 feet. Black to dark green. Smooth skin, sometimes described as shell-like or rubbery. Head like a camel's. Ears like a bulldog's. Blunt snout. Long neck. Three to four dorsal humps, the middle one being the largest. Large, flat, finned tail. Behavior: Swims with vertical undulations. Distribution: Payette Lake, Idaho. Significant sightings: In July 1944, Thomas Rogers and others saw a 35-foot-long animal with a head like that of a "snub-nosed crocodile" undulating through the water.
In 1952, Pauline Miller watched a bulky, three-humped animal with a finned tail floating in the McCall city dock. It had a distinct, scaly, shell-like covering on the top.
On June 12, 1977, Cathleen B. Millburn and Doug Crowther were fishing in a boat off Cougar Bay when they noticed a disturbance in the water and saw three swiftly moving humps. Possible explanations:
(1) The White sturgeon (Acipenser transmontanus) is the largest freshwater fish in North America, growing to 20 feet long. However, there have been no reports of a dorsal fin, and sturgeon are not known in Payette Lake.
(2) The Northern elephant seal (Mirounga angustirostris) matches the size, but unfortunately, this is a marine mammal. Sources: "Slimy Slim in Idaho's Payette Lake,"
