Overview

The flathead chub, Hybopsis gracilis (Richardson), occurs in the Plains Region of Canada and the United States, in four major drainage systems: Mackenzie River, which discharges into the Arctic Ocean; Saskatchewan River, which discharges into Hudson Bay via Nelson River; and Missouri-Mississippi System and Rio Grande, both draining into the Gulf of Mexico. Each of these systems is occupied in part only. In the Mackenzie Basin, H. gracilis has been reported as far north as Fort Good Hope (Walters, 1955:347). Flathead chubs occur in the Saskatchewan Basin from Alberta eastward to Lake Winnipeg, Manitoba, but have not been found in other streams that flow into Lake Winnipeg (Red River, Brokenhead River and Whitemouth River) nor in Nelson River downstream from Lake Winnipeg. In the Missouri Basin the species occurs more or less continuously from the high plains adjacent to the Rocky Mountains in Montana and Wyoming down the mainstream of the Missouri River to its mouth, and down the mainstream of the Mississippi River as far as Barfield, Arkansas, but not to the Gulf. The species probably attains its greatest abundance in the Missouri Basin, but it is scarce or absent in tributaries north and east of the Missouri mainstream, in the South Platte Basin, and in the central part of the Platte River in Nebraska.

It was a beautiful place. Sunshine. A sparkling blue lake. A happy family. I had a sister named Red. She was funny. A white and red shecat. My father was stone. Nice, happy, and strong. He was a large grey tom with spots. My mother was Sunshine. She was a gold and red she. It started one day. Sunny and happy. Father had gone fishing in the lake, and mother was watching us. I was playing with Red. Suddenly though, i smelled something. It waa strong and musty. Father hadnt smelled it yet. I tried to tell him, but mother put a paw over my mouth and pushed me to the back of the cave under the tree. I saw a large black and white thing creeping up behind father. I watched in horror as he suddenly fell into the lake, the smell of blood reaching us on the quickening breeze. Then it turned. Mother told me to stay silent. It found us anyways. It roared and rushed in. We raced aroun it, into the forest, hoping to get away. It followed us, clumsy paws slipping on the rain, now thundering down. We ran into a hollow and mother turned. She fought bravely, but wasnt strong enough for the badger. She told us to run, and we did. Faster than anyting. We got seperated. I think my sister is still out there. Somewhere.....
