The large prairie lying in range five west is usually called Blakes Prairie; and the long narrow one extending from Lancaster nearly to Potosi is called Bois Prairie. English Prairie lies at the north east corner of the county, extending into Iowa.

Platte river (Moschoca-"always full" of the Indians) is the largest stream within the county, running principally in range two west, and entering the Mississippi two miles above Sinipee. It is said to be navigable for steam boats for six miles. Its tributaries are Little Platte, French Creek, Huglans creek, & Block House Creek.

Grant river is said to be navigable twelve miles above its mouth at Potosi. It has numerous small branches, among them Bois creek, Pigeon creek, and Rattlesnake creek.

Blue river is a stream about twenty miles in length in the north east part of the county, tributary to the Wisconsin. Near its sources are some valuable mines of lead and copper, known as the "Blue river diggings".
