Topeka lies on both banks of the Kansas River about 60 miles upriver from the point where the Kansas joins the Missouri River. Two tributaries of the Kansas River, Soldier and Shunganunga Creeks, flow through the city. The valley near Topeka, bordered by rolling prairie uplands of 200 to 300 feet, ranges from 2 to 4 miles in width. Seventy percent of the annual precipitation falls from April through September. Heavy rains pose the threat of flooding, but the construction of dams has reduced the problem. Summers are usually hot, with low humidity and southerly winds; periods of high humidity and oppressively warm temperatures are of short duration. Winter cold spells are seldom prolonged; winter precipitation is often in the form of snow, sleet, or glaze. Severe or disruptive storms occur infrequently.
