The river is appropriate for novice canoers and kayakers when the water level is low, as it is now with this year's drought. Many sections are no more than knee-deep, which may surprise newcomers because the river is as wide as two football fields in some spots. But it's so shallow paddlers occasionally have to push their boats over sandbars.
And because the state is so flat, the river doesn't move fast, with water dropping only about 2 feet in elevation per mile (about a half-meter per 1.6 kilometers). That makes it safe and easy for family outings, though Calwell recommends passengers be at least 5 years old and paddlers at least 14, accompanied by an adult.
The river gets the most recreational use from spring through mid-October, though canoers and kayakers continue to paddle on warm days in late October and November.
The Kansas River is named after the Kanza or Kaw Indians who once lived along its banks. The waterway begins where the Smoky Hill and Republican rivers join at Junction City near the Fort Riley Army base. It then flows about 170 miles (273 kilometers) eastward taking paddlers through the scenic Flint Hills, two college towns and the state's capital before it dumps into the Missouri River at Kaw Point in Kansas City, Kan.
It was at the confluence of the Kansas and Missouri rivers that the Lewis and Clark expedition camped more than 200 years ago as they journeyed westward to explore the Louisiana Purchase. But prior to a decade ago, the Kansas River had only three public boat-launch areas, with another four or five on tributaries, Calwell said.
With 11 public access areas added since then, the Friends of the Kaw is coming close to its goal of a public boat launch every 10 miles (17 kilometers). Eventually the group hopes to add more at five-mile (8.5 kilometer) intervals. Five-mile stretches are popular among novice paddlers because they take about two hours to complete, not including breaks, compared to three to four hours for 10-mile stretches.
