Hot summer weather leads people to water and water sports. One of the most popular summer activities is white water rafting. The Colorado Tourism Office is a great source of information on rafting opportunities in Colorado. Rafting safety information can be found on the Colorado State Parks website. If you live for rafting or kayaking, you may be interested in stream flow data available from the Colorado Division of Water Resources. Their database will show peak waterflow and current water level information for Colorado streams and rivers by section.
