The following chart is a guide for minimum desirable flows in rivers.
Many rivers require a larger flow for whitewater rafts.
Paddle rafts can negoiate easier than oar rafts at low flows. Current river flows are available 24 hours a day. Be aware that flows sometimes vary widely during any given day due to releases, rainfall, or stream runoff. Many times power generation releases are lower on weekends than on weekdays. The basic skills of canoeing, kayaking and whitewater rafting can be obtained through the many schools available.
