Cedar River Water Flow Rates on the Cedar River – Charles City
The first feature, Dam Drop, at the levels mentioned below, allows for endless front/back surfing and spins. At lower flows one can easily stand up surf it.
The second feature, Doc’s Drop, is a semi-retentive, powerful rodeo style hole. Advanced boaters should be able to perform most freestyle moves here especially at 1400 – 1900 cfs.
The third drop, Exit Exam, is not as powerfull as Doc’s but many freestyle moves are possible.
