Context: They geared us up in wetsuits and splash jackets to ward off the cold temps which are compounded by cold water . The river was running at about 820 cfs ( cubic feet per second ) but had topped out this year at 3600 cfs and will go as low as 250 cfs ( 1 cfs is the amount of water equivalent of the size of 1 basketball ) . At 3500 cfs the water runs very fast but most of the technical aspects of the river ( i.e. boulders in the middle ) are covered up , so while its a fast run , its not as technical .
