Pacific Power and Light Company operates Boyle Powerhouse for power generation and through this operation navigable flows occur all summer.

Call the public service recording at:  1-800-547-1501


Most guides on the UK refer to the flow in terms of the generators that are running for the day. 1 generator refers to flows from 1200-1800 cfs where 2 generators refers to flows of 2200-3000 cfs. On the lower side of the spring island eddy there is a gauge marked off in terms of generators. Launch when the water level is at the 1 generator mark. It is possible to float the creek to Caldera at base flow however if for some reason the release does not happen you will not be able to continue to the take out.

It takes the release about 1 hour to reach the top of Caldera and consequently the same during ramp down. Keep this in mind when you take time to scout, lunch, play, or resolve incidents. Always keep an eye on the water marks on the rocks. This can give you clues to any operational changes at the power house.
