Agency won't save water to prevent another big fish kill

TRINITY RIVER -- Get ready for a new Trinity River.

Flows downriver in the coming weeks should be the highest since Trinity Dam was built more than 40 years ago, as a Clinton-era restoration plan is put into place after years of litigation.

The Bureau of Reclamation decided against saving some of the Trinity's water to send downstream in the fall to prevent another fish kill on the lower Klamath River.

Instead, the vast majority of the water will be released in May, June and July, giving the Trinity strong currents that it hasn't had in decades, with the exception of flood years.

Flows have stayed around 300 cubic feet per second (cfs) since October. By today, they should crank up to 2,000 cfs and by May 10 should peak at 7,000 cfs.

Go with the flow Scheduled flows for the Trinity, in cubic feet per second: Today: 2,000 cfs Saturday: 2,500 cfs May 6: 4,500 cfs May 8: 6,000 cfs May 10: 7,000 cfs May 14: 6,000 cfs May 19: 4,500 cfs May 25: 3,000 cfs June 8: 2,000 cfs July 22: 450 cfs

At that level, the water will be so high that just 12 seconds of flow would be enough to supply the towns of Weaverville and Douglas City for one day. The flows will remain at 7,000 cfs for four days before slowly dropping back down.

Until this year, flows have been limited to 6,000 cfs. In future years, they could go a lot higher -- up to 11,000 cfs in very wet seasons.

Ecologically, the idea is to scour clean the river's gravel beds and flush juvenile salmon out toward the ocean. The flows might also be good news for rafters.

But those who are used to a tame Trinity had better beware, the bureau warns.

"That's an awful lot of water," said bureau spokesman Jeff McCracken. "It's going to be moving very fast, and it's going to be very cold."

Department of Interior officials created a controversy earlier this month when they asked an advisory council to consider holding back some water to help adult salmon swimming upstream in the fall. In 2002, at least 33,000 of those fish died on the lower Klamath below its merger with Trinity due in part to low flows.

Trinity River advocates struck back, saying the proposal would ignore years of scientific study and would "prostitute" the Trinity for political purposes.

The advisory council rejected the fall flows, and the bureau published a flow schedule that supporters say is much closer to the vision of the original restoration plan.

Historically, the majority of the Trinity's water has been diverted to farms in the Central Valley. The restoration plan was challenged in court but ultimately upheld last year.

Crews are rebuilding or strengthening four bridges to withstand higher flows, and one home eventually will have to be moved.

Rafters are gearing up for what the Trinity River Rafting Co. on its Web site calls "exceptional flows."

Marc Rowley of the Bigfoot Rafting Co. in Willow Creek says the higher flows are good for business.

But the swift currents are probably best for those with experience, Rowley said. Flows at 7,000 cfs are the equivalent of 52,500 gallons per second shooting through the channel.

"It's got to be the right group of rafters," he said. "It's certainly not for average family travelers. The rapids can get quite turbulent."
