As is usual, the Bureau of Reclamation is about to send a blast of spring water down the Trinity River from Lewiston Dam.

This is a good thing, but it’s a time to take warning — the currents of the Trinity River, maybe Humboldt County’s favorite swimming river — can be deadly. People are killed by the current just about every year.

From the Humboldt County Sheriff’s Office:

On May 1st, 2018 there will be an increase in the amount of water released from the Lewiston Dam, which will quickly effect the water levels of the Trinity River. The Sheriff’s Office is concerned that the increase in water levels on the Trinity River will make for unsafe swimming conditions. The increase in water flows is scheduled to continue through May 7th, 2018. Please use extra caution if you choose to be near the Trinity River during this time.

The water release schedule and amounts can be found below.
