Old pipe removal may require less American River flow

Flows on the American River may be lowered and rafting will be excluded one morning later this month to allow for removal of an old water pipe.

The Carmichael Water District on Sept. 13 will take away concrete debris from the south side of the river and remove an existing 33-inch steel water pipeline crossing the river just upstream from Ancil Hoffman Park.

Flows may be reduced from 1,500 cubic feet per second to 1,000 cfs starting in the morning and continuing through 2 p.m. The old pipeline is in the river but is partially exposed.

“This removal of the old pipeline is one the things we are most excited about – to restore the river to its original condition,” said Chris Nelson, Carmichael Water District spokesman.

Also beginning at dawn and continuing until about 1 p.m., watercraft launching in the water will be prohibited beginning at Rossmoor Bar and at other upstream access points, including at Sunrise Boulevard. The watercraft prohibition between those points is needed for safety reasons because heavy equipment will be used that day to remove the pipeline.

Spotters will be on the river to make sure boaters are not on that stretch of river.

The work is part of the American River Pipeline Project. The goal is to provide treated water to Golden State Water Co. and replace contaminated groundwater.
