The next big-ticket item on the Nevada Irrigation District’s horizon?

Possibly spending $20 million to replace an 8,000-foot concrete canal that runs alongside the Bear River below Combie Reservoir.

The canal burst in July, washing away a section of riverbank and silting up the river before workers patched the 8-foot gash.

NID will shut down the canal Monday – interrupting irrigation service for three days to 850 customers – so workers can clean and spray concrete on the 400-foot section of canal where the failure occurred.

While the canal is shut down, it will be inspected by engineers from the firm of Brown and Caldwell, who will determine the canal’s strength.

“It could be a big problem or it could be a very small problem,” said NID general manager Jim Chatigny.

The engineers should report back to NID within a month. If they conclude that the concrete canal – built in the late 1970s – needs to be replaced, the job could cost about $20 million, Chatigny said.

The outage affects irrigation water customers along the Highway 49 corridor in Nevada and Placer counties and extends westward to the Lincoln area, he said.

The planned outage begins at 5 a.m. Monday and will last until 6:30 a.m. Oct. 3. Water will be out again from the early morning hours of Oct. 7 until early Oct. 8.
