More Runoff Being Aimed Towards Groundwater

Dunnigan in the news:

DUNNIGAN, Calif. — As storms have drenched Northern California, water diverted from the swollen Sacramento River has been flowing from a canal and pouring onto 200 acres of farmland. 

For more than a month, the water has spread across fields, forming shallow pools, then percolating slowly into the earth. 

This farm northwest of Sacramento, which has previously produced rice, is being used to replenish groundwater. It’s one of a growing number of sites across the Central Valley where landowners and local water managers are using farmland to take advantage of this year’s heavy rain and snow by capturing water and putting it underground. 

Once applied to the fields near the town of Dunnigan, the water quickly sinks into the soil and makes its way through sediment to the aquifer. Measurements in nearby wells show that groundwater levels have risen. 

“Within a matter of a couple of days, we see improvement in the water table,” said David Schaad, a farmer and president of the Dunnigan Water District. “It’s wonderful to see.”
