Heavy rains caused 900 gallons of wastewater to spill out of a manhole near the Penngrove lift station, according to the agency. The lift station is owned by the Penngrove Sanitation Zone, which is operated by the Sonoma County Water Agency.
The water flowed to Lichau Creek, where a biologist from the water agency was dispatched to check for any negative effects to fish and wildlife. None were found, water agency officials said.
