Over the last week the city of Chico has received several calls from nearby residents informing staff members of dead fish floating in Teichert Ponds near Highway 99 in Chico. The Park and Natural Resource Manager for Chico and Butte County Linda Herman confirmed the dead fish being reported are on the back side of the pond near the fresh water area, saying the fish have succumbed to lack of oxygen in the water due to a thick layer of ash that has formed atop many parts of the pond.
