Investigators are still trying to determine what led to a major fish kill in Fremont this weekend. Between 3,000 and 5,000 fish were found dead in a segment of Alameda Creek between Mission Boulevard and the train overpass in Niles.
The fish apparently died due to lack of oxygen in the water, but investigators are still trying to determine why the oxygen levels had decreased, said Paul Piraino of the Alameda County Water District. Possible explanations are runoff from the first storm of the season Friday night or a pipe failure at Dublin San Ramon Services district which resulted in a discharge that flowed into Alameda Creek.
Tests should be completed on Thursday.
