Lake Chabot, a pretty reservoir nestled in the tree-studded foothills east of San Leandro in the unincorporated area of Castro Valley, is now a popular location for anglers to pursue largemouth bass, rainbow trout and channel catfish, but it wasn’t always that way.
Built in 1874-75 as a primary drinking water supply for the East Bay, the 315-acre lake was closed to fishing and other recreation for most of its history, 91 years. The lake finally opened for controlled recreational uses in 1965 after legislation was passed in the 1960s. The lake now serves as a standby emergency water supply.
This past year has been an interesting one due to the prolonged drought that has brought the lake level down to very low levels, according to Joe Sullivan, Acting Fisheries Program Manager for the East Bay Regional Park District.
The low water levels and the toxic blue-green algae blooms that occurred at Lake Chabot this summer definitely had an impact on park attendance. Because of this, the park district reduced their fish plants during the very warm summer months.
The good news is that the largemouth bass and other naturally reproducing fisheries appear not to be affected by the toxic algae and low water level.
I haven't had a chance to analyze our annual monitoring data that we collected this past spring and summer, but a first glance shows that fish numbers are staying pretty steady compared to previous years, said Joe Sullivan of the East Bay Regional Park District.
We even had a largemouth bass caught a couple of months ago that was just shy of a lake record, and there's a lot of other monster bass out there, he said. Now that the weather has cooled and we've received some rain, we are back in full swing with the trout plants. Lake Chabot
