Diamond Lake has been stocked with tiger and brown trout. These fish are intended to assist in controlling illegally introduced tui chub. These trout are catch-and-release only and need to be released immediately and unharmed if caught.

As part of the 2016 regulation simplification process, Diamond Lake is now back to the Southwest Zone regulation of 5 rainbow trout per day.
