Rohnert Park Fishing Derby

Note: The Fishing Derby is organized by volunteers and supported by generous businesses and individuals in the area.


We stock trout every year for the fishing derby between 1000-2000 trout





Rainbow Trout


Size: Typically 10 to 16 inches, though fish from 5 to 8 pounds are commonly caught.

Where Found: Native to streams of the West Coast, rainbows have been stocked in cold streams and lakes across the continent. They also thrive in the Great Lakes.

Rainbow trout are active feeders that strike small spinners and spoons, worms, and artificial baits like Power Nuggets. They’re also prized by fly-fishermen, as their keen eyesight demands careful presentations and their exciting runs and leaps make for extreme excitement.



If you catch a fish at Roberts Lake, take a picture of it and send it to us at with your fishing story and we will post it on our web site here
