Friends of the Bill Williams River and Havasu National Wildlife Refuges
Fishing in and around the Bill Williams River and Havasu National Wildlife Refuges offers varied opportunities to try your luck. In the Havasu NWR, you can fish the quiet backwaters of Topock Marsh, or drift the Colorado River from Topock through Topock Gorge to the sorthern upper end of Lake Havasu. Bill Williams NWR offers the opportunity to fish the southern end of Lake Havasu.
Generally, Topock Marsh offers largemouth bass, panfish, catfish, crappie, and carp. The slow-moving waters of the Colorado River from Topock south to the north end of Lake Havasu offer striped bass, catfish, and rainbow trout. Species in Lake Havasu include striped bass, largemouth bass, channel and flathead catfish, and bluegill.
Some native fish may also be encountered. Please use catch-and-release techniques with any native fish captured and report captures to refuge personnel.
State and federal fishing regulations apply when fishing in Topock Marsh, the Colorado River, and Lake Havasu. Please consult the Arizona Game and Fish Department regulations, as well as the Bill Williams River and Havasu NWR websites for more information; links to their websites are provided at the bottom of this page.
