Try chicken livers or worms for catfish. You can access the marsh by boat at the North Dike, Catfish Paradise, and Five-Mile Landing. The cold weather has slowed the bite and access to the marsh is difficult due to low water levels. The last report I received said that launching at North Dike was extremely difficult. For more information on the marsh, contact the Havasu National Wildlife Refuge at (760) 326-3853 or go to http://www.fws.gov/southwest/refuges/arizona/havasu/index.html.
