The warmer weather has increased fish activity along the Colorado River. Anglers fishing from shore and docks are catching striped bass and rainbow trout. Striped bass are showing a preference for anchovies and light-colored swimbaits. One angler reported catching an 11-pound striper on an anchovy just south of Casino Row. Trout are biting on yellow and olive-colored jigs and a variety of spinners. Some anglers prefer night crawlers and have reported catching an average of three fish a day.
