River Regatta 2015Scores of visitors are pouring into the tri-state area for the annual regatta. Bullhead City Manager Toby Cotter says it’s important for participants and other interested parties to accept and read an information booklet provided at the point of registration. Cotter said the booklets provide important public safety and transportation information for Saturday’s big event. He said it appears about 28,000 people will enjoy Saturday’s eight-mile float down the Colorado River.
