The Lake Havasu National Refuge Complex has created a safety zone that is anticipated to reduce the likelihood of boat collisions in the Havasu National Wildlife Refuge at the Interstate 40 Bridge on the Colorado River.

The expansion of commercial development at the Topock 66 Marina is expected to greatly increase boating traffic in the area. Safety concerns had been expressed by the Arizona Game and Fish Department and Lake Havasu Marine Association.

A No Wake Zone has been created with two boundary lines of regulatory buoys approximately 700 feet north and 900 feet south of the I-40 Bridge. Watercraft operators are required to be at wake-less speed throughout the zone, which includes the waterway to and around the Topock 66 Marina.
