Mandatory Boat Inspections for ANS

To boat on the reservoir, an aquatic nuisance species (ANS) stamp, current boat registration and a pre-launch boat inspection at the boat ramp is required.

Vessels and other floating devices that are both hand-launched and human-powered are exempt from mandatory ANS inspections. Although, the public is strongly encouraged to self-inspect their watercrafts, boots, waders, and fishing equipment by making sure that all equipment is clean, drained, and dry. For instructions, see Clean Your Gear.
