 Boater Survey Forms

PDF IconInstructions 15 KB

This is the most commonly used survey form. Individual boaters are contacted directly. This form is used by interviewers to record information gathered from individual boaters regarding their movements, boat usage, storage, and their knowledge of zebra mussels.

 This form is typically left on the windshield of unattended vehicles with boat trailers. Boaters are asked to fill in the forms at their leisure and return them in a self-addressed, stamped envelope provided. 

 Parked boat trailers are counted and then recorded on this form. Counts are typically performed near boat ramps or rest-stop areas.
 Boat trailers pulled in traffic are counted on highways, typically near boarder crossings. The information gathered is recorded on this form.
