At Rueter-Hess Reservoir in Douglas County, Colorado, the county describes a limited use for electric trolling motors. Before buying a motor for this location, start with the activity. A seller can confirm fit on your board and still leave the main access question unanswered.
Check whether your planned use qualifies
The Douglas County Rueter-Hess FAQ describes permission for certain approved craft, including paddleboards, to use electric trolling motors for fishing. It says non-fishing use of those motors is prohibited. If your plan is powered recreational paddling without fishing, ask the reservoir operator about your plan before treating the site as a suitable place to use the motor.
The current reservoir rules, effective May 1, 2026, specify that a permitted trolling motor must be hand-operated and detachable. They list a maximum thrust of 55 pounds, a 24-inch shaft limit and a 14-foot watercraft limit. Section 13 separately prohibits electric outboard motors and craft with one mounted. The FAQ describes the shaft limit in relation to the waterline. Take the maker’s specifications for the motor you are considering and describe the actual control and attachment. Ask the reservoir operator how it evaluates your specific equipment if the maker does not give the information in the same format.
Check the launch and inspection before committing
The county’s reservoir activities page is a separate starting point for paddling access and current site information. For a craft using a trolling motor, the county rules require Colorado Parks and Wildlife registration and a valid aquatic nuisance species stamp. They also address the inspection at arrival, required safety gear and age limits. Operators are generally 18 or older, with an approved boating safety course required for ages 14–17 under the stated exception. The FAQ says water fishing depends on the reservoir being open to watercraft and describes shore fishing after November 1 until ice forms. Ask the responsible office what you must show on arrival and which watercraft opening dates, launch conditions and inspection requirements apply to your outing. Obtain those answers from the current published site guidance or staff.
Keep a one-page record of the board, motor, mounting system, published thrust, below-waterline dimension and intended activity. Send the operator the details it asks for. Confirm whether it considers the entire arrangement within the permitted category. Do the equipment fit check separately with the board and motor makers.
