Rules at a glance
What this means in practice
A no-motor listing is the strictest class on the books. It is not just about gasoline: mounting any motor, including a small electric trolling unit, puts you outside the rule on Green Lake. Whether a motor may stay attached-but-unused varies by agency — ask City of Seattle before assuming.
In practice, Green Lake is paddle water: kayaks, canoes, jon boats under oars, and float tubes. Anglers who want to cover water rig drift socks and plan around the wind instead of a motor — position upwind and work the fishable banks on the drift.
Worth knowing about Green Lake: Seattle Municipal Code 16.44.020 prohibits motor-powered vessels on Green Lake (as well as Haller Lake and Bitter Lake); exceptions apply only to patrol or rescue craft, emergencies, and vessels engaged in an authorized restricted activity..
