Former WSU professor M.A. Monem will give a presentation on clean boating and how the Oak Harbor City Marina became a Certified Clean Marina from 6 to 7 p.m. Aug. 15 at Oak Harbor City Hall. Marinas share many of the same pollution problems that neighborhoods have on shore, plus a few specific to the marine environment. Monem will explain how the marina staff worked closely with Beach Watchers and Power Squadron volunteers to reduce toxins entering Puget Sound. Discover how they continue to monitor water quality and promote safe fishing and crabbing practices among boaters.
