Sebago Lake Protection - Summer 2026 - Portland Water District

Sebago Lake serves as the drinking water supply for nearly 1/6 of Maine’s population as well as hundreds of thousands of visitors each year. Not only is it a source of drinking water, but it is a treasured place to those who live, work, and play on its shores and in its waters. Protecting this resource ensures its dependability as high-quality drinking water and all its uses.

This edition features interesting results from archaeology on St. Joseph’s campus, an interview with Sebago Clean Waters Partnership Director, info on navigating regulations when removing trees, grants for Sebago Lake shorefront property owners, and more topics of interest to those who enjoy and care for Sebago Lake!

Our recent newsletter is available in limited copies at an outdoor receptacle at our Sebago Lake Protection Office in Standish, located at 1 White Rock Road and electronically here.

Add Native Plants to Your Yard

One of the best ways to enhance your shorefront property and help protect water quality is by planting trees, shrubs, and perennials that are native to Maine. We’re partnering with Maine Audubon to bring the native plants closer to you with a Native Plants Pop-up Sale in Standish.
