Since 1908 the Portland Water District has been caring for Sebago Lake and
educating lake residents and tourists about lake friendly practices.
Because of these efforts, Sebago Lake remains as pristine as it was
100 years ago despite development and increased recreation.
10 Easy Ways To Keep It That Way!
For many people Sebago Lake means fun: boating, swimming, fishing and more.
For 200,000 people in Greater Portland, Sebago Lake is drinking water.
BOAT: Clean your boat while on dry land, away from the lake.
If your boat has been in other lakes, it could be carrying small
organisms or invasive plants (milfoil or zebra mussels, for example)
that would wreak havoc on the ecosystem of the lake.
- MAKE SURE YOUR BOAT IS RUNNING PROPERLY: If you notice
an oil slick behind your engine, get the leak repaired.
- SLOW DOWN: Prevent soil erosion by observing the speed
limits when close to the shoreline and along the Songo River.
- DONíT DUMP GARBAGE IN THE LAKE OR ON SHORE: Use trash bags
to dispose of your food scraps, bottles, cans and other trash.
- DISPOSE OF SEWAGE APPROPRIATELY: Empty your holding tank
or port-a-potty in a suitable disposal area on land.
- SCOOP POOP: If you have a pet, clean up after it. Pet wastes
can carry bacteria that transmit ear, eye, and throat infections
into the water.
- USE LAKE SAFE SOAPS: Use non-phosphate laundry soaps (required
by Maine law).
- DONíT USE THE LAKE AS A BATHTUB: Donít bathe or wash your
hair in the lake.
- PUMP YOUR SEPTIC TANK: Have your septic tank pumped frequently-
four to five years for seasonal homes, two to three years for year-round
COLOR THE LAKE GREEN: Maintain plants, trees, and forest duff
on the property to filter out pollution and prevent erosion. Walk
on footpaths to avoid destroying vegetation. Erosion washes phosphorus
into the lake, which feeds algae and turns the lake green.
