News & Announcements
Lake Oswego and the Clackamas River Water Providers are asking our customers to help keep water in the Clackamas River for the fall fish runs. River levels are significantly low right now, so let’s make sure there is enough water for the Coho and Chinook Salmon by reducing or shutting off outdoor watering. Red conservation actions:
- Reducing or shutting down all outdoor watering, spot water when needed
- Taking your car to a commercial carwash which recycles the water
- Shutting off all outdoor water features
- Not letting water run off driveways, sidewalks, or down the street
The more we can conserve, the easier this journey will be for these threatened and endangered salmon species.
Thanks for doing your part to keep water in the Clackamas River!
Interested in learning more about your drinking water? Every drop begins in the Clackamas River — one of Oregon's most pristine water sources.
Discover where your water comes from by signing up to one of our water treatment plant tours! It's a great opportunity to see the process firsthand, meet the team, and deepen your connection to the water you rely on every day.
Tours are held about once a month between spring and summer, take approximately 1 ½ hours and are limited to 15 people per tour.
There is no such thing as a flushable wipe – even the ones that say flushable. “Flushable” wipes cause serious damage to sewer systems and homes because they don’t break down or dissolve, clogging sewer pipes, damaging equipment, and causing expensive repairs for homeowners and our public sewer system.
Do not flush wipes! The only items that should be flushed down the toilet are toilet paper and human waste. Other items, like wipes, should be thrown in the trash.
