Outdoor Conservation

The community of Mammoth Lakes uses almost 20 million gallons a week for irrigation during our summer months. The Mammoth Community Water District has developed an irrigation schedule to assist in mitigating this increased demand. Please do your part to conserve our water resources; look at our Managing a Water Efficient Lawn page for suggestions on how to lower your outdoor usage.

This graph illustrates that in our service area, over half of the water produced during the summer is used for irrigation. Sierra Star and Snowcreek golf courses irrigate with recycled water and are not included in this water demand data.
