***STAGE 2 MANDATORY WATER CONSERVATION IN EFFECT***

Our region just experience the third driest water year on record over the last 127 years.  As of August 4, 2022, Lake Sonoma storage is at 50.5% of water supply capacity and Lake Mendocino is at 62.8%.  Sonoma Water and the City of Rohnert Park are continuously monitoring the water supply conditions.  For more information about the impacts of low rainfall on our water supply, visit www.sonomawater.org/current-water-supply-levels 

In the long run, even accounting for dry years, Rohnert Park’s water supply can meet the needs of our current residents and the growth we’re seeing with new housing.

Stage 2 Mandatory Water Conservation Measures

Frequently Asked Questions
  1. Why are we building new housing during a drought?

    There is a critical shortage of housing in Sonoma County and residents use less water than ever before. Our residents are using 16% less water than compared to 2013, even with the addition of new homes. In addition to expanding the use of recycled water, new housing must have low-flow plumbing and drought tolerant landscaping. Because of these changes and others, in the long run, even accounting for dry years, Rohnert Park’s water supply can meet the needs of our current residents and the new housing.

  2. Where do we get our water?

    We have three sources of water: 45% from the Russian River, 35% from groundwater, and 20% from recycled wastewater. The Sonoma County Water Agency (Sonoma Water) relies on the Russian River and two reservoirs, Lake Sonoma and Lake Mendocino.

    The recycled water irrigates our parks and street medians, landscapes at schools and some businesses, Roberts Lake, Foxtail Golf Course and Sonoma State University.

  3. What is the status of the drought?

    The Sonoma County Water Agency (Sonoma Water) provides water for 600,000 people in Sonoma and Marin counties. Sonoma Water relies on the Russian River and two reservoirs. As of August 4, 2022, Lake Sonoma storage is at 50.5% of capacity and Lake Mendocino is at 62.8%. The state has imposed water restrictions this year. For more information about the impacts of low rainfall on the Russian River this year visit www.sonomawater.org/current-water-supply-levels.

  4. Is the City's water supply enough to get us through the drought?

    Yes, we have enough water to get us through the drought. In the long run, even accounting for dry years, Rohnert Park’s water supply can meet the needs of our current and new residents.

  5. Does the City have a Water Shortage Contingency Plan?                                                         Yes, we do! The City of Rohnert Park has a water contingency plan. A 2022 update of Rohnert Park's Water Shortage Contingency Plan (WSCP) can be found here.  

  6. If we have enough water to get us through the drought, why are we focused on conserving?

    The state’s water restrictions are based on the overall state and regional situations. The state does not account for local conditions such as those in Rohnert Park, where we have enough water.

  7. What is the City doing to save water?

    The City is taking several steps including:

    1. Promoting water conservation messaging.
    2. Making it easier to report water waste on the City's website and Reach Rohnert Park app.
    3. Increasing enforcement against those who waste water. We initially place a door hanger to help educate the water water, and then issue fines if problems continue.
    4. Offering rebates for low-flow toilets and clothes washers, and giving away low-flow shower heads, faucet aerators and water-saving nozzles.
    5. Offering Cash for Grass which provides a $1 per square foot rebate, up to 1,000 square feet of lawn removed.
  8. What can I do to help save water?

    Irrigation accounts for approximately 50% of summertime water use. By turning off irrigation during the winter and conserving water in the warmer months, we can achieve our community-wide 20% water savings goal.

    • Purchase a front-load washing machine and/or high efficiency toilet.
    • Run the dishwasher and clothes washer with full loads only.
    • Consider replacing your lawn with a low-water use alternative landscape. The City of Rohnert Park is offering $1 per square foot rebate through our Cash for Grass program.
