Drought Update


On July 20, 2021, City Council updated our Moderate Water Shortage Regulations. City of Napa water customers must adhere to Water Waste Prohibitions in accordance with Napa Municipal Code Section 13.10 as we seek a 20% community-wide demand reduction.

NEvery Drop Counto doubt we're in a drought. Since the last major statewide drought ended about five years ago, the winters of 2016-17 and 2018-19 were two of the wettest in recorded history. Unfortunately, the two winters that followed have been dry (2019-20) and critically dry (2020-21). Lack of precipitation in the Feather River watershed and below average snowpack in the Sierras have put a strain on our imported State Water Project supply. Locally, less than 10 inches of rain has fallen in our key watersheds. Lake Hennessey is at an abnormally low level this summer. In the drought of 2015 and 2016 our community reduced daily water usage by changing outside irrigation habits. We need to do it again.


Our GOAL: 20% reduction from last year's summer/fall water use.

Some easy steps to help reach this goal:

  • Reduce lawn watering to two days per week to meet the updated regulations:
    • Even-numbered addresses may irrigate on Mondays and Thursdays only.
    • Odd-numbered addresses may irrigate on Tuesdays and Fridays only.
  • As always, avoid overspray and runoff. Sidewalks do not need to be watered.
  • Hand water dry areas rather than running sprinklers to excess.


How are we doing?

Lake Hennessey Level vs Consumption

Small changes around the home can make a big difference. Save water now by:

  • Learning how to reset your controller. Remember to limit lawn watering to the prescribed two days per week through October.
  • Applying mulch to planted areas to retain moisture in the soil.
  • Running only full loads of laundry or dishes.
  • When loading the dishwasher, skip rinsing and scrape food scraps into a compost bin instead of using the garbage disposal.
  • Turning off the water while you lather with soap, shave, or brush your teeth.
  • Not using the toilet as a trash can. Never flush wipes, tissues, masks, gloves, or paper towels.
  • Replacing an old inefficient toilet (>30 years old) with a new high-efficiency model.
  • Using a broom instead of a hose to clean off patios, decks, sidewalks, and driveways.
  • Finding and fixing leaks!
  • Asking our Water Conservation Specialist for a free Water-Wise Home Survey.
  • Converting your high-water-use turfgrass to climate-appropriate water-wise plants. Take advantage of our popular "Cash For Grass" Rebate Program.
