Water Conservation & Shortage Stages
California Drought Status:
Third year of drought ends as fourth year looms:
- The past 3 years have been the driest in CA history. Nearly all of CA is in a 100% moderate-to-exceptional drought
- Both evaporative demand and lack of precipitation are drivers of the current drought since it began in Oct 2019
- A "three-peat" La Nina winter is forecasted for winter 2022/2023, suggesting continued dry conditions
- Current projections are for a shortage on the Lower Colorado River in 2023; Lake Mead and Lake Powell water levels are nearly 3/4 empty
California Drought Emergency Declared
- California statewide emergency water regulations adopted in May 2021 went into effect in June 2021. Follow this link for an FAQ on the State's water restrictions.
- Owners and managers of commercial, industrial, and institutional properties (which includes HOA's) must not use potable water for irrigating non-functional turf. Please see the State's FAQ on what this means.
- An HOA cannot issue a fine on a homeowner for reducing or eliminating the watering of vegetation of lawns during a state or locally-declared drought emergency (per Civil Code section 4735(c)). HOA's may still apply landscaping rules within the governing documents that establish reasonable design, maintenance, and quality restrictions. (State's HOA FAQ)
The District's Best Management Practices (BMPs) are in effect at all times and are permanent. The following is a summarized list (full text of Ordinance 2021-05-05):
- Water landscapes during the cooler times of the day, between 6 p.m. and 8 a.m. (exceptions for watering with a bucket; a hose with a shutoff nozzle; or with drip irrigation)
- No irrigation during or after rainfall for 48 hours
- Limit incidental runoff from irrigation
- No washing down of impervious surfaces (exception for sanitary hazards)
- Washing of vehicles permissible with use of hand-held bucket or hand-held hose equipped with a shut-off nozzle
- Obligation to fix leaks within 7 days
- Decorative water features must be equipped with a water re-circulating device
- No installation of single-pass cooling systems
- No irrigating turf with potable water on public medians
The following are the stages of water shortage which may be declared by the District's Board of Directors to respond to a water shortage condition. Click each Stage on the left for a summary of the water shortage response actions that may be implemented.
|Water Shortage Stage||Water Shortage Condition||Percent Shortage|
|Stage 1||Water Shortage Warning||1 to 10%|
|Stage 2||Moderate Water Shortage||up to 20%|
|Stage 3||Significant Water Shortage||up to 30%|
|Stage 4||Severe Water Shortage||up to 40%|
|Stage 5||Critical Water Shortage||up to 50%|
|Stage 6||Emergency Water Shortage|

In May of 2021, the District updated its Water Conservation Ordinance and Water Shortage Contingency Plan. The Water Shortage Contingency Plan provides guidance on what water supply shortage actions the District may implement in the event of a water shortage condition.
The District's Ordinance 2021-05-05 establishes Permanent Water Conservation Best Management Practices (BMPs) that are in effect at all times in the District's service area. These BMPs are intended to promote water conservation as a permanent way of life and prevent the waste of water, even during years of normal or above normal rainfall and water supply.
Summarized above are the year-round Water Conservation BMPs as well as the water shortage actions for any given declared water shortage stage. The specific text can be found in the documents on the top right of this page.
