Dear Valued MCCSD Customers and Property Owners,
MCCSD is still in the midst of an historic drought. To date we have only recorded 20.43 inches of rain fall for the year. This is the second lowest recorded total in the past 100 years.
MCCSD has a Water Shortage Contingency Plan in effect to help prolong the available water in our shared Mendocino Headlands Aquifer, and help prevent as many wells as possible from going dry. Even with this plan in effect we understand some of you may be running out of water.
According to the WSCP rainfall is the primary tool used to determine a water shortage during winter and spring months. In the dryer summer months, depth-to-water measurements are the primary tool used to determine the recommended Water Shortage Stage.
Due to higher than expected Depth to Water measurements on August 31, 2020, the Mendocino City Community Services District (MCCSD) Board of Directors voted to reduce the Stage 4 Water Shortage Emergency Declaration to Stage 2.
The Stage 4 Water Shortage came with a mandatory 40% reduction in water allotments. The Stage 2 Water Shortage includes a request to voluntarily reduce water usage by 15%. I would ask and remind you all to continue conserving and think about your neighbors.
It is unknown exactly why the water table is slightly above the expected level considering the lack of rain fall. It could be the 40% reduction in allotments really helped, it could be carry over from the heavy rain fall last year, it could be related to better conservation by consumers, it could be related to the COVID-19 pandemic and Shelter in Place Orders. I believe it to be combination of all these factors.
Depth to water measurements continue to decline but not enough to recommend a Stage 3 Water Shortage at this time. We have increased our frequency of depth-to-water measurements. Again we request that you do your best to conserve water, think about your neighbors, and keep us informed if your well does run dry. If you have questions please visit our web site or contact the office.
Due to higher than expected Depth to Water measurements on August 31, 2020, the Mendocino City Community Services District (MCCSD) Board of Directors voted to reduced the Stage 4 Water Shortage Emergency Declaration to Stage 2.
Depth to Water measurements are the primary tool used by MCCSD during the normally dry summer months, according to the Groundwater Shortage Contingency Plan adopted May 11, 2020.
Due to below normal rainfall in Mendocino from January 1 to May 31, 2020, the Mendocino City Community Services District (MCCSD) Board of Directors declared a Stage 4 Water Shortage at the District's June 29, 2020, regular monthly meeting.
The rain year is from October 1 to September 30, and Mendocino receives an average of 40.04 inches of rain annually. This year MCCSD has recorded a total of just 20.43 inches of precipitation since the start of the 2019-20 rain year on October 1, 2019. This is 51% of normal annual rainfall, and is what triggered the Stage 4 Water Shortage Emergency.
Although lower than normal rainfall was recorded from October 1, 2019 through August 31, 2020, higher than expected Depth to Water measurements in our Five Drought Monitoring Wells led to the Stage 2 declaration.
MCCSD will continue to closely monitor Depth to Water measurements and rainfall every month and advise the Board if changes in the Water Shortage Declaration are recommended.
