Moloka‘i Irrigation System Water Level

CURRENT WATER LEVELS 

NOTICE:  10% VOLUNTARY NON-HOMESTEAD WATER CONSERVATION 

March 5, 2025

The Moloka‘i Irrigation System (MIS) is experiencing a low storage supply of water in the reservoir. This is attributed to the hot and dry conditions on the Island of Moloka‘i experienced in recent years, and especially through 2024. The reservoir is presently at 25.5 feet and containing approximately 602.5 million gallons. At this same time last year, the reservoir was at 27.25 feet and 651.25 million gallons.

While we are not in a state of emergency conditions at this time, the program urges irrigation system users to be cognizant of the situation and prepare for possible reductions in the availability of water from the MIS.  We request that all users immediately begin voluntary reductions in monthly water consumption by at least 10%.

In the event the reservoir level continues its downward trend, there may be a future need to implement additional water conservation measures including, but not limited to, mandatory 10%, 20%, or 30% reduction in water use, periodic shut-off of water distribution, surcharges for overuse, and/or termination of water service to those users not in compliance with the conservation measures.

Please be aware that homestead users are not subject to the mandatory restrictions until such time that homestead usage, based on actual need, as defined, reaches two thirds of the water developed in the first phase of the MIS construction.
