TO:                               Customers of the Waimea Irrigation System
FROM:                        Waimea Irrigation System
SUBJECT:                  Mandatory Water Conservation

As a result of the low rainfall condition over the past several months, the Waimea Irrigation System has commenced pumping water from the Puu Pulehu Reservoir to the Puukapu 60 MG Reservoir for the past several weeks.  According to the National Weather Service’s hydrology reports, Kamuela Upper gage reported 11% of normal rainfall and Kamuela I reported a mere 5% of normal.  The Kawainui Stream gage reported only 45% of normal flow.

Effective Monday, November 4, 2013, an emergency declaration was announced by the Waimea Irrigation System and requests your cooperation in implementing a mandatory 10% reduction in irrigation water consumption until further notice.

In accordance with §4-157-4, Hawaii Administrative Rules, the Administrator and Chief Engineer may declare emergency conditions and implement conservation measures to forestall a water shortage or interruptions in water service.

The Department of Agriculture has established a “link” to this webpage so water users may track the irrigation system’s availability of irrigation water.  The link provides the daily reservoir level, provides National Weather Service information and staff’s comments on the condition of the irrigation system.

SUBJECT:      Strong El Nino – Winter 2015 and Spring 2016

The National Weather Service is projecting a 90% chance that the current El Nino will continue through the winter and an 80% chance of El Nino continuing through Spring 2016.  El Nino events are often accompanied by significant lower than normal rainfall during the winter months.  Although reservoir levels are currently high, a prolonged dry spell can quickly bring the levels down.  Therefore, the Department of Agriculture strongly suggests that all irrigation system customers review your plans for plantings this winter and next spring, keeping in mind that irrigation water service may be affected by the projected effects of the El Nino should conservation measures be implemented.

Should you have any questions, please feel free to contact Glenn Okamoto, Infrastructure Manager at (808) 973-9436 or Randy Teruya, Agricultural Asset Manager at (808) 973-9478.
