Ground Water Monitoring Network

Ground Water Annual Review

Certain wells throughout the District are sampled at least once yearly for quality and measured at least twice yearly for quantity to help determine trends and the need to study possible phase designation changes. This "Monitoring Network" grows larger each year. In some cases wells are drilled strictly for monitoring purposes and other times existing municipal or irrigation wells are added to the network through agreements with landowners.

Results of network well sampling and measuring are contained in our Ground Water Annual Review, along with other useful information, such as statistics on well permits, well decommissioning, other ground water programs and much more. The Ground Water Annual Review for the previous calendar year is prepared by staff and considered for approval by the NRD Board each February.
