Neighborhood Ground Water Network

Sponsored by
Oregon Water Resources Department and OSU Extension / Oregon Sea Grant 

A Pilot Program - July 1, 2008 to June 30, 2009
The Neighborhood Ground Water Network was a one-year pilot program held in the Eola Hills, northwest of Salem, to teach community members how to measure the water level in their wells while informing them about the importance of ground water systems.
During this program, twenty-six participants learned the basics of ground water science, how to measure the water levels in wells, and how to interpret these ground water level measurements. Some of these participants will continue to measure the water levels in their wells, assisted by volunteer program coordinator Rachel Walker.
Education about ground water systems and ground water level measurement has helped these community members become better prepared to care for wells and ground water supplies into the future.

The Eola Hills Ground Water Limited Area
The Eola Hills Ground Water Limited Area (EHGWLA) is one of ten areas adopted in 1992 that restricts water use from the Columbia River Basalt group of aquifers in the Willamette River Basin. This area was designated a Ground Water Limited Area because of the potential for water level declines.

The EHGWLA is an eighty square-mile area located just northwest of Salem, Oregon. The Willamette River makes up the eastern boundary, Highway 22 makes up the southern boundary, Highway 99W makes up the western boundary, and the northern boundary is just above the Yamhill County line.

What is a Ground Water Level Measurement?
A ground water level measurement is a measurement of the depth to water below land surface in a well. The ground water level represents the amount of water storage in the surrounding aquifer. A record of ground water level measurements over a period of time can help you understand how much water is available for use.

Collection of water level measurements in your well will help you identify any declines in water levels before they become a serious problem. Declines in well water levels could be related to well efficiency, variations in ground water recharge and discharge, seasonal fluctuations, or ground water overuse.
Install a measuring tube in your well to make collecting your water level measurements easier.
