WATER WELL REPORTS (WELL LOGS)
Another useful tool for learning about your local groundwater is the water well report, often called a “well log.” Well logs are prepared by the well driller as required by Oregon water law and they provide information on geologic formations encountered in a well and they list details concerning well design, construction, and yields. They are a basic tool used in checking for groundwater availability.
Oregon Water Resources Department(WRD) has well logs for most of the water wells drilled in Oregon since 1955. However, the likelihood of finding records for wells drilled after 1970 is much higher than for older wells. Well logs are available on the State of Oregon's WRD Website.
From the home page, select “Find a Well Log.” There are numerous ways to query the information but the most useful way is to search under township, range, and section. The data for all of the wells in the section(s) will be displayed on the screen. Contact us with any questions. We are happy to assist.
