To supplement the District’s¬†network of rainfall gauges, our staff oversees the Cooperative Rain Data Collection Program. Through this program, volunteers collect rain gauge data throughout the county.

Volunteers measure and record rainfall depths at the same time each day to develop consistent records of accumulated rainfall. They then forward the data to the District monthly. The District provides a rain gauge and recording materials to eligible volunteers.

Weather and science enthusiasts interested in participating in the program, or anyone with historic data to share, should contact Frank Codd at 510-670-5783 or frankc@acpwa.org.
