The Linnwood water purification plant is operated by the Milwaukee Water Works. It has 32 filters and the capacity to treat 275 million gallons per day. Water for the Linnwood Plant is drawn from an intake 6,565 feet from shore, five miles north of the Milwaukee harbor, at a point where Lake Michigan is 67 feet deep. (Source: Milwaukee Water Works)

The Milwaukee Water Works has collected water quality data from its intake on a nearly continuous basis since 1939. This data is a valuable historic record of environmental information, so we offer it here.
