From The Olympian:

Tumwater's city attorney will file a motion in Thurston County Superior Court this morning to join Olympia in its quest for water rights at the former Olympia brewery.

Tumwater City Council members decided to take the legal action at a special meeting Thursday night. The motion also will contest part of the condemnation Olympia filed last week, which lays claim to some of Tumwater's municipal water rights, about 400 acre-feet in the Tumwater Valley that the city bought from the brewery to irrigate its golf course.

The move is not meant to be combative toward Olympia, Tumwater Mayor Ralph Osgood said, adding that he had spoken with Olympia Mayor Mark Foutch about the plan.

An acre-foot is the amount of water it takes to cover one acre 1 foot deep (326,851 gallons). So, that's about 130,740,400 gallons per year.
