Tacoma's Water Supply. 



The city of Tacoma, Washington, has entered into a cooperative agreement with the 

 Forest Service for the protection of the source of its water supply, the watershed of the 

 Green River, which lies within the Rainier National Forest. The two agencies working 

 together will protect this stream from the results of forest destruction by fire or by other 

 agencies.
