Parks & Recreation

We are currently accepting applications for seasonal positions at our parks and hydro projects.

Embrace the great outdoors and join our dymanic team, where you’ll be part of a community committeed to maintaining the beauty of our parks.

Tacoma Power Parks are available to you and your family for camping, boating, fishing, water skiing, nature watching and day use. Our four parks are located in western Washington on the shores of lakes formed by our dams, which generate clean, renewable hydroelectric energy.

  • Reserve individual campsites up to nine months in advance for dates between May 15 and Sept. 15. Sites not reserved during that timeframe are available for one-night walk-in stays.
  • Between Sept. 16 and May 14, our individual campsites are walk-in only (first-come, first-served; reservations are not available), except for Dec. 20 – Jan. 1 when our parks are closed. Camping at Mayfield Lake Park is closed between Oct. 16 – April 14.
  • Save money on reservation costs by using our online reservation system. Or, you can call 833-290-8180 to book a spot (for a higher fee). Both offer the same real-time campsite availability.

It’s important to remember that warm air temperatures don’t equal warm water temperatures. Even if it’s hot outside, the water is extremely cold. The farther from shore, the colder the water can be as well.

According to NOAA, cold water drains body heat up to 4 times faster than cold air. Cold shock can be just as severe and dangerous from water temperatures of 50-60F as it is from water at 35F. Even experienced swimmers can quickly lose muscle control.
