Packwood Lake is a freshwater lake in the Gifford Pinchot National Forest in the Cascade Mountains of Washington. It is located near the town of Packwood and is a popular day hiking and overnight camping area. The southern half of the lake lies within the Goat Rocks Wilderness area. ==Geology== Packwood Lake lies at approximately above sea level and about 25 miles (40.5 km) southeast of Mount Rainier. Its main source of water is glacier-fed Upper and Lower Lake Creeks, which descend from Gilbert Peak (also known as Old Snowy Mountain). The lake is approximately 2 miles (3.2 km) long and 0.6 miles (1 km) wide. The lake is held in place by a natural dam. Approximately 1,200 years ago, Snyder Mountain, which borders the lake to the northwest, broke and slid down into the (then) Lake Creek valley, effectively plugging it and forming the lake. Maximum depth is approximately . The island in the lake is officially named Agnes Island, and also referred to by locals as both Wizard Island or Enchantment Island. The island is protected by the US Forest Service and no landings are permitted there.
