In 2013 the lake will be stocked with larger catchable sized rainbow trout as well as jumbo trout (1-1.5 lbs each).
Anglers can expect excellent angling opportunities throughout the late spring and summer season.
This high lake (2788 feet) 3½ miles northwest of Salmon-La-Sac is accessible by a Forest Service road from the upper Cle Elum River. Cooper Lake enjoys a year-round open fishing season and in the past has provided fair fishing for brook trout and rainbows 8-10 inches. Brown trout in the 1 to 3-pound range and some much larger are also available. Small kokanee and cutthroat are also taken. Closed to fishing for bull trout. Please carefully release any bull trout that are inadvertantly hooked.
A boat launch is available, but all motors are prohibited by county ordinance. There is a small US Forest Service campground at the lake.
