Copper River (Iliamna Lake) Professional Review and Guide
"From its headwaters above Meadow Lake, the Copper River begins as a series of lakes (Meadow Lake, Upper Copper Lake, Lower Copper Lake) and flows westerly for 32 miles into Intricate Bay on Iliamna Lake. (This Copper River is not to be confused with the glacier-fed Copper River, described elsewhere in this guide, which flows into the Gulf of Alaska.) Traversing spruce and cottonwood forests, the run from Upper Copper Lake begins with 2 miles of Class III to IV whitewater. Then you paddle across Lower Copper Lake to the outlet, which features 3 miles of Class III whitewater. The water moves swiftly over a boulder-strewn bottom to two waterfalls.
The first waterfall drops 15 feet, the second drops 32 feet. Approaching the falls, watch for a tall cutbank on the right, half a mile above the first falls. Just upriver from the falls is a tall cutbank on the left. Take out on the left side of the river before reaching this cutbank and follow a portage trail half a mile to a point below the two falls. From this point, 6 miles of Class II and occasional Class III water leads to 6 miles of Class I to Intricate Bay. Approach sharp bends in the river with caution; they often include whitewater."
