Description
Ice Harbor Dam is a mandatory portage due to the hydraulic structure blocking river passage, requiring boaters to completely exit the river and carry equipment around the dam. The portage involves navigating a concrete and rocky shoreline with potential for challenging terrain and significant elevation changes. Paddlers must exercise extreme caution and plan carefully for this section, ensuring safe boat and gear transport around the hydroelectric infrastructure.
