Approximate - nearest available gauge. Use as general reference only.
A tiny side stream (outflow from Knute Lake and two other unnamed lakes (on all maps I find online)) enters from river-right. At times of high flow, it may be worth a side-hike, as it has considerable gradient (dropping at least 50' in only 1/3rd of a mile). Mostly, however, this looks too small and much too tree-encroached to paddle.
On the Echo, low-grade rapids continue for about a quarter-mile. This is a well-forested area, and it appears deadfall is likely to be a strong possibility. Be alert, and ready to catch an eddy to exit river if/where necessary to portage.
