The Mulchatna River has 5 full river blockages. The full blockage would require portages over or around. Boaters should fly the river before floating.

River Conditions Update

June 3, 2020: Conditions on the Chilikadrotna and Mulchatna Rivers have improved from 2019 but remain challenging.

The Chilikadrotna River one has one near blockage with a down tree across most of the main channel of the river. There are two woody areas. The first is just downriver from the Ptarmigan Creek confluence and the second is approximately the last three river miles before the confluence with the Mulchatna River. All woody sections are passable with a raft, but not easily done. A raft did just float the river. Regardless, smaller boats (e.g. kayaks, packrafts, etc.) may be easier because of their maneuverability. If the wrong river channel is taken in either one of those "woody" sections, it would be a challenge for any boat, and a portage is likely. For this we always recommended boaters overfly the river before floating.

Boater report update 9/9/20

"We found the Chili to be quite challenging with lots of log jams, couple sweepers blocking the channels and strainers everywhere. We portaged around at least 2 jams."

The Mulchatna River has five full river blockages and two locations of partial or near blockages. The near blockages are likely impassable for larger boats (rafts, catarafts, etc.) The full blockage would require portages over or around. Boaters should fly the river before floating.

These obstacles, on both the Chilikadrotna and the Mulchatna Rivers, are located outside of the park and preserve.
