Almost certainly too low for whitewater. We need your input to fine-tune ranges and ratings! Add comment or report regarding your perceptions of various flows! Gauge (drainage area 14.9 sq.mi.) is well down on this section, thus will accurately portray actual flows.


River Description

The Gratiot River (I'm told the locals pronounce it "grashit") is a tiny stream that may be an option if the Eagle is too high.

There are two sections of elevated gradient, the first being to either side of the Cliff Rd bridge and the second through the Upper and Lower Falls sequences. There is about five miles of flat, and at times marshy, river between the steeper sections.

The lower "Falls" section could be done as a shorter run (from Five Mile Point Rd bridge yields a run of about 3.5 miles). Upper Falls is a fairly long, low angle slide. Lower Falls is shorter and is of mixed bedrock/boulderbed composition, also more of a rapid than a true falls.

The road to the take-out is a logging track that may not be driveable in the early spring. Four-wheel drive and high clearance recommended. As with all small U.P. rivers, this is prone to strainers.

Rapid Descriptions

Drainage area ~6.8 square miles. (Class N/A)

By my best estimation, using online planimeter and topo maps, drainage at our listed put-in is ~6.8 square miles. By the gauge (well down the run) it has more than doubled, to 14.9 square miles.
