El & Bill - By circumstances related to my career as an educator, I possess some degree of knowledge of Big Horn Lake boating. I had begun teaching in 1960 in Hardin, the county seat of Big Horn County. Hardin is off the Crow Indian Reservation but for the most part surrounded by the reservation itself. In 1958 I floated (rafted) through the canyon, a long winding trip through many rapids. The Big Horn River then was a somewhat silt lalden river home to catfish and sauger, but several pristine trout streams flowing from canyons of the Big Horn Mountains and from the Dry Head flowed into it.
Big Horn Dam (first called Yellowtail Dam after a famous Crow tribal leader) broke ground in 1961 at the mouth of the Big Horn Canyon. Over 550 feet high, this concrete gravity arch dam spans the narrowest part of the canyon at its mouth close to Fort C.F. Smith, site of several Sioux Indian battles along the Bozeman Trail. (located 50 miles from present day Hardin)
A town named after the fort emerged to support the building of the dam, including an elementary school for 500 hundred students (K-8) belonging to construction related families. In 1966- 1969 I served as the principal of the school, and of course had a very close relationship with workers and officials. And I had a most unique boating (canoeing adventure) on Big Horn Lake because of that.
Once the dam was completed, it of course took some time for the lake to fill up. When the lake was about 3/4 filled, the Bureau of Reclamation
built a ramp and catwalk on the upstream side and slung in a few navy surplus steel boats to help secure floating debris from the lake itself. The dam was dedicated in 1968.
One Saturday I talked some of the dam workers to sling my seventeen foot Alumacraft canoe along with small Merc outboard over the dam face to the water below. One of the workers went along as crew, and we went up the lake to Black Canyon and up the canyon to where the stream was meeting the lake, reversed our route and turned up lake again and went to Big Bull Elk canyon and then returned back to the dam.
That was quite a trip and quite unofficial of course, and I believe my friend and I were probably the first recreational boaters on the lake. But during theat era things were a little more relaxed than today.
Once the dam filled up, the Big Horn river turned into a world class trout stream, with constant temperature water, which runs about a 100 miles to the Yellowstone River. The Big Horn never freezes during the winter.
Enough of that history.
Three (3) launch sites were created on the lake, one just above the dam, one where the Big Horn backs up into Wyoming, and the other called Barry's Landing just inside the Montana border The first and second sites have amenities. Barry's landing has a good launch site and parking for trailers and a beautiful camping area nearby. All sites are reached by all weaher highways.
I have made the run with both my old and newer Far West II. Since from top to bottom is a run of 80 miles, there is a variety of scenery, from sheer rock walls to timbered ridges . The upper launch site is subject to lake levels and best accessed in the early summer. There are few protected areas to drop anchor during the night. A C-Dory can handle any weather with ease.
Go on lne for more specifics on the launch sites.
Take care. John
