I found this one a couple of weeks ago protecting its territory which consisted of an area on a large pond located near the border of Wasatch County and Utah County a few mile up Utah Canyon. I'm not sure the pond even has a name.
It is pretty much an extension of the Provo River and can be reached by crossing the bridge at Wildwood. But be careful, The famous Heber Creeper (train) is often chugging along the tracks (q.v.). You don't want to be on the bridge when it is passing. Jon and I had a close call.
