The river in the CMR is full of boats and hunters, the whitetails are in both the river bottom and out in the dries. Big bucks are very hard to find until the rut and it is normally very cold that time of year. When I do it I either take a jet boat or drive and hike the ridges looking in to the willow flats. Long shots are a must. They raised the water level in the reservoir so lots of the flats are now under water.
Hope that helps, if you have any questions I will try to help.
