It might be iffy now. My experience is that it can vary from year to year. I've accessed the river when it was about 8-9 feet (in a rather small boat) and got stuck hard one time when it was about 10. If you're going from the lake to the river be very careful when you arrive at the river rock jetty, particularly if the current is strong (which it probably is now). You have to make a sharp turn to the left and can find yourself stuck on a mud bar before you know it.
