Dolan Falls, supposedly the biggest continuously-flowing waterfall in Texas, is a 12-footer that is known to be runnable (by experienced whitewater boaters with appropriate boats and gear) at 2.3' and higher. The lead-in is likely too shallow at lower levels than that. At very high levels, Texas Whitewater describes "nasty hydraulics." Suggested portage for long boats and recreational boats at all levels.
If you choose to run the falls in your whitewater boat, it is strongly recommended that you unload it first. The basic move is to enter from river left into the left-to-right chute above the falls, then take a right boof stroke at the lip of the falls to send you left and away from the hydraulic at the base. At higher water, it is likely that another line opens up to the right, avoiding the meat of the falls. Use extreme caution, however, as there is also a "room of doom" at the right, which may come into play at high water.
Dolan Falls is owned by the Nature Conservancy, and there is a 24-hour surveillance camera located on the river right bank. In general, the rangers will advise you that running the falls is OK, provided that you have sufficient skill and proper equipment, but hanging out on the banks for any significant length of time is not OK. The rangers seem to believe (incorrectly), and have recounted to boaters, that the only reason why it is legal to portage Dolan Falls is that the state has a cooperative agreement with the Nature Conservancy.
