Takeout Retrace your path to the wooden bridge cross over the creek and take the first right - this is still Trough Creek drive. Follow this road just past the campground to the parking area near the dam and the "ice mine".
River Description In the first part of the run Trough Creek is hemmed in on one side at a time by limestone bluffs with scenic woodlands on the other side. The gradient is modest with periodic riffly rapids, and the occasional small drop cum surfing opportunity.
Shortly,(perhaps 100 yards)after the pipeline crossing there is an excellent surfing hole. This is best grabbed on the way downstream as getting back up and in once you've blown out is an arduous and paddle-banging task. There is a small eddy above it on river right for one boat to wait your turn. The river left side of this hole can be testy at higher flows.
The creek continues with periodic class II rapids and surfing opportunities until it briefly flattens as you pass through the developed portion of the park near the wooden bridge. Then the gradient, action, and multiple surfing opportunities return. There is a rapid, surfing spot and pool at Copperas Rock. Just below this the creek passes under a new bridge; within a hundred yards downstream of the bridge there is usually a nice glassy faced wave. A couple hundred yards below the glassy faced wave the creek departs from the road a little and makes a slight bend to the right where a limestone bluff rises nearly vertically from the left bank. At most levels (low to med-high) this is the most difficult rapid on the creek; at high levels is washes out.
Below this rapid you will pass under a suspension foot bridge and Abbot run enters from river left, cascading over Rainbow Falls. Just downstream from Rainbow Falls, high above you is Balanced Rock. There are a couple more fun drops, then you pass under another foot bridge and arrive at the pool backed up by the dam. Most boaters will usually take out above the dam. The hydraulic below the dam is lethal except for a side slot on far river left. If you run this remember to hold your paddle paralell to the long axis of your boat as you drop into the slot. One time one member of our group had his paddle bridge the opening and he did a fast and improptu limbo move, subsequently running the slot sans paddle. Keystone Canoeing by Ed Gertler is an excellent reference.
