farm and woods scenery to an iron bridge, where kayak and canoe slalom races are held. Below the bridge the river becomes Class 3-4, with a short gorge with several abrupt drops. The biggest of these is about four feet at Decoration Rock. Below, the river continues fast and technical with many rocks and constant maneuvering required. The river is continuously rapid, leading through larger drops at Battering Ram rapid and Corkscrew. Eventually the river flattens to Class 2 until a final, ledge rapid at Bear's Den, just above the reservoir. The Upper Farmington is barely runnable (very scratchy with many exposed rocks and pinning possibilities) during fall dam releases, and is a much better run at levels of about 600 cubic feet per second (16,990 L/s), or about 5 feet (1.5 m) on the internet gauge for that section. A second whitewater section is found in Tariffville, Connecticut, one mile (1.6 km) of technical Class 3 water which is runnable all year round. The river is normally paddled at levels between 1.5 and 2.75 feet (45–75 cm) on the internet gauge; above 2.5 feet (75 cm) it becomes significantly heavier and more dangerous. This section includes the famous T-ville Hole, where kayakers can practice hole surfing and freestyle moves above a flat pool. Below the Hole is a broken dam, where the river funnels through an abrupt four foot drop into a large wave. This area is popular with swimmers in summer, and it is risky due to heavy currents and undercut rocks. There have been at least three fatal drownings in the Tariffville Gorge section, primarily people who were not properly prepared or trained for the heavy rapids and pinning obstacles in the gorge. Paddlers without helmets, lifejackets and Class 3 whitewater skills should end downriver trips at Tariffville Park, just above the start of the gorge. Other whitewater areas include Satan's Kingdom in New Hartford, Connecticut, which is popular with tubers, and the Crystal Rapids section in Collinsville and Unionville, Connecticut, which is about four miles (6 km) of Class 1-3 training waters with a bicycle and pedestrian path on the right side of the river. Entrance to the park is free. A service will also pick tubers up and drop them off at certain points.
