Hunting this cache can be very dangerous. If you are not sure enough what you are doing, please do not attempt.
The coordinates are on top of the dam. The width of the top is a little less than 2 meters. If you are not careful enough, you will easily be fallen into the river which is more than 10 meters below. Proceed slowly to a point several meters to the "cut out". The cache is above you. The cache can be retrieved and returned very easily. You will love the placement mechanism.
