THANKS TO Harleyharry 8 FOR REPLACING THE CONTAINER!
The new Khlong Katha Dam, also known as the Chalong Dam, was recently constructed to ease water supply shortages to the people in Chalong, Rawai, Kata and Karon, and as supplemental water holding for the nearby Bang Wad Dam.
The reservoir that was created by the new dam has erased some local roads, which, as of the time of this posting, still exist on Google Maps. These "Ghost Roads" can cause some confusion when navigating the area, but the new roads are clearly marked and driving is very safe.
The reservoir is actually somewhat scenic, and a popular place for cycling and jogging, as traffic is quite light.
It is also located very near to the beautiful Srisupharam Temple, with it's enormous, white Stupa, which is definitely worth a visit, all by itself.
This cache should be an easy park and grab, along the winding perimiter road around the lake.
