The Khlong Tha Dan Dam was completed in 2005. It is 93m high, 2720m long and an incredible 5.5 million cubic meters of concrete. It has a storage capacity of 224 million cubic meters of water. It is the biggest dam in Thailand. It is also the largest and longest roller compacted concrete (RCC) dam in the world. The lives of Nakhon Nayok's people have already improved with the completion of the dam. Tourism and agriculture revenues are up and local land values have jumped sharply as investors look to cash in on the booming tourist industry. Dams are rarely architecturally beautiful but the sheer scale of these constructions makes them an impressive sight. Visitors can go to the top of the dam and enjoy the spectacular scenery. There is a small park by the top and from there you can walk a few hundred meters along the top of the dam. You can take a tour bus trip along the top of the dam to fully appreciate the fine views and the scale of the construction. The 15-minute trip costs 20-baht. There are great views either way. In front of the dam, you have a view along the river and across Nakhon Nayok province. Behind the dam is the reservoir. It is possible to take a boat trip a few kilometers along the reservoir to the stream that feeds it.
