Kbal Spean is known for its carvings representing fertility and its waters which hold special significance to Hindus. Just {{convert|5 cm under the water's surface over 1000 small linga carvings are etched into the sandstone riverbed. The waters are regarded as holy, given that Jayavarman II chose to bathe in the river, and had the river diverted so that the stone bed could be carved. Carvings include a stone representation of the Hindu god Vishnu lying on his serpent Ananta, with his wife Lakshmi at his feet. A lotus flower protrudes from his navel bearing the god Brahma. The river then ends with a waterfall and a pool.
