Mahāparinibbāna Sutta 4.23.5

4.23.5

Ayaṃ, bhante, kakudhā nadī avidūre acchodakā sātodakā sītodakā setodakā suppatitthā ramaṇīyā.

And again the second time the venerable Ânanda said to the Blessed One: 'But just now, Lord, about five hundred carts have gone over. That water stirred up by the wheels has become shallow and flows fouled and turbid. This river Kakutthâ, Lord, not far off, is clear and pleasant, cool and transparent, easy to get down into, and delightful. There the Blessed One may both drink the water, and cool his limbs.'
