Water snakes are usually deadly and it's unlikely you can get help quickly enough after being bitten, so avoiding them is your only line of safety. If you know water snakes are in a body of water, the safest thing is to stay out of the water. There are plenty of safe places to go swimming in the world, so choose those places for your next trip. Even if the water is usually safe, the heavy rains may have caused snakes that are usually land-lubbers to get caught up in the water and they'll be attempting to get back to safety.
