Opopeo is a small spring, feeding a stream that empties out into Lago Zirahuen. It is the habitat of the very rare Allotoca meeki.
Once home to many species, the pool at the spring has only introduced species now – mainly black bass from North America. Some of the native species survive, but only in the little streams leading from the pool.
