Igbo history.Natural Area. 6. February 2021 / Umu Udo Integration, / Leave a comment How many of you know about Oguta lake (green) and Orashi river (brown). The two waters have a boundary in Imo state. The fish in Oguta cannot enter Urashi and vice versa. It was reported that if you put the two waters in a bowl with their fish(s), the waters will simply separate themselves and the fishes also to their waters. It was also said that when the two waters are put in one bottle and shaken, the bottle might burst. (proven) One of the nature’s wonders.~Copied.
