Grand Ethiopian Renaissance Dam govern the impacts during the reservoir filling phase include the initial reservoir elevation of the Aswan High Dam, the rainfall that occurs during the filling period and the negotiated arrangement between the three countries. These studies also show that only through close and continuous coordination, the risks of negative impacts can be minimized or eliminated. The reservoir volume (74 billion cubic meters) is about 1.5 times the average annual flow (49 billion cubic meters) of the Blue Nile at the Sudanese-Egyptian border. This loss to downstream countries could be spread over several years if the countries reach an agreement. Depending
