While the mean annual runoff is relatively high (435 million m3/a), the means to harness this resource through the construction of dams is limited by various factors. Small dams on the main stem of the river are not viable due to the high sediment load, while larger dams which could serve the whole region, while technically feasible, would be very expensive due to the unfavourable geology.
