The Nigeria Hydrological Services Agency (NIHSA) wishes to inform the general public, especially those living by the Banks of River Niger and its floodplains, that River flooding is likely to occur. The middle Niger portion of the Niger Basin (Niger Republic) experienced high flows last week. The flood has advanced into the Lower Niger (Nigeria). Accordingly, both Kainji and Jebba Dams are already spilling water downstream. The Level of water in Lokoja as at today, 29th August, 2018 (downstream the confluence), is 8.69 meters . This value has exceeded the corresponding value of 8.57 meters that occurred on 29th August 2012. Meanwhile, the flooding that occurred in Kaduna on 23rd and 24th August 2018, has started arriving Shiroro Dam built on River Kaduna. In the event that Shiroro Dam equally starts spilling water, that will portend more danger downstream. The following states should be on watch out; Kebbi, Niger, Kwara, Kogi, Anambra, Delta and Bayelsa. Inflow contribution from River Benue is equally advancing. Meanwhile, the Lagdo Dam in Cameroon is still impounding water, so no spilling yet into River Benue.
