He described the situation as terrible, saying the roads have remained impassable.
He noted that about 40 per cent of the farmlands in Maiduguri had been submerged ahead of harvest season.
Mr Shettima said this on Wednesday when he received the speaker of the House of Representatives, Tajudeen Abbas, at the Presidential Villa, Abuja.
Residents of Maiduguri town displaced by water from the Alau Dam are beginning to return to their homes as flood water recedes gradually.
Mr Umar attributed the flooding to the overflow and collapse of the Alau Dam in Konduga LGA.
President Bola Tinubu had directed Mr Shettima to immediately visit Maiduguri to assess the devastating flood in the state capital.
Some of the areas affected by the incident included Shehuri, parts of the Government Residential Area, Gambomi, Budum, Bulabulin, Adamkolo, Millionaires Quarters, Monday Market and Gwange.
The last time the dam had such a problem was in 1994, resulting in unprecedented flooding in Maiduguri when almost half of the town was flooded.
“We are in distress and afraid that more rainfall or release of excess water from the dam can spell more doom for us,” said a resident.
Several wards in Maiduguri were flooded when part of the dam collapsed in 1994 due to excess water from the dam.
