The Kenya Defence Forces, the Kenya Red Cross and local volunteers were involved in the rescue operation.
The seven were rescued Monday afternoon after spending several hours on top of trees.
Makeshift rafts were used to ferry them to safety.
Mandera Deputy Governor Omar Maalim, county assembly Speaker Abdikadir Sheikh and Deputy County Commissioner Elvis Korir were also involved in coordinating the rescue mission.
“Our crops have been destroyed and we have also lost livestock,” said Mr Dakane.
According to villagers, 23 people had gone to work on their farms when it started raining on Saturday.
They said 16 villagers managed to leave the flooded area but the remaining seven could not do so and climbed trees to avoid being swept away.
“We are worried because a KCPE candidate is among those trapped on the farms and another man is unwell,” said a villager, Mr Mohamed Noor.
Area Ward Representative Abdinoor Dakane said officials had to seek help from the military because of the raging waters.
