ft.
To find how many more feet the river needs to rise to be at the major flood stage of 13 ft, we need to add up the measurements of the additional rise in the river:
1 1/12 + 1 5/12 = 2 6/12 = 2 1/2 ft.
Therefore, the river needs to rise an additional 2 1/2 ft to reach the major flood stage of 13 ft.
