with snow. In a northeastward band extending from
Cincinnati through Columbus, 6 inches of rain fell on
January 20-21; more than half of the state received at
least 3 inches of rain (Edelen et al., 1964).
Flood-control reservoirs in some basins reduced
peak flows of some streams and prevented flood dam-
age. The Licking River, which discharges into the
Muskingum River at Zanesville (see Figure 10.4),
exhibited higher flood levels in 1959 than during the
1913 flood, although 5 miles upstream from their con-
fluence the stage of the 1913 flood was 4.5 ft higher
than that of the 1959 flood.
A stream-gaging station lies on the bank of the
Licking River 3.65 miles upstream from its mouth
and at an elevation of 683.7 ft (Figure 10.5 map in the
back of the topic). The maximum stage of the 1959
flood at this gage was 32.46 ft, which means that the
elevation of the flood at this point was 716.2 ft. Any
structure in the immediate area of the gaging station
and lower than this elevation would have suffered
flood damage.
