area under the curve. The results indicated that there were 11,672.6 acre-feet of 
water in Oakland Bay at low tide. By measuring the number of acres in the bay 
and calculating the average depth, a less reliable figure was obtained for the volume 
of the bay. It was 11,427 acre-feet and serves as a check on the first calculation. 
It was also found that 718 acre-feet of water remained in the deep hole above the 
Figure 50.— Locations of cross sections used in volume determinations 
“Narrows” in what is locally called “the head of the bay.” We have therefore an 
indicated volume of 12,390 acre-feet of water in the bay at low tide. (Table 15.)
