The location of the axis of the rock-fill dam is described as

follows:

Beginning at the Northeast corner of Section 9, T. 4 N., R. 73 w.,
6th Pri~cipal Meridian, Station 0 I 34.52 of the dam axis bears South 680 12'
West a distance of 4670~ feet. From station 0 134.52, the bearing of the
o
axis of the dam is North 26 43' W$st and the length of the axis is 245 feet.

At the right end of the dam a spillway is provided with s cepacity of 550

second feet. station 0 100 on the spillway line besrs South 680 52' West
