The quantity of seepage water out of the reservoir is very important for some purposes. In some cases if it is large, we must terminate our plan. In this paper I have described the way of obtaining the coefficient of permeability and how to calculate the quantity of seepage water on an example test. The coefficient of permeability necessary to calculate the quantity of seepage water was obtained by the following: 1) Method of using a small pool, 2) Method of using an auger hole, 3) Method of using a vertical shaft and 4) Laboratory test. Results of the above three methods 1), 2), 3) are about the same and the method 3) seemed as the best. I calculated the quantity of seepage water by the following, 1) Method of approximating the actual field to an earth-dam. 2) Method of approximating the reservoir to a rectangular drain. In the method 1) the result was obtaind as we expected, but not in the method 2), because of its too much quantity of the seepage water to be expected.
