SOLUTION: Three optical fibers, comprising an optical fiber for incidence and first and second optical fibers for reflection, are connected to a water pressure detector incorporating a displacement member comprising a diaphragm or bellows displaced by water pressure. The ends of these three optical fibers are disposed opposite to a displacement surface of the displacement member with a vacant space between. The optical fiber for incidence and the first optical fiber are inclinedly disposed so that their axes cross each other in the displacement surface of the displacement member while the second optical fiber is disposed at a position more distant from the optical fiber for incidence than the first optical fiber. A f1irst reflected light intensity sensor and a second reflected light sensor are attached to the other ends of the first and second optical fibers, respectively, while an operation means is connected to the first and second reflected light sensors. A light intensity ratio between first and second reflected light intensities is operated by the operation means to find water pressure from a previously obtained correlation between a light intensity ratio and water pressure, and a water level is found from the found water pressure.
