The pilot was positioning the float-equipped airplane in support of hunting clients. He circled a lagoon to assess the wind and water conditions. After landing, as the airplane was slowing off the step, the floats struck a submerged sand bar. The airplane nosed over but remained floating upside down. The pilot reported that overcast skies and the color of the lagoon bottom prevented him from seeing the sandbar.
