All of the above-mentioned works have been constructed, except 800 feet of the main breakwater, and the shore arm, and 220 feet of the sand catch.
Page 26 - They stand opposite the greatest width of the lake and exposed to the greatest force of the heavy storms from the north. The effect of the waves upon them is not only seen in their irregular shape, but the sand derived from their disintegration is swept down the coast below and raised by the winds into long lines of sandy cliffs.
