Abstract

Observations upon bogs in the vicinity of the Okoboji Lakes in Northern Iowa were made in summers of 1936-37-38. The area was about thirty-five by twenty-five miles. The locations of these hogs are for the most part on the east or north slope of glacial hills in the Wisconsin and Iowan drift sheets. In general these bogs are rounded elevations a foot to twenty feet in height. Water issues from the apex of a mound and flows down over the surfaces forming small pools. The flow is independent of local rainfall. The temperature is uniform in all bogs studied although they were miles apart. The temperature was 8½ to 9½ degrees Centigrade. There is a general agreement in the chemical content of the bog waters and in the pH measurement. This is true only of the issuing waters. As the water moves clown the slope it changes rapidly in temperature and content. Considerable variation was observed in pools situated a few feet from each other. These changes were sharply reflected in plant and animal life.
