Within the past fifteen years, eighteen artificial or man-made lakes have been constructed in Iowa to augment the fishing potentialities and general recreational facilities of the state. These little lakes range in size from twenty-five to some three-hundred surface acres. Most of them originally provided the citizenry with considerable fishing, but in recent years the anglers take in a few of them has fallen off sharply. Beeds Lake, a 130-acre impoundment in Franklin County, is a typical example. Constructed with federal assistance in the years 1934-1936, it was thought to be one of the outstanding lakes of its kind in the state. A limestone-masonry dam impounds a maximum of thirty feet of water, and nearly half of the area is shallow enough to support higher aquatic plants. Except for a limited number of limestone ridges, the bottom is covered with silt and sand loam. The source of water supply is surface drainage and a number of springs, and all of the immediate watershed is in pasture or park grounds. The entire land area is fenced to exclude livestock. A dyke, which previously formed the dam of an old mill pond, now divides the lake into two parts which will be referred to as the upper and lower sections.
