This investigation was aimed at evaluating the quality of water and characteristics of sediments leaving three nearly level watersheds in the Lake Plain sector of the Maumee River Basin during a 32-month period as a function of soils comprising the watersheds. Each watershed consisted of a soil of major extent (Paulding, Hoytville, or Millgrove) developed from the three most extensive geologic deposits present in the basin: lacustrine, glacial till, and beach sand, respectively. The results indicated that water quality is a function of soil characteristics, discharge, and year. The finetextured Paulding watershed yielded lower concentrations of calcium, magnesium, and bicarbonate ions than the other two watersheds, but higher concentrations of sodium, potassium, and phosphorus. High concentrations of the latter three elements were attributed to the presence of septic tank effluent in the drainage ditch sampled. The Paulding watershed also yielded the highest concentration of sediment, which implies that nearly level watersheds of the basin, particularly fine-textured watersheds, may represent significant contributors of sediment entering the Maumee River. Flocculation of clay minerals in the sediments during fluvial transport resulted in increasing particle size and changing mineralogy on moving downstream from headwater areas.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
