Area 39 has an area of about 10,500 sq mi and includes all or parts of 13 Kansas counties and 14 Missouri counties. Major streams draining the area are the Marais des Cygnes (Osage), South Grand, Little Osage, Blackwater, Blue, and Little Blue Rivers, which are tributaries of the Missouri River. Mean annual rainfall in Area 39 ranges from 34 inches in the west to > 40 inches in the east. Agriculture and forests are the predominant land uses. Streams, ponds, and reservoirs provide about 94% of the water used in the area. Groundwater supplies are limited except in the Missouri and Marais des Cygnes (Osage) River valleys where wells in unconsolidated deposits may yield from 100 to 2,000 gal/min, and in the southeast part of the area where wells in consolidated aquifers of Ordovician age yield up to 600 gal/min of good quality water. Strippable coal reserves are present in Pennsylvanian rocks throughout many parts of the area. Coal mining activity has increased sharply since the 1960's; this mining is subject to state and federal reclamation laws. Erosion, sedimentation, water quality degradation, decline in groundwater levels, and diversion of surface drainage are typical problems associated with surface coal mining.more » 98 refs., 24 figs., 3 tabs.« less
