The purpose of the study id to demonstrate and evaluate the effectiveness of geographical information system inputs to water quality improvement programs. The particular program in this case is the federally sponsored Model Implementation Program (MIP). The water quality problems addressed in the study stem from non-point sources of pollution. The major non-point source pollution is soil erosion from agricultural land. It must be noted that the purpose of the study is not to evaluate the effectiveness of water quality improvement programs. That evaluation is the goal of MIP and beyond the scope of this stud. The information needs for a quality improvement program are usually very complex. Management decisions addressing water quality problem associated with non-point source pollution require the integration of land cover, soil, and land management information. The use if the complex information consumes time and manpower that could be utilized more efficiently to implement the management program. It is anticipated that the use of a computerized geographic system will enable more efficient use of time and resources.
