L. G. Toler (compiler) 1982 The increased demand for water and concern for the quality of the water resources of Illinois have lead to increased demand for water-resources data. Representatives of the major water-data-collecting and water-data-using agencies met in Peoria, Illinois, on February 23-24, 1982, to (1) exchange information on current water-data programs and needs; (2) identify areas where data are needed; and (3) foster coordination and cooperation between agencies. Recommendations of the group included (1) annual meetings of agencies for coordination of activities; (2) standard methods for collecting and analyzing water data be adopted; (3) a centralized data system be established as a means of sharing water data; (4) water data should be indexed and cataloged, either by each agency or by some centralized system; (5) a statewide water-data-coordination committee should be formed with members from all water-related agencies; (6) a work group be formed to consider the use of uniform water-data codes; and (7) a cooperative working agreement be developed among all water-data-collection agnecies in the State to coordinate and maximize efforts on basin-intensive projects. application/pdf 10.3133/ofr821001 en U.S. Geological Survey, Proceedings, Illinois water-data-users meeting reports
