This report examines the distribution and availability of water quality reports in the state of Oklahoma. Based on legislation from the Clean Water Act and regulations from the Environmental Protection Agency's "Public Participation Handbook for Water Quality Management," depository libraries must be established to provide citizen access to various water quality reports. Results from a survey questionnaire investigating the effectiveness of the depositories in Oklahoma suggest that the depository system has been ineffective in accomplishing its mandated responsibilities. Appendices include a list of agencies and depository libraries, tabulated responses of the survey of depository libraries receiving water quality materials from the three agencies designated by the governor of Oklahoma, and sources for additional information.
