Johnson on October 2, 1965 (1). This Act required all states to prepare water quality standards for interstate streams within their boundaries, and after holding public hearings, adopt such standards before June 30, 1967 (2-1). After holding the required public hearings, the South Dakota Com mittee on Water Pollution adopted, on February 16, 1967, Water Quality Standards for the Surface Waters of South Dakota (2-ii). These standards were sent to the Federal Water Pollutioh Control Adminis- tration (FWPCA) for review and approval. FWPCA reviewed these stan dards and suggested some modifications. On August 4, 1967, the State Committee sent to FWPCA a letter of concurrence with respect to the changes in the standards. This letter was attached to the original water quality standards as an addendum. On August 7, 1967, the Sec retary of the Interior, Stewart Udall, informed Governor Nils Boe that the South Dakota Water Quality Standards were officially approved. The pending adoption of these water quality standards, in par ticular the proposed standards· for the Big Sioux River below Sioux Falls, served as the prime factor for initiating a project to determine the impact of imposing water quality standards on this reach of the 2 river. The project was composed of four phases. The first two phases have been completed, this study reports on the third phase, and the · fourth phase is �n progress . The first phase of the project compared the past water quality of the Big Sioux River downstream from Sioux Falls, South Dakota, with the quality requirements prescribed in the water quality standards . This phase was conducted by John M. Herried (3). He showed that the Big Sioux River at Brandon had met the originally proposed state water quality standards except for the coliform limits . He emphasized that the major reason that these standards were met was because the city of Sioux Falls provided excellent wastewater treatment. Herried also showed that the Big Sioux River below Sioux Falls would be in the intermittent stream use category for a significant por- tion of the time. The river is placed into this category when the daily average wastewater flow or the daily average return flow from irrigation comprises fifty percent or more of the flow in the river . He further showed that because of the projected increase in wastewater flow for the city of Sioux Falls, the frequency of occurrence of the Big Sioux River entering the intermittent stream use category would increase in the future unless additional dilution water could be pro- vided (3-23) . Herried's analysis was ·completed before the addendum was appended to the state standard�. The addendum, in effect, proposed a change 3 in the minimum dissolved oxygen requirement for this reach of the river from 2. 0 to 4. 0 milligrams per liter (mg/1). Thus, Herried's con clusions with respect to the Big Sioux River below Sioux Falls meeting the dissolved oxygen parameter may have been premature. The effect of the proposed change in standards was discussed by Daniel J. Naughton in the second phase of the project (4). He showed that the dissolved oxygen concentration in the Big Sioux River down stream from Sioux Falls was frequently less than 4. 0 mg/1. Thus, this reach of the river did not meet the minimum acceptable dissolved oxygen concentration that the FWPCA requested, and during these times it would be in violation of the proposed water quality standards. Naughton also sought to determine the relationship between dis solved oxygen (00) and various river conditions . Using the statistical technique of multiple linear regression,. he derived a mathematical ex pression equating the minimum dissolved oxygen in the Big Sioux River below Sioux Falls with its flow, temperature, and biochemical oxygen demand (BOD). With the equation it was possible to estimate, for a given BOD and temperature, the flow required to maintain a minimum DO concentration of 4.
