South Dakota Criteria Development Progress
This page provides information about the progress South Dakota has made towards the development of numeric criteria and shows what statewide and site-specific criteria are currently in effect.
Note: The information on the tabs below reflects the information available on EPA’s
Water Quality Standards Repository. The criteria presented here will be updated as new water quality standards documents are posted to the Repository.
Numeric Criteria Development
The information presented below gives a summary of state progress towards the development of numeric criteria. The information comes from EPA’s “State Adoption of Numeric Nutrient Standards (1998-2008)” report, current water quality standards, program activity measures, and nutrient criteria development plans. Links to the South Dakota’s Nutrient Criteria Plan and state water quality standards are also provided.
Existing Numeric Criteria
| Waterbody Type | N | P | Chl-a | Clarity |
|---|---|---|---|---|
| Lakes and Reservoirs | ||||
| Rivers and Streams | ||||
| Estuaries | N ⁄ A | N ⁄ A | N ⁄ A | N ⁄ A |
| Wetlands |
S = Statewide W = For selected waterbody N ⁄ A=Not Applicable
Note: See Statewide Criteria and Site-specific Criteria tabs for more information.

Statewide Criteria
The information on this tab shows EPA-approved nutrient criteria for South Dakota’s waterbodies. The language presented below comes directly from state water quality standards and applies to all waterbodies within the state (unless a waterbody type or designated use is noted). Criteria applicable to specific waterbodies within the state can be found on the “Site-specific Criteria” tab. For more information, refer to the South Dakota water quality standards.
The following information reflects South Dakota’s water quality standards posted to the Water Quality Standards Repository as of November 2010 (EPA-approved January 1999).
74:51:01:06. Visible pollutants prohibited. Raw or treated sewage, garbage, rubble, unpermitted fill materials, municipal wastes, industrial wastes, or agricultural wastes which produce floating solids, scum, oil slicks, material discoloration, visible gassing, sludge deposits, sediments, slimes, algal blooms, fungus growths, or other offensive effects may not be discharged or caused to be discharged into surface waters of the state.
74:51:01:08. Taste- and odor-producing materials. Materials which will impart undesirable tastes or undesirable odors to the receiving water may not be discharged or caused to be discharged into surface waters of the state in concentrations that impair a beneficial use.
74:51:01:09. Nuisance aquatic life. Materials which produce nuisance aquatic life may not be discharged or caused to be discharged into surface waters of the state in concentrations that impair a beneficial use or create a human health problem.
74:51:01:12. Biological integrity of waters.
All waters of the state must be free from substances, whether attributable to human-induced point source discharges or nonpoint source activities, in concentrations or combinations which will adversely impact the structure and function of indigenous or intentionally introduced aquatic communities.
74:51:01:44. Criteria for domestic water supply waters.
The criteria of parameters for domestic water supply waters and their allowable variations that are not included under § 74:51:01:55 and Appendix B, unless set under § 74:51:01:24, are as found in the following table:
| Parameter | Criteria | Unit of Measure | Special Conditions |
|---|---|---|---|
| Nitrates as N | ≤ 10 | mg/L |
Site-specific Criteria
The information on this tab shows EPA-approved site-specific nutrient criteria for South Dakota’s waterbodies. Criteria on this page apply only to the waterbodies listed below. Criteria applicable to all waterbodies within the state are found on the “Statewide Criteria” tab. For more information, refer to the South Dakota water quality standards.
The following information reflects South Dakota’s water quality standards posted to the Water Quality Standards Repository as of November 2010 (EPA-approved January 1999).
