Impairments
Alkalinity -		Alkalinity is a measure of the buffering capacity of water, or the capacity of water to resist change in pH.
Cd -		Cadmium, a metal that in high enough quantities can cause stress and/or be fatal to aquatic life.
Chlorides -		Chloride can be toxic to aquatic organisms and can affect the taste of food products.
Chlorophyll-a -		Chlorophyll-a is a major pigment in algae that may be used to estimate the biomass of algae found in water.
Cond -		Conductivity, a measure of the waters ability to conduct a current. It is used as a measure if the dissolved ionic matter in the water.
Cu -		Copper, a metal that in high enough quantities can cause stress and/or be fatal to aquatic life.
DO -		Dissolved Oxygen, Results from the photosynthetic and respiratory activities of the biota in the waterbody. DO is essential for aquatic life.
E. Coli -		Escherichia coli (E. coli), is an indicator of waste from warm-blooded animals. Fecal coliform may also indicate the potential for pathogens in the water supply.
FCA -		Fish Consumption Advisory.
Fecal -		Fecal Coliform, is an indicator of waste from warm-blooded animals. Fecal coliform may also indicate the potential for pathogens in the water supply.
Fish Kill -		A waterbody that has had a reported fish kill.
Nitrate -		Inorganic form of oxidized nitrogen resulting from bacterial oxidation of ammonia.
Nutrients -		Nutrients are ultimately responsible for the eutrophication or productivity of a waterbody. Typical nutrients measured are total nitrogen and total phosphorus.
pH -		Acidity/Alkalinity the measure of the hydrogen ion concentration. pH can effect many chemical reactions in water.
Salinity/SAR -		Salinity/Sodium Absorption Ratio, high concentration of sodium can render in the soil hard and resistant to water penetration and also limit the uptake of water by plant roots.
Sed -		Sediment, typically refers to excessive sediment that caused the reduction of depth in a lake or reservoir.
Selenium -		Selenium is an essential trace element for animal nutrition. It can also be toxic to plants, animals and humans at higher concentrations.
Sulfates		Sulfur is an important plant nutrient. Sulfates can cause gastrointestinal problems to humans at high enough concentrations.
TDS -		Total Dissolved Solids, material that can pass through a filter and is typically Total Dissolved Solids, Is a measure of salts in water, and can be composed of earth compounds, particularly bicarbonates, carbonates, sulfates and chloride.
Temp -		Temperature, Water temperature is important for aquatic life and chemical processes in water.
Total Ammonia -		Total ammonia, in high concentrations, is toxic to aquatic organisms, including invertebrates and fish.
TSI -		Carlson's (1977) Trophic State Indices, Carlson’s TSI is a measure of productivity in a lake or reservoir. Typically Secchi depth, chlorophyll a, and phosphorus measurements are used to calculate a mean TSI value.
TSS -		Total Suspended Solids, the organic and inorganic material left on a standard glass fiber filter (0.45 micron) after a water sample is filtered through it. TSS can be used to measure the volume of solids in a waterbody. Too much suspended solids can be harmful to the biota in a stream.
Zinc -		Zinc, in high enough concentrations, can be toxic to aquatic organisms.

TMDL Project Status
	Assessment Initiated -	Data for developing the TMDL is being collected.
	Delist -	A waterbody has been removed from the TMDL list. Delisting may occur when a TMDL is approved by EPA, water quality standards are met, a waterbody was listed in error, additional state effluent controls address water quality problems, reservoirs have been breached and are no longer a viable waterbody, or data assessment methodologies have been modified.
	Delist* -	Water quality standards have been met; however, a TMDL was completed because an assessment had already been initiated while the segment was previously listed.
	Not Initiated -	Projects are proposed and waiting final funding to begin assessment.
	Special Approvals -	A waterbody that had sufficient data to write a TMDL before the first 303(d) list was published.
	TMDL in Public Notice -	During the public notice phase, a TMDL has been developed and is ready for public review and comment. Comments can be sent to denrinternet@state.sd.us. Comments received are reviewed and considered before submitting a final TMDL to EPA for approval.
	TMDL Public Noticed -	The public notice comment period has passed. Comments received are being reviewed and considered before submitting a final TMDL to EPA for approval.
	TMDL Approved -	EPA has approved a TMDL as submitted by the state.
	TMDL Not Required -	Waterbody is meeting its beneficial uses.
	TMDL Withdrawn -	The formal withdrawal of a TMDL because of, but not limited to, new water quality data, revisions in water quality standards, or changes in assessment or Integrated Report listing methodologies.
