There are 80 acres of lakes, 190 acres of wetlands, and six miles of intermittent streams on SMSC tribal fee and trust lands. Since 1999, the SMSC Land and Natural Resources Department has been conducting an on-going water quality sampling program to develop baseline surface water and ground water quality standards.
Two lakes, four streams, eight wetlands, and three ponds were sampled during 1999 – 2008 for total phosphorus, orthophosphate, total kjeldahl nitrogen, nitrate and nitrite, and chlorophyll a. Select water bodies, in close proximity to impervious road surfaces, were also sampled for metals. A Hydrolab™ multi parameter sensor was used concurrently to determine: dissolved oxygen, specific conductance, total dissolved solids, pH, and oxidation-reduction potential for all water bodies.
The following tables break down the pollution indicators associated with each water quality parameter.
| Parameter – Lab Verified | Indicator |
| Chlorophyll a | Measure of algal biomass |
| Total Phosphorus | Organic matter and fertilizers |
| Orthophosphorus | Organic matter and fertilizers |
| Nitrate + Nitrite | Organic matter and fertilizers |
| Total Kjeldahl Nitrogen | Organic matter and fertilizers |
| Ammonia | Organic matter and fertilizers |
| Total Suspended Solids | Sediment and silt |
| Calcium | Hardness |
| Magnesium | Hardness |
| Potassium | Deicer, salt – ion ratio |
| Sodium | Deicer, water softener, salt – ion ratio |
| Alkalinity | Acid buffering capacity |
| Chloride | Deicer, water softener, salt – ion ratio |
| Sulfate | Salt – ion ratio |
| Lead | Automobile contaminant |
| Copper | Automobile contaminant |
| Zinc | Automobile contaminant |
| Parameter-Hydrolab™ | Indicator |
| pH | Acid buffering capacity |
| Dissolved Oxygen | Aquatic life support |
| Redox | Reaction involving the transfer of oxygen |
| Specific Conductivity | Function of the total quantity of ionized materials |
| Total Dissolved Solids | Total solids remaining when evaporated to dryness |
