Temperature

Is Woods Lake Stratified? Thermally? Chemically? Woods Lake is thermally stratified because the with an increase in depth, the temperature decreased. Woods Lake is chemically stratified because of the increased level of pH, chloride, sodium, phosphate that occur below 8 meters.

pH

Dissolved Chloride

Conductivity

Dissolved Phosphate

Does Woods Lake have high nutrient levels? Woods Lake has high nutrient levels (phosphate) at 8 meters below the surface and deeper. This is possibly caused by the algae decomposing at the bottom of the lake.

Dissolved Sodium

Is there evidence of road salt input at Woods Lake? The Na and Cl increases at 8 meters and below. Salt water is more dense than fresh water.

How might the water chemistry affect the lake ecosystem? There is not as much dissolved oxygen in the water. Fresh water species that are sensitive to salt water will be affected. There is no dimictic turnover in the lake.

Have humans impacted the water chemistry at Woods Lake? If so, how? Humans have impacted the water because of the increased level of sodium, phosphate, chloride and pH. Storm sewers overflowing, road salt, lawn fertilizers and clippings. Overflow from the retention ponds and increased level of rainfall also influences this.
