Salinity Because anions and cations carry electrical charges, water containing them can conduct electricity, and its ability to do so gives a measure of the total quantity of charged particles (ions) dissolved in it. This is known as the specific conductivity of water. Another measure of the total ion content of lake water is total dissolved solids (IDS). Specific conductivity (or conductivity) is measured with an instrument that passes an electrical current through a sample of the lake water between two platinum electrodes; units are micro-Siemens per centimetre (uS/cm).

The temperature regime in shallow lakes like Figure Eight Lake is quite different from that in deep lakes like Narrow Lake. The graphs on the left show the temperature (°C) from the top to the bottom of the lakes for a year (note the difference in the depth scale). The cross-sections show typical temperature patterns for each season. Water Quality form, a lake is said to be thermally stratified. During summer, the depth of the epilimnion increases, as a result of wind mixing and periods of cooler air temperatures.

They form by the accumulation of dead organic material such as sedge or moss peat. Solonetzic soils develop on saline parent material in imperfectly drained to moderately well-drained sites. They form under grassland vegetation, usually in association with Chernozemic soils. A drainage basin's soils affect a lake by influencing the rate of runoff and the amount and proportion of various nutrients and ions that move from the soils to the lake. However, little research has yet been done in Alberta to directly link the soil types present in the basin to the chemical composition of the receiving lake.
