The lakes in SITES AquaNet and SITES Water

Seven lakes at seven different stations are central for SITES AquaNet and SITES Water. The monitoring for SITES Water, including lake and stream sampling, is carried out in six of the stations catchments and therefore covers a gradient in aquatic biogeochemistry e.g. nutrient concentrations, water color and catchment characteristics. SITES AquNet offers experimental manipulations in lakes with varying environmental conditions along a latitudinal gradient.

Stable stratification during winter, non-stable stratification during summer i.e. the lake mixes several times every summer.

Lake Erssjön develops stable summer stratification with anoxic bottom water. Its catchment is mainly covered with forest, with a minor share of peat and agricultural land underlined by granite bedrock.

The catchment area of 0.65 km2 is composed of 54% coniferous forest, 39.5% mire, and 6.4% water and is dominated by Svecofennian metasediments/metagraywacke bedrock covered by till and peat soils.

Lake Tarfalasjön is a glacial lake. Runoff from four tiny to small glaciers where the largest stopped calving in the lake in the 1950s. The catchment area is 8.6 km2, 15% is ice covered.
