Long-Term Lake Trends
The Long-Term Lake Trends program provides a strategic and co-ordinated approach to monitoring water quality in lakes across B.C.
Lakes are complex ecosystems that are sensitive to a wide range of stressors that operate at provincial, regional, and local scales. Lakes are sentinels of environmental change, and long-term monitoring of water quality trends in B.C. Lakes allows for inter-annual variation to be distinguished from directional change. Understanding these trends can provide insights into the causes of change, and support effective watershed management.
- To determine current water quality status and long-term trends of the physical, chemical and biological properties of B.C. lakes.
- To assess lake water quality data in relation to ecosystem change, including watershed stressors and climate change.
- To evaluate lake water quality to Water Quality Guidelines and Objectives for key parameters, and determine lake trophic status.
- To provide accessible, accurate and timely water quality data for B.C. lakes to inform decision makers within government, industry, research institutions, and the public.
- To develop partnerships with stewardship groups and other programs such as B.C. Lake Stewardship Society, to provide a strategic and co-ordinated approach to provincial lake sampling.
