The Dorset Environmental Science Centre generates a diverse array of environmental data designed to characterize the state of Ontario's aquatic ecosystems and investigate the effects that multiple stressors have in affecting their health. We have monitored lakes and streams, many for more than 40 years, across 7 major initiatives:

  1. An intensively-sampled group of nine watersheds with ~ 40 years of data on chemistry, physics and biology in both the lake and their catchment streams (Dorset A-lakes).
  2. An integrated set of sampling sites monitoring fluxes of water and solutes from 20 upland catchments and 6 lakes small enough to study inputs, outputs, and apply mass-balance and modeling approaches (Dorset Streams).
  3. A regularly sampled (spring/fall) group of ~ 30 lakes that increases the spatial extent of our physical, chemical and biological, monitoring program for over 20 years (Dorset B-lakes).
  4. Benthic macroinvertebrates and associated environmental variables are collected on ~20 lakes and ~15 streams in the Dorset area once per year for ~20 years(stream benthos=spring / lake crayfish=summer / lake benthos=fall).
  5. Spatial surveys (typically once per several years) that contribute to larger regional datasets on lake and stream ecosystems, including fish community data from the A-lakes.
  6. Most recently, we have also been collecting real-time high frequency temperature, oxygen and meteorology data from an automated raft (THELMA) on Harp Lake.
  7. The Lake Partner Program and the Ontario Benthic Biomonitoring Network which generate citizen-science based water quality and benthos data (respectively) on hundreds of lakes and streams in Ontario.
