Reservoir Water Quality Monitoring Data

The Ministry of Environment publishes water quality monitoring data for reservoirs, including general background water quality measurements and Carlson Trophic State Index (CTSI) values. Since the monitoring data are collected on-site each season and subsequently analyzed in the laboratory with quality control and assurance procedures, the data are usually made available one month after the end of each seasonal monitoring period.
