Environment Canada and the provincial Department of Environment and Conservation have been monitoring ambient surface water quality of selected water bodies in the province since 1986 under the Canada-Newfoundland Water Quality Monitoring Agreement (WQMA). The purpose of this Agreement was practical coordination and integration of federal and provincial water quality monitoring activities. On April 29, 1986, an Agreement was signed between the federal and provincial government to establish a joint water quality monitoring network. The WQMA provides for the regular monitoring of an index network of stations, as well as an annual recurrent study concentrating on water quality, sediment and biota in a selected watershed. Since its inception, the Agreement has seen water quality data collected at a total of 111 monitoring sites.

A shapefile of the Nova Scotia Automated Surface Water Quality Monitoring Network monitoring stations. The network was established in 2002 to assess near real-time water quality in surface waters across the province at five river stations and one lake station. The results are used to help manage water resources, determine baseline water quality in lakes and watercourses throughout the province, evaluate the impact of human activities on surface water, and assess long term trends in water quality.

The Fish Habitat Management System for Yukon Placer Mining replaced the Yukon Place Authorization (YPA) in 15 Yukon watersheds on April 11, 2008. Founded on principles of adaptive management and incorporating a risk-based approach to decision-making, the system is intended to balance the objectives of a sustainable Yukon placer mining industry with the conservation and protection of fish and fish habitat supporting fisheries Adaptive management recognizes that the effectiveness of any management system is hampered by a degree of uncertainty and lack of knowledge. It seeks to improve the system by monitoring the effects of management actions, in order to learn from the results. The Adaptive Management Framework for Yukon placer mining is complemented by traditional knowledge and water quality objectives monitoring, aquatic health monitoring and economic health monitoring programs. The results should provide new information and a rational basis for making any adjustments required to achieve the two management objectives. The water quality objectives monitoring program is governed by the Water Quality Objectives Monitoring Protocol. The Protocol describes the locations, timing, frequency and methods employed during sampling, as well as the methods used to analyze sampling data. Precipitation data was collected from a variety of sources to assist in the interpretation of results. The water quality objectives monitoring program relies upon both continuous sampling and grab sampling. Continuous sampling is performed by automated instruments that pump water from the creek or river at a preset volume and at precise times each day. Grab samples are taken by personnel at a selected location, depth and time. Normally the quantity of water taken is sufficient for all the physical and chemical analyses that will be done on the sample. Grab sampling is also performed during sampling "blitzes", when single grab samples are collected from as many sites as possible within a short timeframe in order to get a snapshot of the water quality in a watershed over a 24 hour period.

Environmental test results, including physical, chemical and biological analyses of samples taken from water, air, solid waste discharges and ambient monitoring sites throughout the province. Samples are collected by either ministry staff or permittees under the Environmental Management Act and then analyzed in public or private sector laboratories. Code information Support Tables are available on the EMS [website](https://www2.gov.bc.ca/gov/content?id=90A61A67831A4D108859FF77E74C2D4A). The environmental monitoring locations are available in this [geographic dataset](https://catalogue.data.gov.bc.ca/dataset/634ee4e0-c8f7-4971-b4de-12901b0b4be6).

A shapefile of freshwater water bodies hat have been sampled as part of the Nova Scotia Lake Survey. The Nova Scotia Lake Survey program is a partnership initiative between Nova Scotia Environment (NSE) and Nova Scotia Fisheries and Aquaculture (NSDFA) to inventory lakes throughout the province determining baseline water quality, in support of both sport fisheries and water resource management areas.
