Every five years, water quality is assessed in 32 inland lakes that are greater than 8 hectares in surface area. Samples are collected via helicopter and three key stressors (acidification, eutrophication and metal loading) are assessed using nine parameters [pH, aluminum, calcium, total nitrogen, total phosphorus, dissolved oxygen concentration, iron (Fe), cadmium (Cd) and lead (Pb)]. YSI measurements and Secchi disk measurements are also taken. Samples are sent to the National Laboratory for Environmental Testing (NLET), Burlington, ON, to test for metals and to Natural Resources Canada, Sault Ste.

This measure monitors the trophic state (primary productivity) of six selected lakes, and four selected streams, in order to collect baseline data on processes fundamental to ecological structure and to detect any changes due to ecological stressors.

The park monitors water quality of streams and ponds (lakes) on a triennial cycle, reporting on total organic carbon, acidity, phosphorus, nitrogen, dissolved oxygen, turbidity, and Chlorophyll A. These metrics are compiled into a water quality index (WQI) that summarizes overall water quality.

Water quality monitoring data collected in priority tributaries to provide nutrient concentration data to estimate nutrient loads to the waters of the Great Lakes. Data is collected to advance the science to understand and address the complex problem of recurrent toxic and nuisance algae in the Great Lakes. The majority of the data is focused on Lake Erie, the smallest, shallowest of the Great Lakes, and most susceptible to nearshore water quality issues. Water quality monitoring is conducted to establish current nutrient loadings from selected Canadian tributaries; to enhance the knowledge of the factors that affect tributary and nearshore water quality, ecosystem health, and algae growth; to establish binational lake ecosystem objectives, phosphorus objectives, and phosphorous load reduction targets, and to support the development of a binational nearshore assessment and management framework.

Blooms of filamentous benthic algae that plagued Lake Erie in the 1950s through 1970s were largely reduced through reductions of phosphorus (P) loading from point sources. Since the mid-1990s, these blooms have returned despite a period of relatively stable external P inputs. While increased loadings of dissolved P have been causally linked to cyanobacterial blooms in some parts of the lake, the impacts of ecosystem changes such as the effect of invasive species on nutrient cycling and availability have not been fully elucidated, leading to uncertainty as to the effectiveness of additional non-point P management actions. Here we use the oxygen isotope ratios (δ18OP) of phosphate in concert with measures of water quality along the northern shore of the east basin of Lake Erie to identify sources and pathways of P cycling and infer potential importance in relation to annual blooms of Cladophora that foul the shorelines of eastern Lake Erie.

The integrity of fire-dependent forest types will be maintained through prescribed burns. The park's fire management program uses remote sensing to monitor post-burn changes on the landscape annually. The Area Burned Condition Class measures will be used as per the PCA Fire Monitoring Plan.

The Water Quality Index (WQI), developed by the Canadian Council of Ministers of Environment (CCME) is used to assess the water quality of Pukaskwa’s rivers and streams. Three key stressors (acidification, eutrophication and metal loading) are assessed using nine parameters [pH, aluminum, calcium, total nitrogen, total phosphorus, dissolved oxygen concentration, iron (Fe), cadmium (Cd) and lead (Pb)]. Water samples are collected three times a year (spring, summer and fall) from each sampling site (White River, Willow River, Oiseau Creek, White Gravel River, North Swallow River, Swallow, Cascade River, Tagouche Creek and Imogene Creek). Samples are sent to the National Laboratory for Environmental Testing (NLET), Burlington, ON, to test for metals and to Natural Resources Canada, Sault Ste.
