Water quality and ecosystem health data are collected in the nearshore zone of the Great Lakes to address the problem of nuisance benthic algae. Monitoring data include physical and chemical water quality data as well as biological data, primarily from Cladophora and dreissenid mussels on the lakebed. Monitoring is conducted (i) to improve understanding of the factors impacting nearshore water quality, algae growth, and ecosystem health; (ii) to develop ecosystem health indicators for the nearshore; (iii) to provide validation and calibration data for modelling; (iv) to support the development of a binational nearshore assessment and management framework; and, (v) to measure the success of ongoing and future phosphorus reduction targets to support a healthy ecosystem.
Marine mammal predator control is governed by the Marine Mammal Regulations under the Fisheries Act. Records of marine mammal mortalities are maintained and results reported publicly. Additional licences can be obtained for control of other species. Fisheries and Oceans Canada works with industry to improve marine mammal deterrent and control measures.

To be healthy, we need to eat a variety of foods, especially fresh fruits and vegetables. Pesticides play an important role in making sure there is enough food for everyone, by protecting crops from pests like insects, weeds, and fungal diseases. While pesticides help protect our food supply, some people have concerns about pesticide residue that may be on the food they eat.

All available bathymetry and related information for Graveyard/Cache Lakes were collected and hard copy maps digitized where necessary. The data were validated against more recent data (Shuttle Radar Topography Mission 'SRTM' imagery and Indian Remote Sensing 'IRS' imagery) and corrected where necessary. The published data set contains the lake bathymetry formatted as an Arc ascii grid. Bathymetric contours and the boundary polygon are available as shapefiles.
