records relate to water quality and fish research in northwestern ontario.

in 1986, the international joint commission’s remedial action plan for the great lakes designated four canadian areas of concern (aoc) in lake superior. the following areas were identified to have water quality impairments, thunder bay, nipigon bay, jackfish bay, and peninsula harbour (marathon, ontario). pulp and paper mills were identified as a major source of pollution. in thunder bay, the inventory and assessment projects were initiated as stage 1 and completed by 1991. stage 2, remedial strategies, completed in 2004. general issues: unpleasant foam, oily residue, and odour in waterways, high levels of chemicals in sediment and fish, loss of fish and wildlife habitat, impacts to sediment-dwelling organisms, and impacts on fish populations. specific fish habitat concerns were water quality degradation, loss of wetland, degradation or loss of spawning substrate, and habitat destruction by dredging. important fish population problems have occurred over time due to fish habitat loss from both physical and chemical changes on lake superior and its tributaries.
many government agencies were involved with lake superior remedial action plans including the ministry of the environment (moe), department of fisheries oceans (dfo), ministry of natural resources, and the lakehead conservation authority. 阿根廷vs墨西哥竞猜 was tasked with portions of the fish and fish habitat inventory in stage 1 and providing an external review of the stage 2 plans for remedial action. 阿根廷vs墨西哥竞猜 sought dr. walter momot, professor of ichthyology with this responsibility.

this collection is divided into three series involving the international joint commissions remedial action plans of the canadian portion of lake superior.
1) kaministiquia river project
a. kaministiquia river external reports
2) northwestern ontario fish inventory collection
3) remedial action plan reviews
