Some long-term trends are available to see what has changed, or is changing and where we should look if we want to do something about it. In most cases, phosphorus has been a key water quality parameter and has been cited as the culprit when things go visibly awry, whether it is the loss of prey fish, the resurgence of nuisance algae, taste & odour episodes in drinking water or beach closures. There have been two major ecosystem perturbations of the Great Lakes over the past 40 years that have consequences on water quality. Both of these involve phosphorus. The first, in the 1970s, came about with the reduction in phosphorus inputs due to two near-simultaneous events: (1) the regulatory decrease in the phosphate content of detergents; and , (2) Implementation of the bi-national Great Lakes Water Quality Agreement to reduce phosphorus in water pollution control plant (WPCP) effluents to 1 mg/L. The second perturbation resulted from the explosive growth of invasive species in the 1990s, particularly as the dressenid (zebra and quagga) mussels, along with other creatures, such as the spiny (or fish hook) water flea ( Cercopagis pengoi ), a predatory cladoceran that feeds on zooplankton. Paradoxically, and perhaps as a result, phosphorus concentrations in Lake Ontario have decreased over the last four decades: the lake has become more oligotrophic, water clarity has improved, zooplankton concentrations have decreased offshore and phytoplankton production has decreased 1. Paradoxically, there has been a resurgence of nuisance algae ( Cladophora glomerata ). This section reviews the water quality studies on Lake Ontario tributaries and for the nearshore and offshore waters of Lake Ontario, with particular reference to the LOISS area. The historical water quality information is presented in three distinct, if overlapping, periods: The 1960s, the 1990s and following 2000. The area under consideration falls within the Credit Valley Conservation jurisdiction and comprises 13 watersheds that drain into Lake Ontario. These are listed in Table 1, from largest to smallest. All watersheds include a areas of storm sewersheds that either drain into the watercourses or directly into Lake Ontario. These are listed in Table 2. 1 Lake Ontario Lakewide Management Plan 2008, Chapter 1: Lake Ontario Status.

  • Source Protection Annual Progress Report
    DRAFT Attachment 2: 2019 Annual Progress Report Insert Your Logo Here Source Protection Annual Progress Report I. Introduction This annual progress report outlines the progress made in implementing our source protection plan for the Credit Valley, Toronto and Region, and the Central Lake Ontario (CTC) Source Protection Areas, as required by the Clean Water Act and regulations for the 2019 calendar year. Together, these source protection areas comprise the CTC Source Protection Region. Protecting the sources of our drinking water is the first step in a multi-barrier approach to safeguard the quality and quantity of our water supplies. The source protection plan is the culmination of extensive science-based assessment, research, consultation with the community, and collaboration with local stakeholders and the Province. When policies in the plan are implemented it ensures that activities carried out in the vicinity of municipal wells and lake-based intakes will not pose significant risk to those drinking water supplies. Page 1 of 9 Attachment 2: 2019 Annual Progress Report DRAFT II. A message from your local Source Protection Committee P : Progressing Well/Short of Target – The majority of the source protection plan policies have been implemented and/or are progressing; some fall short of target. S : Satisfactory – Some of the source protection plan policies have been implemented and/or are progressing. L : Limited progress – A few of source protection plan policies have been implemented and/or are progressing. This is the third Annual Report on implementation progress of the Drinking Water Source Protection Program in the CTC Source Protection Region since the CTC Source Protection Plan took effect on December 31, 2015.

  • 1 Port Street East Proposed Marina Environmental Assessment Terms of Reference
    1 Port Street East Proposed Marina Environmental Assessment Terms of Reference July 2020 FINAL TERMS OF REFERENCE for 1 Port Street East Proposed Marina Environmental Assessment Prepared for: City of Mississauga Prepared by: Shoreplan Engineering Limited July 2020 1 Port Street East Proposed Marina Environmental Assessment – Final Terms of Reference EXECUTIVE SUMMARY The City of Mississauga (City) is the proponent undertaking an Individual Environmental Assessment (EA) for the 1 Port Street East Proposed Marina Project (1PSEPM). The Port Credit Harbour Marina (PCHM) is currently located on the west portion of the site (the wharf). PCHM is privately operated by Centre City Capital Limited on the wharf leased from Canada Lands Company, the owners of a portion of 1 Port Street East. The PCHM lease is set to expire in 2023 and a future mixed-use neighbourhood is proposed to be developed on the wharf. This development process is expected to be initiated by Canada Lands Company (Canada Lands). The timing of the development of the wharf is dependent on the landowner and related required approvals. The future mixed-use wharf development of the site is not part of this EA. The marina at 1 Port Street East plays an economic and cultural role within the Port Credit community. The issue of how to protect for a sustainable full-service marina as the site is redeveloped into a new mixed-use neighbourhood has become increasingly important. The City is undertaking the 1PSEPM Project to investigate expansion of the land base around the eastern breakwater to provide continued marina function and services at this site, as well as create public access to the waterfront, create new parkland, and enhance the site’s ecological functions.

  • Greenlands Securement Strategy Is an Initiative to Protect the Land and Water of the Credit River Watershed
    Greenlands Strategy Securing our Green Legacy Together we can create an interconnected network of Greenlands for the health and well-being of the environment and future generations Caring for the Credit Conservation through Cooperation Credit Valley Conservation (CVC) was formed in 1954 and is one of 36 Conservation Authorities in Ontario. CVC is a community-based environmental organization dedicated to protecting and stewarding natural resources in cooperation with the communities of the Credit River Watershed. CVC owns and stewards over 2,400 hectares (6,000 acres) of conservation land in the watershed to protect significant ecosystems and offer sustainable natural heritage appreciation and recreational benefits to residents and visitors. Conservation Land Securement Achievements: 1950s - 329 hectares (813 acres) 1960s - 566 hectares (1,400 acres) 1970s - 1,326 hectares (3,277 acres) 1980s - 540 hectares (1,335 acres) 1990s - 39 hectares (97 acres) 2000s - 79 hectares (196 acres) and counting! The Credit River Watershed The beautiful Credit River Watershed spans 1,000 square kilometres of land within the Region of Peel and the Region of Halton. Beginning in Orangeville and Mono above the Niagara Escarpment, the headwaters of the Credit River flow south to the Lake Ontario shoreline, and easterly from Acton to Caledon East. The headwaters are the source of four rivers: the Credit, Humber, Etobicoke and Nottawasaga. The watershed is a diverse and complex system of land and water that provides vital wildlife habitat for 253 species of birds, 46 species of mammals, 5 species of turtles, 7 species of snakes, 19 species of amphibians (frogs, toads, salamanders and newts) and 1,380 species of plants.
