The Credit River is special and an essential asset to Southern Ontario.  
The river is over 90 km long and begins as springs from above the Niagara Escarpment near Orangeville and grows to it's outlet at Port Credit where it flows into Lake Ontario.  When you combine all the tributaries of the Credit they exceed 1,500 km in length!

The Niagara Escarpment is the most distinctive landscape feature in the watershed: a scenic rocky ridge 725 kilometres long, winding its way from Queenston near Niagara Falls, through the centre of the Credit River Watershed.   It is recognized as a World Biosphere Reserve by the United Nations Educational Scientific and Cultural Organization (UNESCO). 

The Oak Ridges Moraine is a prominent sand and gravel ridge that forms the major drainage divide between Lake Ontario and Lake Simcoe–Georgian Bay. The moraine is often referred to as “the rain barrel of southern Ontario,” as it is an important source of fresh water and contains the headwaters of many streams and rivers. 

The fishery of the Credit River is an essential component of the ecological health and sustainability of the entire Credit River watershed.  The Credit is one of the most popular angling rivers in Ontario with a variety of fishing opportunities found throughout the watershed.  The coldwater fishery in the upper watershed provides high-quality fly fishing opportunities for brook trout and brown trout.  It is also one of the few places in southern Ontario where you can cast for brook trout in a natural setting.  The lower watershed is known for its spectacular runs of migratory species such as chinook salmon, coho salmon and rainbow trout.  Small lakes and ponds scattered throughout the watershed also offer panfish, bass and pike fishing opportunities.
