he lakes and rivers that we fished in eastern Ontario were variable in size, varying in area from Constance Lake, measuring 325 acres, to Centennial Lake, measuring about 8000 acres. The lakes in eastern Ontario that we fished, in general, were formed by past human activity of damming up rivers and creeks. Thus, many lakes in this area are, in reality, reservoirs. They are not glacial lakes, like so many in northern Ontario. The activities of Colonel By and the construction of the Rideau Canal from the Ottawa River at Ottawa south to the St. Lawrence at Kingston caused a number of changes in the lakes and rivers in eastern Ontario. The main rivers in the area are also dammed up which has caused changes from earlier times. The Ontario Hydro Corporation has control of the water depth of the larger rivers, ie. the Ottawa River and the Madewaska River, in order to properly utilize the dams for creating hydro electrical power with turbines. In certain areas and at certain times the waters of the rivers are extremely dangerous because of the swift currents caused by the opening of the dam's pen stocks. We have indicated where the bodies of water which we fished are located and some general information about them.

The lakes and rivers that we fished in eastern Ontario were variable in composition of species of fishes. Each body of water includes an inventory of species of fish which we obtained from past records of the Ministry of Natural Resources. In any body of water the species of fish change gradually over time, usually years. Our inventory, as listed, is not always up to-date so we have indicated and emphasized what species of fish we caught there. We have not indicated where we caught the fish nor what the bottom hydrography of the waters were.

It is sometimes overwhelming to go on a lake which you have never visited before and try to catch a respectable number of fish. Rivers can be interesting because one never knows what will be caught. Eels or channel catfish have an uncanny way of being caught just when you are fishing hard for smallmouths or northerns. American eels spawn in the Sargasso Sea and their elvers find their way into the mouth of the St. Lawrence River, gradually moving up into the Ottawa, the Mississippi and Madewaska Rivers. They can be caught in these lakes and rivers as adult American eels and it can sometimes be frightening to see them on hooks. We only caught 2 eels over 5 years.

We would like to acknowledge the information of the lake-survey data, the maps and the netting suveys kindly provided to us by staff of the Ontario Ministry of Natural Resources. The outline maps of lakes and rivers, as presented here, were obtained by scanning topographic maps and adjusting them to fit our pages. They are not accurate and not to scale and they should be only used to help locate the bodies of water and ascertain what the water bodies look like, in general.
