Geography and geology

Paudash Lake has several different sections within it; Lower Paudash Lake (Outlet Bay) to the east, North Bay to the north, Joe Bay to the southwest and Inlet Bay to the northeast. The lake has a surface area of 7.5 km2 (1,900 acres) and a maximum depth of 46 m (151 ft). Fish species include largemouth bass, smallmouth bass, walleye, lake trout, perch, pumpkinseed, northern cisco, white sucker, and small bait fish of various types.

The area contains over 10,000 lakes which were formed by glaciers some 11,000 years ago during the end of the last ice age. In the heart of the Ontario lake country are the two areas known as "Muskoka" and "Haliburton" (which are both actually a district or county respectively). To many people in Ontario, the area is part of what is known as cottage country, in reference to the some 250,000 summer cottages on the lakes of southern Ontario.

North Bay has massive pink granite, partially tree-covered cliffs, rising hundreds of feet out of the lake along the shoreline. Except in the bare-rock areas, most of the lake's shore is lined with trees and heavy foliage.

Paudash Lake is located within the Canadian Shield. During the last Ice age, glaciers scraped away a 1.6 km (0.99 mi) deep layer of rock, through to metamorphosed sedimentary deposits and the original Precambrian bedrock. As a result, the soil atop the Canadian Shield is typically thin, less than a 30 cm (0.98 ft) deep in many cases. In addition, there is a great deal of exposed bedrock, such as the beautiful cliffs on Paudash Lake.

All of the lakes in the Shield were carved out or sculpted by glaciers, and usually have the characteristically rocky shorelines, although many depressions contain deep glacial deposits in addition to water. In the case of Paudash Lake, the local bedrock is metamorphosed sedimentary rock, including limestone (now marble), which helps to neutralize acid rain .
