The oceans drain approximately 83% of the land in the world. The other 17% – an area larger than the basin of the Arctic Ocean – drains to internal endorheic basins. There are also substantial areas of the world that do not "drain" in the commonly understood sense.
Watershed delineation is the process of identifying the boundary of a watershed, also referred to as a catchment, drainage basin, or river basin.It is an important step in many areas of environmental science, engineering, and management, for example to study flooding, aquatic habitat, or water pollution.

Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, [3] [4] and impluvium. [ 5 ] [ 6 ] [ 7 ] In North America, they are commonly called a watershed , though in other English-speaking places, " watershed " is used only in its original sense, that of the drainage divide line.
High water periods in the spring flood large areas creating wetland soils and large areas of marsh. As water levels slowly fall, conditions suitable for swamp forests occur. This natural seasonal alternation between high and lower water levels is essential for creating the natural diversity of wetlands along the river.
The surrounding topography of a catchment zone influences the flow vectors and direction that the water flows. [1] Water flows from areas of high potential energy to low potential energy under the influence of gravity. The geometry of the slope leading to the catchment area influences the amount of water the catchment will contain. [1]
The area removed from the park was deregulated and transferred to the Government of Canada for a reserve for the Sand Point First Nation. Lake Nipigon Conservation Reserve - 176,660 ha (436,500 acres) reserve, created in 2003, that includes all Crown islands and most of the shoreline of Lake Nipigon.
