Where are the watershed boundaries for the Shuswap River drainage? Map

Description

The watershed of the Shuswap River begins in the east close to the Arrow Lake reservoir, south of Revelstoke. It starts high up in the Monashee mountains. Greenbush Lake is the area where it begins. The water flows south through Sugar Lake reservoir past Cherryville and then on to Lumby. Many other creeks join the river including Bessette whose drainage begins south east of Vernon in the Greystokes area (Duteau, Harris, Creighton). The river then flows north picking up more water until it empties into Mable Lake. Near the north end the lake Wap Creek contributes its waters that start in the north close to three valley gap. All of these waters flow east toward Enderby. Here the river turns north again gathering water from the Fortune Creek watershed that starts just north of  Armstrong where there is a cairn off the highway marking the watershed divide. South of here all the water flows into Okanagan Lake finally emptying into the ocean in the United States. At Mara Lake all the water gathered from the catchment area (Shuswap River Watershed) flows here.

Here is a map of the total watershed area of the Shuswap River with individual watersheds marked.
