The watershed of a body of water plays an important role in the health of a lake, river or stream. (A watershed is defined as the entire region that drains into a body of water.) What happens in the watershed will affect the health of the lake. For example clearing as little as 5% of a watershed can result in changes in runoff and affect a lake.

Gardom Lake has a small watershed because there is little higher land surrounding it.
See the Columbia Shuswap Regional District's map of the watershed of the lake. LINK
Gardom Creek, which runs along Mallory Road, is the only inflow creek to Gardom Lake and is an important part of the lake's watershed. It flows seasonally during the late winter and spring, depending on temperatures and the amount of precipitation. One of the recommendations of the Gardom Lake Management Plan was the restoration of this creek to help restore some of its original functions.
Work is being planned for the mouth of the creek which will include relocating the creek to its original alignment, planting riparian vegetation, restoring a wetland area and livestock fencing.
