Maltby Lake is located on southern Vancouver Island, British Columbia. It is located 10 km north of Victoria, British Columbia in the Tod Creek Watershed. The lake is the headwaters for the watershed, which eventually feeds the world class Butchart Gardens.
Maltby Lake is a pristine freshwater source in the middle of a semi rural developing area on the Saanich Peninsula on Vancouver Island. The lake and the surrounding area of pristine land hosts an abundance of wildlife, exotic aquatic life (including freshwater jellyfish) and one of the largest Douglas fir trees in the Greater Victoria area.
For almost a century, until 2008, the lake and surrounding lands had been owned by a single extended family, which developed the property minimally. The first dwelling, an 1860s hunting cabin turned farm house, still stands. Motorized watercraft have been banned by the family since the '50s; the lake provides a potable drinking water source for the few residents there. As land taxes continue to rise (in the order of 500x in the last 40 years), the owners endeavour to maintain this idyllic setting.
Maltby Lake is the most important water body in the Tod Creek Watershed and possibly on the entire Saanich Peninsula. It contributes to the catchment area of Tod Creek which is estimated to be 22.8 km2 (8.8 mi2). Maltby Lake, Prospect Lake, Durrance Lake and Quarry Lake are all in the Tod Creek drainage area.
Several studies have been conducted on the lake, including a Camosun College environmental study, a PhD on frogs and an ongoing study on the hydrology and hydrogeology of the lake.
