Scientists work to protect B.C. island's crucial freshwater source from fire, drought Social Sharing

Researchers on B.C.'s Salt Spring Island are working on a plan to protect an important freshwater reserve as risks mount amid a growing climate emergency. Maxwell Lake provides water for about half of Salt Spring Island, just off the east coast of Vancouver Island. Ecologists say agriculture and forestry in the area over the past century have left the forest overgrown, blocking out light and limiting the growth of understory, the low layer of vegetation in the forest that helps absorb water.

A second chance: Canada, U.S. renegotiate a critical water treaty

The Columbia River Treaty, an international agreement governing the flow of water between British Columbia and six U.S. states, will be 55 years old this year. It has not aged well. The river springs from the Columbia Icefield in the Rocky Mountains of B.C. and winds 1,930 kilometres through the Northwestern United States – Washington, Oregon, Idaho, Montana, Nevada and Wyoming. No other river in North America spills more water into the Pacific Ocean.
