The Alouette River Is One of Maple Ridge's Greatest Assets. It Needs Better Protection Than It's Getting.

The Alouette River watershed provides drinking water, salmon habitat, and recreational access that defines this community. Development pressure and inadequate stormwater management are threatening water quality in ways that demand urgent attention.

The Alouette River runs through Maple Ridge's identity as much as it runs through its geography. It is where the salmon return in fall — still, improbably, in numbers that remind you that this corner of the Lower Mainland retains ecological connections that most of the urban region has severed. It feeds the reservoir that provides Maple Ridge's drinking water. It offers the kind of accessible river experience that urban residents two hours away would drive to find.

It is also under pressure that it is not fully equipped to absorb.

Stormwater from the growing residential areas in the upper watershed carries contaminants — hydrocarbons, sediment, lawn chemicals, road runoff — into tributaries that feed the Alouette. Development approvals in sensitive areas adjacent to the watershed have moved faster than the environmental assessments that would quantify the cumulative impact.

The Alouette Lake reservoir, which provides Maple Ridge's drinking water, has shown increasing turbidity events in recent years. The causes are multiple and their relative contributions are debated. What is not debated is that the watershed is under more stress than it was a decade ago.

Maple Ridge has jurisdiction over land use decisions that affect the Alouette watershed. It has an obligation to make those decisions with the watershed's health as a non-negotiable constraint — not a consideration to be balanced against development revenue, but a line that does not move.
