Nibi Metrics

Real-time water levels, forecasts, and alerts for lakes and rivers across Canada and the US. Built on official government data.

Nibi Metrics turns raw gauge readings from official hydrometric networks into something a person standing on a dock can actually use: is the water high or low for today, which way is it moving, and how unusual is this? This page explains where every number on the platform comes from and what we do to it along the way.

About Quinsam Diversion near Campbell River

Quinsam Diversion - a vital tributary on Vancouver Island.

The Quinsam Diversion flows gently near Campbell River, British Columbia, serving as an important watercourse within the East Central Vancouver Island watershed. With a drainage area of roughly 0.85 square kilometres, this diversion contributes to the hydrology of the surrounding region, interlinking with several other significant water bodies such as Buttle Lake and the Campbell River.

The watershed context

The East Central Vancouver Island watershed encompasses a diverse range of ecosystems, where the interplay of river systems, lakes, and creeks creates a vibrant habitat for a myriad of flora and fauna. The Quinsam Diversion, while modest in size, plays a critical role in this interconnected landscape. During the spring freshet, driven by melting snowpack, water levels typically rise, peaking between May and July. The seasonal flow patterns reflect the mountain hydrology of the region, enhancing the natural cycles that support wildlife and influence water quality throughout the watershed.

Nearby, the Campbell River and other tributaries such as the Elk River and Little Oyster River also experience similar seasonal rhythms, attracting attention from anglers and outdoor enthusiasts alike.

Why the data matters here

Today's water level at the Quinsam Diversion is recorded alongside a historical median for this date, derived from over 28 years of data. This context is crucial for understanding current water conditions. By comparing today's measurement to the median for the day, users can gauge the fluctuations in flow that may impact local ecosystems and activities such as fishing or recreational outings. The operating agency, the Water Survey of Canada, provides this vital information, underscoring the importance of accurate water monitoring in managing and preserving the resources of the East Central Vancouver Island watershed.

How this page is built

Readings come from official government gauges and are rolled into daily records: the daily mean, high and low for every day on record. Each calendar day gets its own baseline from the full history, so the level you see is compared against what this specific date usually looks like rather than an annual average.
