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.

Water Stories

The flood of record that was overtaken

For five years, spring 2019 was the mark every Lake Muskoka decision answered to. In April 2026 the lake went two centimeters higher - and the official books have not caught up yet.

About Sarita River near Bamfield

Sarita River - A vital waterway on Vancouver Island.

The Sarita River flows gracefully near Bamfield on British Columbia's remarkable South Central Vancouver Island. This river not only defines its landscape but also serves as a crucial resource for the local ecosystem and communities. Spanning a catchment area of roughly 162 square kilometers, the Sarita River plays an essential role in the hydrology of the region.

The watershed context

The river is part of the South Central Vancouver Island watershed, which is characterized by its mountain hydrology. In this region, the freshet created from snowpack typically peaks between May and July, marking a period of significant water flow. As spring transitions to summer, the melting snow feeds into the Sarita River, ensuring that its waters remain vital for both wildlife and human use. The nearby peers, including Ash River, Browns River, and Englishman River, share this dynamic spring climate, influenced by the coastal rains and high mountain systems.

Why the data matters here

Today's measurement at the Sarita River near Bamfield provides critical insights into regional water levels and trends. Monitoring the river's flow is essential for understanding its role in the ecosystem and can aid in managing water resources in the area. Current readings compared to the historical median provide a deeper context. The Water Survey of Canada operates this station, and each reading's significance increases when viewed through the lens of historical data. Today’s value, when measured against the median for this date over the past 49 years, reflects not merely the river's elevation at a singular moment but contributes to understanding its seasonal patterns and health.

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.
