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.

Fraser River at Steveston Water Level

Live water level, flow, historical records and forecast for Fraser River at Steveston in Canada, BC, Canada, built from official government gauge data.

About Fraser River at Steveston

Fraser River at Steveston - A significant estuarine junction.

The Fraser River, one of British Columbia's major rivers, flows into the Pacific Ocean at Steveston. This tidal and estuarine location serves as a critical point for both ecosystems and human activities. The river’s journey is marked by the dramatic landscapes of the province, and in Steveston, it transitions from fresh to saltwater, creating a unique interface that supports diverse habitats.

The watershed context

The Fraser River's watershed is extensive, encompassing approximately 232,000 square kilometres. This massive drainage area channels water from the surrounding landscapes down to Steveston. The Lower Fraser - Coast region is characterized by its dynamic hydrology, which is particularly influenced by seasonal changes. The timing of snowmelt and rainfall plays a crucial role in shaping the river's flow patterns, especially from May to July during the freshet period.

Nearby, the river shares the landscape with several tributaries and peers such as the Alouette River and the Chilliwack River, which also contribute to the overall hydrology of the region. These connections highlight the Fraser River’s importance as an ecological corridor and its role in downstream ecosystems.

Why the data matters here

Currently, no discharge measurements are available from this gauge, but monitoring the Fraser River at Steveston is essential for understanding its tidal variations and ecological health. As conditions, tides, and river discharge affect both local wildlife and human activity, the data collected at this station helps inform fisheries management and conservation efforts.

Today’s measurements are compared against the historical median for this date, offering valuable context for current conditions. Understanding how today's readings align with historical data assists in gauging fluctuations that might impact the local environment and broader watershed dynamics. This monitoring is conducted by the Water Survey of Canada, which ensures that the information remains relevant and current for all stakeholders involved.

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.
