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 Eramosa River above Guelph
Eramosa River above Guelph - A vital waterway in the Upper Grand watershed.
The Eramosa River, flowing gracefully above Guelph, is an important tributary in the Upper Grand watershed of Ontario. This river plays a key role in the regional hydrology, acting as a conduit for the melting snow and seasonal rains that characterize the area. With a drainage area of approximately 234 square kilometres above the station, it supports both local ecosystems and recreational activities like fishing and kayaking.
The watershed context
The Upper Grand watershed, where the Eramosa River resides, is known for its intricate network of waterways, including nearby companions such as Blue Springs Creek, Canagagigue Creek, and the Grand River. This region experiences snowmelt-driven seasonal hydrology, with a notable spring freshet occurring from late April to May due to the thawing snow. As summer approaches, natural drawdown takes place from July through September, driven by evaporation and reduced inflow. Early winter brings a decline in water levels as ice begins to form, making for distinctive seasonal shifts in the river's character.
Why the data matters here
Monitoring the Eramosa River provides valuable insights into water conditions in the region. The station, which measures discharge, helps track changes relevant to river health, aquatic life, and water quality. A key indicator of current river conditions is the day's water elevation compared to the median for this date across its more than 50 years of recorded history. This approach offers a clearer understanding of hydrological changes as it reflects the river's behavior relative to an established norm, rather than just a single reading. The operation of this station is managed by the Water Survey of Canada, ensuring that data remains reliable for local stakeholders and conservationists alike.
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.
