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.

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.

Redhill Creek at Hamilton Water Level

Live river level, flow, historical records and forecast for Redhill Creek at Hamilton in Canada, ON, Canada, built from official government gauge data.

About Redhill Creek at Hamilton

Redhill Creek - A vital tributary in Hamilton's landscape.

Nestled in the Credit - 16 Mile watershed, Redhill Creek is an important watercourse that flows through Hamilton in Ontario. This creek, with a drainage area of roughly 47.7 square kilometres above the station, plays a crucial role in the local hydrology.

The watershed context

The Credit - 16 Mile watershed is interspersed with various tributaries, including nearby streams like Cooksville Creek and several branches of the Credit River. This expansive network of waterways contributes to the ecological health of the region, serving as natural conduits for rainfall and melting snow. Redhill Creek's seasonal patterns are characteristic of many waterways in Ontario, governed by snowmelt, rainfall, and evaporation influences.

Spring marks a significant phase for Redhill Creek, with a freshet occurring in late April to May due to snowmelt. Following this period, the creek naturally experiences drawdown during the summer months from July to September, as water levels fluctuate with evaporation and reduced inflows. As winter approaches, early declines in water levels begin as the ice forms, shaping the creek's annual rhythm.

Why the data matters here

Understanding the conditions of Redhill Creek is essential for local residents and stakeholders, especially given the creek's discharge measurements, which provide critical insights into the water level variations throughout the seasons. Tracking these fluctuations allows for better management of water resources and aids activities such as fishing and flood monitoring in the region.

Today's reading from the Water Survey of Canada shows how Redhill Creek’s current elevation compares with the median for this calendar day across its 47 years of recorded data. This metric helps gauge how recent conditions align with historical trends, offering more context than mere elevation alone.

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.
