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 Baltimore Creek at Baltimore
Baltimore Creek - A dynamic small river in Ontario.
Baltimore Creek flows gracefully through the heart of Ontario, a vital watercourse within the Ganaraska watershed. This creek, with a drainage area of roughly 41 square kilometres, serves not only as a natural feature but also as an important resource for the surrounding communities and ecosystems.
The watershed context
Baltimore Creek sits amid a network of waterways that collectively define the Ganaraska watershed. This area is connected to several peers, including Bowmanville Creek, Cobourg Brook, and the Ganaraska River. Each of these streams plays a significant role in the broader ecology, contributing to the diverse landscape while supporting local agriculture, recreation, and wildlife habitats. The creek is notably influenced by the typical seasonal rhythms of Ontario's climate, notably the spring freshet that peaks in late April to May. During this time, snowmelt enriches the waters, ensuring that the creek is vibrant and full.
As summer unfolds, a natural drawdown occurs between July and September, leading to lower flows as evaporation takes its toll and inflow decreases. Early winter also brings a drop in water levels as ice begins to form, marking the cyclical changes that Baltimore Creek experiences throughout the year.
Why the data matters here
Assessment of Baltimore Creek's water levels is critical, particularly as it relates to the station's daily readings. Today’s measurement at Baltimore Creek is instrumental in understanding the status of the creek's health and behavior. By comparing the current water level against the historical median for this date across more than 20 years of records, one gains insight into flood risks, seasonal trends, and ecological changes. This comparison, maintained by Water Survey of Canada, provides invaluable context that raw readings alone cannot offer, ensuring informed decisions can be made by cottagers, anglers, and flood-watchers 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.
