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 Lake Timiskaming
Lake Timiskaming - a vital waterway in Ontario's landscape.
Lake Timiskaming is a significant body of water situated in the Nipissing and Timiskaming regions of Ontario. It serves as a key ecological and hydrological resource in the Upper Ottawa-Kipawa watershed. With its expansive dimensions, the lake connects various waterways and contributes to regional biodiversity, providing habitat for numerous species.
The watershed context
Lake Timiskaming is part of the Upper Ottawa - Kipawa watershed, draining an impressive 45,460 square kilometres above the gauge at Haileybury. This substantial drainage area allows the lake to accumulate snowmelt and rainfall, essential during the spring freshet, which typically occurs from late April through May. Following the freshet, Lake Timiskaming experiences a natural drawdown in the summer months, where evaporation and low inflow lead to gradual water level declines from July to September. Furthermore, as winter approaches, early ice formation marks an initial decline in water levels, characteristic of this region's hydrological rhythm.
Why the data matters here
Monitoring Lake Timiskaming's water levels provides vital insights into the lake’s health and hydrology. Today's reading from the gauge at Haileybury helps contextualize current conditions against the historical median for this calendar day, derived from nearly 49 years of data collection. Understanding where today's measurement stands in relation to the median is crucial for both conservation efforts and local stakeholders, as it helps to indicate trends in water levels that are influenced by seasonal change and precipitation patterns. This data is provided by Water Survey of Canada, ensuring clarity and accuracy in understanding the lake's dynamics.
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.
