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.
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.

Live river level, flow, historical records and forecast for Waikoloa Stream near Kamuela in HI, United States, built from official government gauge data.
Waikoloa Stream - a dynamic watercourse shaped by tropical rains.
Waikoloa Stream meanders near Kamuela in Hawaii, carrying rainwater swiftly through a landscape defined by its steep slopes and quick runoff. This tropical stream, part of a network that includes nearby Alakahi Stream and Kawainui Stream, reflects the unique hydrological patterns of the region, characterized by heavy rainfall that can cause rapid flash floods.
Current monitoring at the Waikoloa Stream station is provided by the U.S. Geological Survey (USGS), which tracks streamflow data crucial for anticipating events associated with Hawaii's rainfall-driven hydrology. The station captures the pulses of water that can escalate quickly, making it essential for local land management and flood forecasting.
The catchment area contributes about 0.9 square miles to the stream's volume, indicating its role in the quick response to rainfall. With data spanning the past eight years, regular updates from this gauge help residents and visitors stay informed, enabling them to navigate the dynamics of the stream safely.
Today's water level provides a snapshot of the stream's current state against the historical median for this day. Understanding this context helps interpret the gauge readings more accurately than raw elevation alone, ensuring those in the area are aware of potential changes in water dynamics and flood risks associated with the tropical climate.
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.
