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.

Water Stories

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.

About Kawa Str at Kaneohe, Oahu

Kawa Stream - A vibrant waterway on Oahu's windward coast.

Nestled on the windward side of Oahu, Kawa Stream flows through lush landscapes that thrive in the region's tropical climate. Known for its rapid response to rainfall, this stream is characteristic of Oahu's hydrology, where steep basins can lead to swift water rises during rain events. Flash floods can occur quickly, reflecting the dynamic interplay between the island's weather patterns and its waterways.

The watershed context

Kawa Stream is part of the Oahu watershed, draining an area of approximately 1.1 square miles above the station. This modest drainage area contributes to its quick fluctuations in water levels, especially during heavy rainfall driven by trade winds and Kona storms. These meteorological phenomena often deliver intense downpours that can lead to dramatic changes in the stream's flow. The stream also shares its landscape with several peers, including Heeia Stream and Kahaluu Stream, each bringing their own characteristics to the diverse network of water bodies on the island.

Why the data matters here

Monitoring the water levels at Kawa Stream is crucial for understanding local flood risks and environmental conditions. Today's levels compared to the historical median for this calendar day provide valuable insight into current conditions. By examining this data—reported by the U.S. Geological Survey (USGS)—we can better anticipate natural events and prepare for potential impacts. This contextual comparison helps in assessing water behavior over time, making it a vital tool for local residents and water resource managers.

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.
