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 Yuma Irrigation District 18.2 Lateral

Yuma Irrigation District 18.2 Lateral - A lifeline in the Lower Gila watershed.

The Yuma Irrigation District 18.2 Lateral serves as an essential conduit in the Lower Gila watershed, reflecting the intricate interplay between human management and the natural dynamics of arid southwest hydrology. This lateral, part of a broader irrigation system, demonstrates the ongoing efforts to harness water resources for agricultural purposes in a landscape characterized by seasonal extremes.

The watershed context

Situated in Arizona, the Yuma Irrigation District 18.2 Lateral is part of the Lower Gila watershed, which is deeply influenced by the region's arid climate. Water flow in this system is predominantly affected by seasonal rainfall brought on by summer monsoon thunderstorms, which can create sudden and intense flash floods. Conversely, winter storms along with snowmelt from higher elevations contribute further inflows to the larger rivers, though many smaller channels may run dry in between these sporadic events. This dynamic makes the lateral critical for irrigation, particularly in areas where water availability can fluctuate significantly.

Why the data matters here

Today, the water level at the Yuma Irrigation District 18.2 Lateral is carefully monitored by the U.S. Geological Survey (USGS). Understanding the current reading in relation to the historical median for this calendar day over the last 21 years provides valuable insight into the lateral's performance and the current state of water availability. This contextual information helps users, from farmers to flood-watchers, make informed decisions based on shifting conditions. The operational insights gained from ongoing measurement are indispensable in managing agricultural demands and preparing for potential flooding during monsoon events.

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.
