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 Gila Gravity Canal at Yuma-Mesa Pumping Plant

Gila Gravity Canal - A vital infrastructure in the Yuma Desert.

The Gila Gravity Canal at Yuma-Mesa Pumping Plant serves as a crucial lifeline in the arid landscapes of Arizona’s Yuma Desert. This canal captures and directs runoff from the greater Gila River basin, a significant water source for irrigation and municipal use in this densely agricultural region. The infrastructure established for water management here reflects the essential interplay between human needs and natural water flow, particularly in a climate characterized by dramatic seasonal shifts.

The watershed context

Located within the Yuma Desert watershed, the canal plays a key role in managing the scarce resources of this area. Though the Gila Gravity Canal is an artificial creation, it takes advantage of the dynamic hydrology of the region, which sees sudden bouts of rainfall from summer monsoon storms. These events can cause rapid flooding, while winter storms and snowmelt from the higher elevations contribute to the seasonal variability experienced across the watershed. It is in this context of variability that the Gila Gravity Canal operates—helping to convey vital water when it is most needed, even as many channels in the region may run dry in between those vital rain events.

Nearby peers like the McAs Diversion of B Canal and the Yuma Main Canal serve similar functions, highlighting the tightly interconnected water management systems that support agriculture in the area.

Why the data matters here

Monitoring the Gila Gravity Canal's discharge is essential for understanding and managing water resources effectively. Being logged by the U.S. Geological Survey, the data collected here helps track the water flow crucial for irrigation demands and flood management.

Today's reading provides significant insight into the canal's conditions, allowing users to compare its flow against long-term patterns. This comparison is important, as understanding current discharge against the median for this day across the station's 21 years of data equips farmers, cottagers, and land managers with crucial knowledge for resource planning and flood preparedness. By gauging real-time data, stakeholders can make informed decisions on irrigation strategies and emergency responses in this dynamic environment.

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.
