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.

Yuma Irrigation District 18.4 Lateral Water Level

Live river level, flow, historical records and forecast for Yuma Irrigation District 18.4 Lateral in AZ, United States, built from official government gauge data.

About Yuma Irrigation District 18.4 Lateral

Yuma Irrigation District 18.4 Lateral - A vital water source in the arid Southwest.

The Yuma Irrigation District 18.4 Lateral flows through the arid landscape of Arizona, serving as a key channel for agricultural irrigation in the region. Located within the Lower Gila watershed, this lateral aids farmers in the Yuma area by delivering much-needed water during the growing season. Its significance is underscored by the surrounding irrigation infrastructure, which includes various other laterals and wasteways that collectively help manage water resources in this desert environment.

The watershed context

Within the Lower Gila watershed, the Yuma Irrigation District 18.4 Lateral is among several streams and canals that capture and distribute water. It connects with important peers such as the Bruce Church Wasteway and the Gila River. The channels in this area are heavily influenced by the seasonal hydrology of the Southwest, with summer monsoon thunderstorms creating short-lived but intense flash floods, while winter storms and snowmelt from highlands significantly contribute to river levels at other times of the year. These dynamic conditions underscore the challenge of managing water resources in an area where many channels may run dry between significant precipitation events.

Why the data matters here

As a station managed by the U.S. Geological Survey (USGS), the Yuma Irrigation District 18.4 Lateral provides valuable real-time data on water levels and discharge. Monitoring data helps farmers, irrigation managers, and local authorities make informed water management decisions. Today's reading offers insights into how current conditions compare to the median level for this date over the past 21 years, aiding in understanding seasonal water availability in this crucial irrigation pathway. Such comparisons are vital as they reflect not just raw elevation but also the expected behavior of water levels based on historical trends.

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.
