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 Gardner Lateral Spill near Parker

Gardner Lateral Spill - A crucial part of the Imperial Reservoir system.

The Gardner Lateral Spill near Parker serves as an important feature within the Imperial Reservoir watershed in Arizona. This spillway channel is part of an intricate system that distributes water within the region, reflecting the unique hydrology of the arid Southwest. Here, the interplay of rainfall and engineered water management is vital for sustaining agricultural and ecological needs.

The watershed context

The Gardner Lateral Spill is situated in a region where summer monsoon thunderstorms can bring sudden and intense rainfall, sometimes resulting in flash floods. Although invigorating at times, these thunderstorms can also lead to dry channels between significant events, underscoring the dynamic nature of water flow in this arid setting. Adjacent waterways, such as the Colorado River and the various canals and drains in the area, further contribute to the complex management of water resources.

The widespread network of irrigation channels like the Palo Verde Canal and the main canal near Parker reflects the region's dependence on water, particularly for agriculture in a predominantly dry landscape. This reliance emphasizes the need for accurate monitoring of water levels and flow, as water can rapidly cycle from abundance to scarcity.

Why the data matters here

Monitoring at the Gardner Lateral Spill is essential for understanding local water dynamics. The USGS collects and shares data on water levels, enabling stakeholders—including farmers and municipalities—to make informed decisions regarding water usage. Today's reading offers a snapshot of current conditions and is compared against the median for this calendar day over more than 50 years of record. This context provides a clearer picture of how the water level stands relative to the historic trends, which is particularly useful in an area where water flow can be highly variable. Consequently, locating and understanding these metrics helps communities prepare for both potential flooding and drought challenges.

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.
