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 Costilla Creek above Costilla Dam

Costilla Creek - An essential stream in the Upper Rio Grande watershed.

Flowing graciously through northern New Mexico, Costilla Creek plays a vital role in the local hydrology of the Upper Rio Grande watershed. This reach, positioned above Costilla Dam, not only supports the ecology of the area but also captures the moisture dynamics characteristic of the arid Southwest.

The watershed context

The Upper Rio Grande watershed encompasses a diverse array of terrains and water bodies, with Costilla Creek serving as a smaller but important tributary. This creek is crucial for local water flow, draining approximately 25.1 square miles of land above the measuring station. The region experiences significant variability in its hydrological patterns, principally driven by high-country snowmelt in the spring and the occasional, intense summer monsoon storms.

Nearby, other tributaries like Alamitos Creek and Casias Creek complement the hydrological landscape, contributing to the richness and connectivity of aquatic habitats in the region. The interplay of Costilla Creek with these peers underscores its importance as a tributary capable of carrying not only water but also supporting the natural ecosystems that thrive alongside its banks.

Why the data matters here

Data from the USGS station measuring Costilla Creek provides critical insights into stream conditions and local hydrology. These readings help monitor the flow and water levels, which are crucial for various users including local farmers and environmentalists. Comparing today’s water level against the median for this calendar day enriches our understanding of seasonal variations and broader climatic trends. Today's reading will reflect how this stream is performing relative to what has been typical over the past fifty years, enhancing our ability to respond to changing water availability patterns.

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.
