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.

About Leslie Creek near McNeal, AZ.
Leslie Creek - a temporary flow in the arid Southwest.
Leslie Creek meanders near McNeal, Arizona, offering a glimpse into the dynamic water patterns of the region. This river, draining roughly 79 square miles of the adjacent Whitewater Draw watershed, plays a notable role in the local hydrology, particularly during the summer and winter runoff seasons.
The watershed context
The Whitewater Draw watershed, home to Leslie Creek, experiences the dramatic weather shifts characteristic of the arid Southwest. Summer monsoon thunderstorms can transform normally quiet channels into torrents, leading to flash flooding. Conversely, during the winter months, meltwater from higher elevations feeds into the creek, sustaining flow. However, between these events, Leslie Creek often runs dry, highlighting the ephemeral nature of its waters and the resilience of the unique ecosystems that rely on this intermittent resource.
Why the data matters here
Understanding the flow data for Leslie Creek is crucial for managing both natural resources and potential flood risks. The U.S. Geological Survey (USGS) monitors streamflow at this location, providing vital information on water levels and discharge. Today's reading serves as an important benchmark, allowing users to compare current conditions against the historical median for this calendar day over the past 50 years. This comprehensive context is essential; it enables local stakeholders, whether they be cottagers, farmers, or flood-watchers, to make informed decisions based on water availability and flood potential in this rapidly changing 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.
