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 Bartlett Reservoir at Bartlett Dam
Bartlett Reservoir - a key waterbody in the Lower Verde watershed.
Bartlett Reservoir at Bartlett Dam serves as a crucial resource in Arizona’s Lower Verde watershed, reflecting the intricate balance defined by the region's arid hydrology. As a reservoir, it collects and stores vital water during the sporadic summer monsoon thunderstorms and the seasonal winter snowmelt from nearby highlands. This dynamic creates a lifeline for local ecosystems and meets the demands of the various uses in the area.
The watershed context
The reservoir is part of the Lower Verde watershed, which encompasses an expansive drainage area of approximately 6,157 square miles. The region's hydrological character is shaped by stark contrasts, with channels often running dry between significant weather events. It boasts a network of peers, including the East Verde River, Fossil Creek, and Horseshoe Reservoir, all connected in a tapestry of waterways that respond dramatically to rainfall and snowmelt. This pronounced variability is a hallmark of Arizona's arid landscape.
Why the data matters here
Understanding the data for Bartlett Reservoir is vital for managing water resources effectively in this semi-arid environment. Today's reservoir reading provides a snapshot against the historical median for this date, allowing users to gauge current water levels relative to expected patterns. The monitoring is conducted by the U.S. Geological Survey (USGS), which tracks water levels over a record of 19 years, providing insights that inform agricultural irrigation, flood management, and ecological health in the region.
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.
