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 Lowe R AB Horsetail Falls near Valdez AK
Lowe R AB Horsetail Falls - A Dynamic Flow in Eastern Prince William Sound.
Nestled within the rugged beauty of Alaska, Lowe R AB Horsetail Falls offers a captivating representation of the region's lively hydrology. This river is an integral feature of the Eastern Prince William Sound watershed, flowing through a diverse landscape characterized by steep, forested terrain and glacially influenced waters.
The watershed context
The Lowe River, upstream of the falls, drains approximately 215 square miles (about 558 square kilometers) before its waters descend through this dramatic natural feature. This catchment area supports a rich ecosystem, where glacial melt and rain contribute significantly to water levels, especially during the spring melt. In Alaska, the annual water cycle is dominated by the effects of spring break-up and snowmelt, often leading to dynamic flooding conditions, particularly with the potential for ice jams. Following this demanding seasonal rise, river flows typically diminish in winter, resulting in low flow periods under the ice.
Surrounding the Lowe River are several notable water bodies, including the Lowe River at Rudleston Falls, Mineral Creek, Robe River, and the Valdez Glacier River at Valdez Glacier Lake. Each contributes to the interconnected waterways that define this breathtaking corner of Alaska and presents a unique habitat for both aquatic and terrestrial wildlife.
Why the data matters here
Monitoring the flow at Lowe R AB Horsetail Falls is crucial for understanding fluctuating water conditions within this glacier-fed river. The U.S. Geological Survey (USGS) collects data on discharge, allowing stakeholders such as local cottagers, anglers, and flood watchers to stay informed about water levels in real-time. The insights gained from river monitoring chart patterns and variations in the water's movement, providing valuable information that assists in flood forecasting, maintaining fish habitats, and generally understanding the ecological health of the watershed.
Today's reading can be contextualized against the historical data accumulated over 12 years. By comparing it to the median for this calendar day, users gain a deeper understanding of the current flow's significance, as this measure provides a clearer picture than raw elevation alone. The USGS remains committed to sharing this vital information, ensuring that those who depend on the river are well informed.
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.
