Fox River Historical Analysis
Up to fifteen completed years of seasonal observations, current-year context, and historical ranges from the Fox River monitoring network used to support Conditions products and research.
About the Fox River Monitoring Network
Dive Otter uses a network of USGS mainstem gauges, tributary stations, precipitation stations, dam and tailwater observations, and water-quality measurements to understand conditions across multiple Fox River reaches. The currently collected corridor extends from the upper Fox River through McHenry and Algonquin, then through Elgin, South Elgin, St. Charles, the Geneva and Batavia corridor, and Montgomery.
No single station describes the entire river. Mainstem gauges show how flow and stage change from upstream to downstream, tributary stations identify localized runoff, precipitation stations provide storm context, and water-quality stations supply measurements where continuous evidence is available. Each pool-level Conditions product uses the subset and proxies appropriate to that reach; a station shown here should not be assumed to measure every pool directly.
Long-Term River Context
Historical measurements show seasonal movement, the range observed in individual years, and how the current year compares with available long-term station history.
These charts use the Fox River observation network that supports Dive Otter Conditions products and hydrologic research. Seasonal medians and P25–P75 ranges appear only where a corresponding baseline exists. This is a long-term analytical reference, not a live conditions dashboard.

About These Measurements
Values shown are locally archived USGS observations. USGS observations may be provisional and subsequently revised. Temperature is stored in its original Celsius value and converted to Fahrenheit for display.
Historical charts use up to the fifteen completed years immediately before the current year, with the current year highlighted separately. Continuous measurements are reduced to daily averages and precipitation to daily totals. Where available, the P25–P75 band and seasonal median come from the locally generated seasonal-baseline table. Not every displayed series has or drives a production model baseline.
This page is a generated snapshot. The date shown above identifies how far the current-year overlay extends. Rebuilding the seasonal baselines also regenerates this snapshot.
