USGS Real-Time Gauge Heights - An easy way to see the current gauge heights and discharge for most gauges from Rulo, NE to St. The National Weather Service uses this and other data to create river forecasts.
The US Geological Survey is the federal agency that installs, maintains and distributes data from the river gauges. This means if the weather forecast says it's going to rain for the next four days, only the first day of rain will be included in the river forecast. NOTE - NWS Missouri River forecasts usually include 24 hours of predicted precipitation (sometimes in winter and during floods, they may increase that to 48 hours - you will see the correct number above the forecast hydrograph). When looking at hydrographs on the NWS Advanced Hydrologic Prediction Service website, you can often see information such as river height projections, historic crests, recent crests, and what flood impacts happen at specific river levels in your area. Once you know which river level means what for your area it will be easier to correlate gauge height to river conditions. This is because "0" stage for each location was selected somewhat randomly at some time in the past the number has no direct relationship to the depth of the river or to the stage height at other gaging stations. On the left side of the y-axis is the river stage (displayed in feet) and on the right side of the y-axis is flow (displayed in kilo cubic feet per second).Īs you change from river gauge to river gauge, you will sometimes notice quite a difference in the stage height even though the gauges are relatively close together. On the x-axis is the date and time of the gauge reading. When looking at a hydrograph of your favorite river gauge you will notice a couple of things.
