Click on the purple dots to see a graph of the stream flow for that gage.

Data Source, USGS.  

Data Source, DNR,  and  DNR, thank you Ann Bleed for helping locate the data.

We use the median stream flow.

It is important to note when the gage was put in place.  The color of the line is highly dependent on when monitoring started.

Flows are given in cubic feet per second.  The annual acre feet equivalent can be computed by multiplying the cubic feet per second by 723.97.   The daily acre feet equivalent can be computed by multiplying the cubic feet per second by 1.983. 

The portion of the rivers colored green have seen an increasing trend in stream flow since the gage was installed. The portion of the rivers colored blue have seen a neutral trend in stream flow since predevelopment.  Only the Republican and all of its tributaries have seen a decreasing trend in stream flows.

Overall, the Nebraska surface water situation is very good with the exception of the Republican River Basin.  The reason the Platte is red between Kingsley Dam and North Platte because the data began in the early 1930s and these years had large flows.  If the gage had been put in two years later then the trend line would have been flat.

Note, the Arikaree and Sappa originate outside of Nebraska and have most of their streambed outside of the State.  These two tributaries are now virtually dry.  Even though the Frenchman Creek has an 80% decrease in flow since the 1930s, it is now the primary tributary to the Republican River.  Even though Kansas has dried up the Sappa Creek it has no obligation to Nebraska.
