[OKGIS] Stream gauge data layer

[Robert Blasing]

I'm trying to get an estimated historical inflow into a small reservoir
in a small Oklahoma watershed that has no stream gauges, so I was
wanting a GIS layer with the active and inactive steam gages located
nearest to my location.  I could then select which stream gages may be
the most useful and then go after the historical records for those
gages.  Does anyone know where I could find this?
