While I was cross checking the delineated water shed drainage area for some of the EPA STORET sites with the same latitude and longitude as of USGS sites the drainage area is not the same.

For example EPA STORET

site name: Sny Magill Creek Site #1 (SN01) Org and site id : 21IOWA_WQX, 15220004 HUC Id: 07060003 The delineated drainage area obtained : 3.0107 Sq Km / 1.1624 Sq Miles

USGS SITE with same latitude and longitude

USGS Site id : 05411400 Drainage Area from USGS NWIS web site: 27.6 Sq miles

I have encountered few more sites with drainage areas different.
