One of my best friends, a newly retired water quality scientist with the USGS, says the pond looks illegal to him, so I'm going with the guy who was sent to Sarajevo years ago to restore Bosnia/Herzegovina's waterways after the war. I'd be interested in hearing his take on this given the pond does not drain into protected wetlands, nor does the following tributary, or the one after. An examination of the hydrology records on the EPA filing yields the following results:
Pond receives zero water from a river. Six Mile Creek is the drainage location and recognized as an irrigation duct. It's average width is 29 inches and isn't deep enough for consistent volume monitoring. This drains into Blacks Fork, also not a protected wetland, that drains to Meeks Cabin reservoir.
Blacks Fork does not even come close to be considered a "watershed" to the closest protected wetland, and it isn't even where the Pond in question drains to initially:

The EPA conceded that Six Mile Creek lacked "direct nexus" to any wetlands since Blacks Fork doesn't have a measurable volume to indicate such. This led to their agreement to settle, their own evidence lacked the evidence they needed. ACoE provided data that Six mile doesn't even reach Blacks Fork multiple times per year.
Interior Region 7 (Where this pond exists) of the The Bureau of Reclamation uses this case in training. Their stance is that the EPA incorrect in their assessment, they use US law and the court case as reference, then show the methods for volumetric analyzation for use in US Court. Projects, Operations and Modeling Division clearly states there was no data supporting the language in the CWA in regard to "
no significant nexus to a navigable water" - that being, at the closest Meeks Cabin Reservoir.
So how is the pond illegal?
