Scientific evidence is supposed to be part of federal court jurisprudence under Supreme Court case law. Except when greedy Temple Destroyers, as John Muir would call them, want to plow under wetlands.
From Mother Jones:
Supreme Court Wetlands Ruling Defies “Scientific Understanding”
It excludes bodies of water federal law “has always been interpreted to cover.”
Like icebergs and human beings, waterways are made up of more than what’s visible on the surface. Take Lapwai Creek, near Lewiston, Idaho: At a casual glance, it’s a ribbon of cool water, shaded by cottonwood trees and alive with steelhead and sculpin, mayfly and stonefly larvae. An adult could wade across it in a few strides without getting their knees wet. But that’s just the part people can see. Beneath the surface channel, coursing through the rounded cobbles below, is what scientists call the hyporheic zone: water flowing along underground, which can be a few inches deep, or 10 yards or more, mixing with both surface water and groundwater. Microbes that purify water live down there, and aquatic insects—food for fish and other animals—can use it as a sort of underground highway, traveling more than a mile away from a river.
A creek, in other words, is more than just the water in its channel; it’s also the water underground, and it’s connected to everything else in its watershed, including wetlands and channels upstream that might dry up during some years, or perhaps go years between getting wet. Whatever happens there—pollution or protection—happens to the entire creek. In the case of Lapwai Creek, which flows into the Clearwater River and then the Snake River, it’s a small but fundamental part of the complex ecosystem that salmon, humans and countless other creatures in the Pacific Northwest rely on.
