Aquatic systems in semi-arid Brazil include three major groups of environments: intermittent streams
and rivers (except for the perennial Sao Francisco River and artificially regulated rivers) (Maltchik and Medeiros, 2006a), natural shallow lakes (Maltchik et al.
all other waters such as intrastate lakes, rivers, streams (including intermittent streams
, mudflats, sandflats, wetlands, sloughs, prairie potholes, wet meadows, playa lakes, or natural ponds) the use, degradation, or destruction of which could affect interstate or foreign commerce including any such waters: (i) Which are or could be used by interstate or foreign travelers for recreational or other purposes; or (ii) From which fish or shellfish are or could be taken and sold in interstate or foreign commerce; or (iii) Which are used or could be used for industrial purpose by industries in interstate commerce.

But a state Fish and Game warden told him to stop, saying he could be changing the course of the intermittent stream

Time and space prohibit an exhaustive discussion of all of the requirements but isn't it comforting to know that even in a small hog farm the lagoon storing waste has to be at least 200 feet from its neighbors well, lagoons have to be 100 feet from an intermittent stream
and a whopping 1300 feet from the waters of this State including critical habitat waters and shellfish harvesting waters.
