The Art and Science of Instream Flows
Instream Flows is the art and science of collecting data in systems we cannot adequately sample using methods developed by committees of technically unqualified participants for organisms we know very little about in order to form concepts about processes we do not fully understand that we represent as mathematical abstractions that we cannot precisely analyze to determine their responses to indeterminate stresses we cannot accurately predict now let alone in the future all in such a way that society at large is given no reason to suspect the extent of our ignorance.
