"The benefits of ecosystem services that have been foregone in order to achieve other benefits have been measured only in a 1981 study, which projected a loss of nearly one million recreation-based days of hunting, fishing, sightseeing, and boating annually in the current Missouri River dam operating regime." (C4, P74)
"Trends in the demand for ecosystem-based recreation in the Missouri River basin continue to increase" (Executive Summary)
An "easily attainable increase of $10 million in hydropower benefits would exceed the $2-3 million in lost navigation benefits" (C4, P87) from dam operation reform.
"Relaxing the responsibility to maintain navigation flows would make it demonstrably easier to introduce flows for improving river ecology… The case for retaining some navigation might be stronger if navigation were discontinued or less fully supported in those segments where it is economically inefficient."" (Executive Summary)
"Beneficiaries of navigation flows do not have rights to any natural or artificial flows of the Missouri River. The 'navigation servitude' doctrine posits that no individual may assert a property right to the flow of a navigable stream below the high watermark of the stream." (C6, P106)
"Stakeholders with vested interests in tightly controlled systems may wield great political influence and may resist changes to traditional management policies." (C5, P92)
