It does describe the environmental efforts - the managers of the dams have been managing it to mimic the normal flow of the river before the dams were built: .... The Corps began to utilize the dam system to mimic the previous flow cycles of the original river, holding back large amounts of water upstream during the winter and early spring in order to release them rapidly as a "spring pulse." The water flows would then be restricted to facilitate a summer drawdown of stream levels. This new policy was highly disruptive to barge traffic and caused frequent localized flooding, but a multi-year drought masked the full impact of the dangerous risks the Corps was taking. This year, despite more than double the usual amount of mountain and high plains snowpack (and the ever-present risk of strong spring storms), the true believers in the Corps have persisted in following the revised MWCM, recklessly endangering millions of residents downstream. .... The problem is that filling the dams during the winter so they could produce the 'spring pulse' means the dams don't have the capacity to handle the snowmelt from a heavy winter like they just had. It's obvious to any reader what the problem is. Why are you denying it?
