Predicting the effects on endangered mussels from incremental decreases in minimum flows

Assessing environmental flows for mussels


July 2010 - December 2015


The objectives of this study are to determine the level of reduction in minimum flows that affects the behavior, growth, gametogensis, spawning and survival of freshwater mussels. Determine if mussel responses to incremental reductions in flow are of a threshold, linear, or curvilinear nature. Defining sublethal and lethal effects at various levels of flow coupled with hydraulic modeling will allow resource agencies to predict possible effects of any proposed flow reduction, and to prescribe water allocations for endangered mussels based on scientifically defensible data.
