Phytoplankton is an important and limiting food source in the Sacramento-San Joaquin Delta and San Francisco Bay; the decline of phytoplankton biomass is one possible factor in the pelagic organism decline and specifically in the decline of the protected delta smelt. The bivalves Corbicula fluminea and Potamocorbula amurensis (hereafter Corbicula and Potamocorbula, respectively) have been shown to control phytoplankton biomass in several locations throughout the system, and their distribution and population dynamics are therefore of great interest. As one element of the Department of Water Resources' (DWR) and the Bureau of Reclamation’s (BOR) Environmental Monitoring Program (EMP), the benthic monitoring program...

These data were compiled to describe population reproductive structure of rainbow trout in the Colorado River downstream of Glen Canyon Dam, Arizona. Objective(s) of our study were to describe the population on reproductive structure of the rainbow trout population in Glen Canyon on the Colorado River and evaluate the accuracy of nonlethal methods (manual expression and ultrasonography) for assigning sex and reproductive phase. These data represent samples collected in 3 sampling trips fall in October to November 2018, February 2019, and April 2019. These data were collected in Glen Canyon, from Glen Canyon Dam to Lees Ferry on the Colorado River. Specifically, we sampled three reaches within Glen Canyon to represent...
