The Sacramento Delta provides huge amounts of crucial water to Central valley agriculture and the ever-thirsty Southland but at the expense of Delta fisheries. Maven, who publishes indispensable California water blog Aquafornia has a detailed article on her own blog about a major new report about aquatic ecosystem stressors in the Delta.
The report classifies the stressors into five general categories: discharges, fisheries management, flow management, invasive species, and physical habitat loss and alteration. Each category has a specified human activity that either initiates or magnifies the stressor.
