Specifications include, but are not limited to: 1. Summarize published literature, focusing on aspects that can inform an assessment of the cumulative impacts of water management strategies on the attainment of environmental flow standards and future environmental flow conditions. 2. Describe the methodology to be used to assess the cumulative impacts of implementing water management strategies, utilizing surface water, as recommended in the 2021 initially prepared regional water plans for the selected river basin. The methodology should include an analysis of impacts for implementation of all relevant water management strategies through 2070 under two future water use scenarios: (1) full utilization of permitted diversions, and (2) partial utilization of permitted diversions.
