“The determination of storage-yield relationships for a reservoir project is one of the basic hydrologic analyses for reservoirs. The basic objective can be to determine the reservoir yield given a storage allocation, or find the storage required to obtain a desired yield. The determination follows a traditional engineering approach:^[1]

"Determine the study objectives. This includes the project purposes, operation goals, and the evaluation criteria.^[1]
"Determine the physical and hydrologic constraints for the site. This includes the reservoir storage and outflow capability, as well as the downstream channel system.^[1]
"Compile the basic data. The basic data include demands, flow, and losses. Also, the appropriate time interval for analysis, which depends on the data and its variations in time.^[1]
"Select the appropriate method, one that meets the study objectives and provides reliable information to evaluate results based on accepted criteria.^[1]
"Perform the analysis, evaluate the results, and present the information.”^[1]
