- Safe Yield
- With reference to either a surface-water or groundwater supply, the safe yield is typically considered to be the maximum rate of continuous diversion or withdrawal that can be maintained indefinitely without depleting the supply. In some cases, the safe yield may be defined for a specified duration when the resource is not used for a continuous supply. Analogous to Practical Sustained Yield and Reservoir Net Yield. Such definitions potentially ignore natural groundwater discharge to surface waters, the reduction in instream flows caused by groundwater withdrawal, or impacts on existing wells. Therefore, the ISWS will no longer use these terms. Instead, the ISWS elects to use the term Yield and explicity state all conditions and assumptions that stand behind the determination of it.
