Easily-calculated metrics describing potential impacts of dams are often used as preliminary investigations, or in analyses describing hydrologic impact over large scales and involving many dams. However, common dam impact metrics overwhelmingly reflect effects of medium to large reservoirs. Indicators applied to describe a dam’s capacity to alter downstream river flows typically consider reservoir storage as a sole mechanism of hydrologic impact. Herein, metrics of hydraulic size are proposed to encompass potential impacts related to both storage and diversion of water. Hydrologic effect due to storage and diversion computed across a sample of diversion and non-diversion dams exemplifies that hydrologic …
