The High Aswan Dam converted a variable and uncertain flow of river water into a predictable and controllable flow. We use a computable general equilibrium model of the Egyptian economy to estimate the economic impact of the High Aswan Dam. We compare the 1997 economy as it was to the 1997 economy as it would have been for 72 historical, pre-dam water flows. The steady water flow increased transport productivity, while the seasonal shift in water supply allowed for a shift towards more valuable summer crops. These static effects are worth LE 4.9 billion. Investments in transport and agriculture increased as a consequence. Assuming that Egypt is a small open economy, this is worth another LE 1.1 billion. The risk premium on the reduced variability is estimated to be LE 1.1 billion for a modest risk aversion, and perhaps LE 4.4 billion for a high risk aversion. The total gain of LE 7.1 billion equals 2.7% of GDP.
