A reservoir with a constant surface area of 5.8 km has an elevation of 207.6 m above (mean sea level) MSL at the beginning of the week. Meteorological measurements made at reservoir for the week indicate that the total precipitation accumulation was 101.6 mm and the total evaporation was 72.2 mm. Also, hydrologic measurements made at reservoir indicate that the average river inflow rate is 34.0 m3/s, and the average outflow rate is 26.6
