1. On January 1, a lake with a surface area of 10,000 hectares has a water surface elevation of 50.15 m above the elevation datum. During the month of January, the average: inflow to the lake is 10.0 m³/s and the average outflow from the lake is 8.5 m³/s. Total rainfall and evaporation are 30.0 cm and 5.0 cm, respectively. Assume that there is no infiltration or groundwater discharge. Write the hydrologic budget for the lake and calculate its water surface elevation (in m above the elevation datum) at the end of January. Round to the nearest hundredth of a meter.
