<br />Reservoir Area Approach Recommendations
<br />The GIS approach to reservoir surface area determination is recommended over the decree
<br />approach for the following reasons:
<br />• The purpose of aggregating non-key reservoirs for the consumptive uses and losses
<br />reporting, water budget analyses, and surface water modeling efforts is to determine
<br />evaporation based on reservoir surface area. The GIS approach is the most direct way to
<br />determine reservoir surface area.
