Lake Hefner (Oklahoma) water budget data

Lake Hefner is a medium-sized municipal reservoir in central Oklahoma, USA, supplying water to Oklahoma City and nearby areas. The region’s semi-arid climate, with marked year-to-year variability in temperature and precipitation, makes its water resources highly climate-sensitive. Our study used a water balance analysis to assess evaporation from 2000 to 2018, relative to precipitation, inflows, and storage change. The following dataset was used for the assessment.

赫夫纳湖（Lake Hefner）是美国俄克拉荷马州中部的中型城市供水水库，为俄克拉荷马城及周边区域供水。该区域属于半干旱气候，气温与降水存在显著的年际波动，致使当地水资源对气候变化高度敏感。本研究采用水量平衡分析法，结合降水、入流及库容变化情况，对2000年至2018年的蒸发量开展评估。本次评估采用了如下数据集。
