In the Discussion, Nash et al. (2019) estimate the seasonal change in groundwater volume for a portion of the restored Sierra Nevada Meadow that we evaluated (Hunt et al. 2018) and use this estimate as an upper bound on the possible contribution to flow that is attributable to restoration. The authors conclude that raising the channel bed elevation and reconnecting the meadow floodplain most likely reduced summer streamflow. In contrast, we report at least a fivefold increase in baseflow from the meadow in the years following restoration. In addition, we observed that, after restoration, the previously intermittent stream below the meadow flowed continuously throughout the summer months, despite record drought conditions, and in 2015, the lowest snowpack on record. We suggest that the groundwater budget presented in the Discussion may not adequately represent conditions within the meadow because the authors extrapolate from 5 near‐channel groundwater wells across 62 ha of meadow and assume an area of influence that is approximately one‐sixth of the meadow area. We conclude that the conversion of an intermittent stream to perennial flow during drought conditions is a stronger check on our gauge data than the groundwater budget presented in the Discussion.

回复讨论

在讨论中，纳什等人。（2019）估算了我们评估过的一部分已恢复内华达山脉草甸的地下水量的季节性变化（Hunt等人2018），并将这一估计值用作归因于恢复的可能流量贡献的上限。作者得出的结论是，提高河床床高和重新连接草甸洪泛区最有可能减少夏季水流。相比之下，我们报告说，恢复后的几年中，来自草地的基流至少增加了五倍。此外，我们观察到，恢复后，尽管有创纪录的干旱条件，草甸下方先前断断续续的溪流在整个夏季持续不断地流动，而在2015年则是有记录以来的最低积雪量。我们建议讨论中提出的地下水预算可能不足以代表草甸内的条件，因为作者从横跨62公顷草甸的5条近渠道地下水井进行了推断，并假设影响面积约为草甸面积的六分之一。我们得出的结论是，在干旱条件下，间歇性水流向多年生水流的转化比讨论中提出的地下水预算更能有效地检验我们的测量数据。
