Peer review report 2 on “Hot spring drainage impact on fish communities around temperate estuaries in Southwestern Japan”

1. Original Submission 1.1. Recommendation Minor Revision 2. Comments to Author: 1) It is difficult to imagine a situation where the hot spring water is drained directly or indirectly into the river. Showing some specific cases of the facilities including Onsen-Hatsuden would help the readers to understand the situation. 2) In line 186–189, they mentioned the spike of the electrical conductivity of the Shin River. Adding some discussion from the viewpoint of climate or site location as following or other, this paragraph would be more impressive. For example, the EC spike occurred in 2009 summer, known as the localized heavy rain “Kyushu Hokubu Gouu”. In June 2009, the maximum rainfall in Beppu reached 120 mm per day. As the authors know well, at the side of Shin River, there is Chinoike Jigoku (hot spring pond) where the hot spring water overflows easily in heavy rain. It might be the reason of the EC spike.
