As part of an effort to monitor the earthquakes triggered by reservoir loading, we installed two portable seismographs of the neighborhood of the La Romaine 3 reservoir in the Province of Quebec, Canada. The La Romaine hydro-electric complex involves the construction of four dams by Hydro-Québec. The digitizer is located in the black container and it is connected to three short period seismometers to the left. The backdrop of the picture is the 95 m high La Romaine 3 dam (located at latitude 51.12 N; -63.42 W). The 38 km2 reservoir filled up very quickly following snow melt in early May 2017. As of July 18th, 2017, only a few small reservoir-triggered earthquakes have been recorded.
