3.5 Additional data
Drive-point piezometers (1.9 cm inside diameter) were installed within the second spring branch (P2), below AWS1 (P3), to the west of the stream between GS1 and GS2 (P4) and in the lakebed (P5) (Figure 1). Pressure transducers (In-Situ, MiniTroll, accuracy ~1 mm) were placed in the piezometers to measure groundwater levels and temperatures. Continuous water level data were verified bi-weekly with manual water-level measurements. Lake water level was measured by a pressure transducer (Solinst, Levelogger, accuracy ±0.3 cm), in a lake stilling well. Stream dimension surveys were completed on June 26 and August 2, 2019 whereby stream depth was recorded every 10 cm along the width of the stream, at 24 separate transects. Twelve transects were located between GS1 and GS2 at approximately 20 m intervals and the remaining 12 transects were located at approximately 50 m intervals between GS2 and GS4. The width of the transects ranged from 1.3 to 4.4 m.
