| Water depth (cm) | 13.9 ± 9.4 | 12.8 ± 5.0 |
| pH | 8.1–8.5 | 8–8.2 |
| Dissolved oxygen (mg L−1) | 9.4–11.5 | 9.9–11.4 |
| Water flow velocity (m s−1) | 0.05–0.8 | 0.05–0.6 |
| Water temperature (°C) | 15.1 ± 0.8 (13.6–16.1) | 15.5 ± 0.8 (14.2–16.9) |
| Water level (cm, during behaviour measurements) | 10.76 ± 4.2 | 10.37 ± 6.00 |

Measurements for width, depth and flow velocity were made during crayfish recapture surveys in September of each year, while measures of pH, water temperature and dissolved oxygen were made from early August to late September. Measurement method details are available in the supplementary methods.
