Figure 6. Calculated mean ± SE entrainment risk per pipe passage at sweeping velocities of 0.15, 0.38 and 0.61 m/s and water diversion rates of 0.28, 0.42 and 0.57 m³/s.

Significant differences in the number of fish entrained among water diversion rates are marked with different letters (P≤0.006); fish entrainment did not significantly differ among sweeping velocities and there was no interaction.
