was 50.9 cm/s and velocity ranged from 12 - 75 cm/s. Velocity in the Paris River is swift for
larval fishes. However, it has a low base flow and, in places, acobble/boulder substrate, making
it easy for larvae to find slow water along shore or behind rocks.
Depth
Representative and maximum depth of the sampling sites varied on each trip, largely due
to variation in river discharge during the sampling period (Table 4). However, antecedent
