32Exception from regulations with respect to the construction of dams, lades and water wheels
(1)No regulations made under this Act with respect to the construction and alteration of dams, lades or waterwheels, so as to afford a reasonable means for the passage of salmon, shall apply to streams or branches or tributaries of rivers which are of such small size as not to be frequented by salmon, nor to dam dykes which in the average state of the river do not obstruct the passage of salmon.
(2)Where in any intake lade there is a sufficient sluice, it shall not be necessary to remove the said sluice to a higher point of the lade, nor to construct an additional sluice at the intake thereof.
(3)It shall be lawful to lift any heck from out the water as a means of protection during a flood, or when the river is encumbered with ice, or with weeds and floating leaves to an extent to choke the heck.
