Pitt River rules?

I'm usually good at reading and understanding hunting regulations, but this one has me flummoxed

The signs on the dikes at Pitt River say it is "Closed to the discharge of firearms on the right of way of the dike" or something similar.

Pitt Meadows municipal law says you cannot discharge a firearm within 150 metres of a park. The dikes along the river are not park land are they?

There are municipal rules and Fraser Valley regs as well prohibiting the discharge of firearms towards shore.

So:

Can we still legally go down to the shoreline of the river in these areas to hunt waterfowl?

and i bet their is a bylaw number on that sign..look it up. i have that where im at for no discharge also. then if you look up bylaw it says im ok with a bow an fraser valley permit.
