Thanks pipeman!
In the beginning of last year the security tried, but since there are no boards indicating that fishing is banned on the Tyger Falls side they didn't have a foot to stand on. For the last few months I havn't had any problems.
Harmony Rowing Club uses the waterfront to row so people are used to seeing canoes on the water. As long as you behave I can't see that they will chase you away on the northen side, but if you fish the southern, Tyger Waterfront, side where fishing is not allowed I think the security gaurds will cahse you away so stick to the Western, northern and eastern sides and you ought to be fine. You can launch from the canoe club's jetty.
