I do agree with you YOTE that it is a "put and take fishery". However, IMHO, the south island lakes can't sustain hundreds of anglers hitting the lake for a day and bonking fish.
Elk Lake is one of the few lakes left in an urban environment that hold trophy fish. Although the lake is considered large for South VI, it’s not actually that large.
I'm not sure if the Langford Lake Derby is still running but I can remember the damage that this would do to the lake for considerable amounts of time after the derby. These lakes hold a select amount of trophy fish and a derby like this encourages people to BONK trophy fish. I'm not a C&R freak but there is really no reason to BONK a fish in Elk Lake, they taste like $hit.
I think I remember reading that they may have some official weigh boats for the derby to support C&R and that is great. Is this the case?
As for the rowers, well that’s a whole other topic...........
Just my thoughts, however I'm open to new opinions on this.
