Water Quality In Narrabeen Lake?

[kbark]

Does anyone know if there has been any recent work done on the water quality of the lake and also on the toxin levels in the various species? I catch and release most of my fish but take home a feed every couple of weeks.

council (warringah or pittwater - not sure) commissioned a WQ study, done in 2000, i think (a friend worked on it). as far as "toxins" go - it doesnt have the heavy industrial activity that the harbour used to have so it is relatively clean, for a big city waterway

I've found a few websites that mention recent studies and the ones I've looked at suggest that the water quality is ok for boating but poor for swimming. It seems the bacteria levels from stormwater and sewerage contamination are a problem from time to time. You'd think that if there was a problem the council could at least let us know. The accumulation of toxins over time in the fish population is another question, esp with the lake entrance closed for such a long period of time. No one here knows anything specific???

high bacteria (pathogens to be exact) levels due to poo are a problem in every waterway in syd with an urban catchment, mainly after rain. these are killed after a few days of sunlight.

i would think it is EPA's responsibility for warnings? after all they do the beachwatch reports.
