A lucky break for us. Regardless, I think we have well in excess of 100 street drains entering the Bay along the East side alone. This is a scandal, although one council (Kingston) is now providing simple pre- treatments. All such drains should be re-directed or pre-treated. We emphasise the drains problem graphically in our new Marine Education Centre at Rickets Point.
