 Prior to refurbishment in the mid-1990s Lake Guthridge suffered a blue-green algae problem that resulted in widespread fish mortality until local joggers and nearby residents complained of the associated stench causing council to act.Lake Guthridge has never been used as a food source.A significantly superior natural waterway of historical significance is the aforementioned Port of Sale (previously "Sale Canal"), the original inspiration for the early town's original name - "Flooding Creek".
