It looks like its right off an inlet to Toondah Harbor so it can very well be saltwater or at least brackish
For those of you interested in the Sharks - they came in to the lake in 1996 after a massive flood in the area and the rivers nearby burst their banks. Since then we believe they have reproduced and there are up to approximately 12 sharks in the lake now. The lake is approx 90,000 m2 in size and up to 15 metres in depth. There are a heap of fish species and obviously enough to keep the sharks well fed.

'Blood In The Water' is a movie about the series of shark attacks at New Jersey beaches in 1916, the scene of the first multiple shark attacks in U. S. history, including one in a creek -- Matawan Creek.
Based on a true story. it recounts the 12-day period in 1916 where five people were attacked by sharks.
Although many believed that the shark that killed the two at Matawan Creek was a Great White shark, there are others who believe it was a bull shark. Bull sharks have been found in various fresh water sources, sometimes far upriver or upstream in some cases, their high tolerance for fresh water nearly unique among shark species.

Ichthyologist Thomas Thorson studied bull sharks living in Lake Nicaragua and found these huge fish take in a lot of extra water, as expected, but they excrete much of it as dilute urine, at a rate of over 20 times that of typical saltwater sharks. That means their kidneys must work extra hard, utilizing additional energy. Like people who become accustomed to life in low oxygen regions, however, sharks in fresh water appear to adapt to what would seem to be formidable conditions.
Although a survey of freshwater sharks and rays in 1995 determined that 43 species of elasmobranches penetrate freshwater environments, relatively few sharks spend substantial time in these areas. Sharks that do frequent such regions include the river sharks and the aforementioned bull sharks.
