4.2.4 Other major lagoons – Mosquito and Horseshoe
Mosquito Lagoon (Figure 91) lies upstream of Jewfish along the same secondary anabranch
channel (Figure 4). It is situated adjacent and parallel to the road up the Eight Mile valley,
rather than being immediately affected by a vehicle crossing. Therefore the factors affecting
its water volume are likely to be similar to Jewfish, with again no direct human residence but
with a lesser role played by sediment from road erosion. However since Mosquito has easy
access from the road (Figure 4), it is likely visited more frequently by travellers and tourists
than Jewfish or Oriners. This fact makes factors like weed invasion and overfishing more
significant. In addition, it is a major location for water withdrawal for road construction crews
