The Sunshine Coast Council will temporarily close the entrance to Currimundi Creek from next week in a bid to reduce the biting midge menace.
Division Three Councillor Keryn Jones said about 5000 cubic metres of sand will be moved from the sides of the creek mouth to temporarily close Currimundi Lake.
“The lake’s closure, which Council undertakes every year or so, floods the biting midge habitat and subsequently reducing the adult midge population,” Cr Jones said.
“Plugging the lake is timed to coincide with peak midge activity so that we can disrupt the breeding cycle as much as possible.
Cr Jones said the environmental impact from closing the lake is expected to be very low but the situation will be closely monitored by Council staff.
“The lake will remain open for swimming and Council officers will monitor the water quality very closely,’’ Cr Jones said.
The work will be carried out by local contractors and Council officers, with the movement of the sand timed to coincide with a lower than average tidal range. Council aims to start work on August 27.
The entrance would remain closed, weather permitting, for between four and six weeks.
“That will be determined by a few factors, with our officers closely monitoring midge activity and water levels during the closure,’’ Cr Jones said.
“We’ve consulted with our community on this and I know many residents are pleased to see our Biting Midge Control Program address the problem.
"I share concerns of some community members that closing the entrance may worsen upstream erosion and subsequent siltation, but the coastal engineer assures me that the impact will be minor.
“The estuarine nature of the Currimundi system means that a certain amount of midge activity is a fact of life. However, this step aims to reduce their numbers to a more bearable level for residents and visitors with the least environmental impact."
