With the sun now shining at Brooklands, Five Rivers Environmental Contracting Ltd have brought out the big guns!
Visitors to the park in Worthing may have noticed the new amphibious excavators operating in the lake.
With all the rain this winter moving the silt off the lake bed has been difficult.
But the advanced piece of kit means the contractors can continue working even with increased water levels. Previously in times of very high tides work on the lake would have needed to come to a halt.
