What is the best way to keep turbidity low?
The best way is to have functioning Riparian Zones because they stop air borne debris from getting into the lake.

When it rains, the Riparian Zone will try and filter these particles to prevent them getting into the water.
First team with their hand up. 1 chance. Once your hand goes up 3 seconds to answer MIGHT NEED CALCULATOR AND PAPER?
How much water does Mr. Gearside's food need to be made for the week?
Mr. Gearside's mum makes him 4 chicken tender sandwiches a week, each containing two tenders on white bread.
Mr. Gearside's girlfriend makes him 2 vegemite sandwiches on wholemeal.
Mr. Gearside makes himself a mashed potato sandwich on wholemeal which sogs in his bag all day.
Chicken tenders take 4000L per tender. Vegemite 1 serve 500L Wholemeal bread 2 slices = 1500L Mashed potato = 2000L white bread 2 slices = 600L
Chicken Tenders 8 x 4000L = 32 000
White bread 4 x 600L = 2400
Vegemite 2 x 500L = 1000
Wholemeal 2 x 1500L = 3000
Mashed potato = 2000
Wholemeal = 1500
ANSWER = 41 900
