LA is dumping millions of plastic balls into its reservoir to tackle the drought

Will tarp be a single piece or multiple pieces? What's the weight of the tarp? how do you make sure it's on the surface? Or do you need a support structure to keep it above the surface (say a meter etc.)? Will it have holes to drain? Will holes be sturdy enough in the long run? etc...

I was thinking why they use ball form instead of something sheet-like. E.g. thin pancake - it will have same properties as the balls but will cover surface more efficiently, if you count material.
