Type 2 turbidity curtains are most often found in larger lakes, intercoastal areas, and other waterways with mild waves, currents, or wind. Like their other Type counterparts, these curtains can be completely PVC, completely impermeable to water and solids. Or, they can include a filtering window that allows some water to pass through. These curtains are more durable than Type 1 curtains, but aren't quite as heavy-duty as Type 3.
A Type 2 DOT curtain has been built to specifics required by Department of Transportation regulations, including considerations for the strength and durability of the fabric itself. They can be found in standard turbidity curtain sizes, reaching up to 100 feet deep. You'll most often find these in places with moving water, but without the rougher and faster conditions found near or around oceans.
