Abstract
A system to exclude trash from curbside drains during periods of no or slow water flow, but opening to permit full entry during heavier flow such as during heavy rains. The system may have a linkage preventing opening by force on its barrier, and to assure that it will remain open should downstream drainage systems become flooded.
