ABSTRACT:
A flexible impermeable cover for a reservoir which completely covers the fluid in the reservoir and facilitates the removal of surface rainwater to a defined peripheral sump immediately adjacent and completely surrounding a central floating cover portion. Float means are attached to at least substantially the entire border area of the central portion and weight means are affixed to the cover outwardly of the central portion and adjacent the float means in substantially all of the border area so as to tension all of the central portion. The weight means also create a defined peripheral sump outwardly and immediately adjacent the entire border area of the central portion which collects the surface rainwater from the central portion.
