# Reservoir

An artificial or natural water body used to store water for municipal supply, irrigation, industrial cooling, process water, or flood-management purposes.

A **reservoir** is an artificial or natural water body used to store water for municipal supply,
irrigation, industrial cooling, process water, or flood-management purposes. Industrial reservoirs
— including potable service reservoirs, tailings storage facilities, irrigation reservoirs,
cooling ponds, and fire-suppression storage — are the primary deployment context for floating
covers, where covers reduce evaporative loss, algae growth, odor release, and heat loss.
