1. An artificial floating lake system for recreational purposes comprising:
- a. a floating lake having a surface area larger than 5,000 m2 and installed within a larger water body selected from an ocean, river, lake, reservoir, lagoon, pond, canal, estuary, stream, ocean bay, river bay, dam, pond, harbor, and bay, the floating lake comprising a flexible bottom having a Young'"'"'s modulus of less than about 20 GPa and walls having a rim, wherein the rim comprises a flotation system;
b. a chemical application system for applying an oxidant or flocculant to the water in the floating lake;
wherein the chemical application system is activated to apply an oxidant to water in the floating lake to establish an oxidation-reduction potential (ORP) in the water of at least 550 mV for about 10 to about 20 hours within a 52-hour cycle;
c. a pumping system for supplying replacement water to the floating lake to maintain a positive pressure against an inner surface of the walls and bottom of the floating lake, wherein the positive pressure is at least 20 Newtons per square meter of the surface area of the floating lake, wherein the positive pressure is maintained for at least 50% of the time within 7-day intervals, and wherein the replacement water has a true color of up to 35 Pt—
Co and less than 2,000 CFU/ml of bacterial count;
d. a mobile suctioning device capable of moving along the flexible bottom of the floating lake and suctioning a portion of water from the bottom containing settled solids, wherein the mobile suctioning device is configured to be activated before a black component of the bottom of the floating lake exceeds 30% on a CMYK scale, wherein the CMYK scale denotes a Cyan, Magenta, Yellow and Black color scale;
e. a filtration system in fluid communication with the mobile suctioning system, wherein the filtration system receives the portion of water suctioned by the mobile suction system; and
f. a return line for returning filtered water from the filtration system to the floating lake.

Abstract
The present invention relates to floating lakes and to the treatment of the water in such lakes. The present invention further relates to large floating lakes that can be installed within a natural or artificial water body to improve water conditions that are unsuitable for recreational uses. The floating lake can be provided with a chemical application system; a filtration system including a mobile suctioning device and filters; a skimmer system, and optionally a coordination system.
