The system also includes a generator that generates electric power from the body of water, and one or more electrodes that induce an electrocoagulation current upstream of the dam. A filter press then removes contaminants that are precipitated from the water of the body of water by the electrocoagulation current. ## Claims ### Claim 1 A system for cleaning contaminants from a body of water, comprising: a dam configured to restrict a flow of water in the body of water; a generator configured to generate electric power from the body of water; one or more electrodes configured to induce an electrocoagulation current upstream of the dam; and a filter press configured to remove contaminants that are precipitated from the water of the body of water by the electrocoagulation current. ### Claim 2 (depends on 1) The system according to claim 1, wherein the dam includes at least two I-beams configured to be driven into a bottom of the body of water, and at least one concrete slab disposed between the at least two I-beams. ### Claim 3 (depends on 2) The system according to claim 2, wherein the concrete slab is reinforced with at least one of rebar and fiberglass. ### Claim 4 (depends on 2) The system according to claim 2, where in the at least one concrete slab includes at least one opening to allow a predetermined flow of water from an upstream side of the dam to a downstream side of the dam. ### Claim 5 (depends on 1) The system according to claim 1, wherein the generator is disposed upstream of the dam. ### Claim 6 (depends on 1) The system according to claim 1, further comprising at least one hoist to lower the one or more electrodes into the body of water upstream of the dam. ### Claim 7 (depends on 1) The system according to claim 1, wherein the filter press includes a suction member configured to draw a combination of water and contaminants into the filter press. ### Claim 8 (depends on 7) The system according to claim 7, wherein the suction member includes a hose configured to be lowered into a sludge collection zone established at a bottom of the body of water. ### Claim 9 (depends on 1) The system according to claim 1, further comprising a boom configured to contain contaminants at a surface of the body of water, the boom being deployed upstream of the dam. ### Claim 10 (depends on 9) The system according to claim 9, wherein the boom is formed of foam. ### Claim 11 (depends on 9) The system according to claim 9, wherein the boom is inflatable. ### Claim 12 (depends on 9) The system according to claim 9, further comprising a weir configured to remove the contaminants contained by the boom. ### Claim 13 A method of cleaning contaminants from a body of water, comprising: restricting, with a dam, a flow of water at a predetermined location of the body of water; generating, with a generator, electric power from the body of water; generating, with one or more electrodes, an electrocoagulation current upstream of the dam; and removing, with a filter press, contaminants that are precipitated from the water of the body of water by the electrocoagulation current. ### Claim 14 (depends on 13) The method according to claim 13, further comprising: driving at least two I-beams into a bottom of the body of water; and installing a concrete slab between the two I-beams in order to form the dam. ### Claim 15 (depends on 13) The method according to claim 13, further comprising: digging a sludge settling zone at a bottom of the body of water, the sludge settling zone being configured to capture contaminants as the contaminants precipitate out of the water, the sludge settling zone being upstream of the dam. ### Claim 16 (depends on 15) The method according to claim 15, further comprising: suctioning water including the contaminants captured in the sludge settling zone; and providing the water including the contaminants to the filter press. ### Claim 17 (depends on 16) The method according to claim 16, further comprising separating the water from the contaminants at the filter press. ### Claim 18 (depends on 13) The method according to claim 13, further comprising: containing, with a boom, contaminants on a surface of the body of water, the boom being disposed upstream of the dam. ### Claim 19 (depends on 18) The method according to claim 18, further comprising: removing, with a weir, the contaminants contained by the boom. ### Claim 20 (depends on 13) The method according to claim 13, further comprising storing, at least temporarily, the electric power generated by the generator in one or more batteries.
