Abstract
A structure for diverting fish away from water intakes comprises a porous dike having a bottom portion, a central portion, and a top portion, the top portion preferably being submerged a short distance below the surface, and the central portion having flow passages. In a preferred embodiment, the top and bottom portions comprise solid blocks and the flow passages in the central portion are lined with zebra mussel resistant sleeves to minimize clogging. Preferably the sleeve can be readily replaced as desired.
Claims15
A structure for diverting fish in a body of water away from at least one water intake comprising:
- a porous dike formed by a plurality of blocks having a bottom portion, a central portion, and a top portion,
- the central portion having a plurality of elongated flow passages, and comprising openings large enough to permit a flow of water through the dike and large enough that fish can pass through the passages, but said flow passages being sufficiently confined spaces but to present an aversion to fish, so that fish avoid passing through the passages.
A structure for diverting fish away from at least one water intake comprising:
- a porous dike having a bottom portion, a central portion, and a top portion,
- the central portion having flow passages comprising openings large enough to permit a flow of water through the dike but small enough to present an aversion to fish,
- wherein each of said flow passages is lined with at least one sleeve.
The structure of any one of the preceding claims, wherein at least one of said flow passages comprises a pipe.
A structure for diverting fish away from at least one water intake comprising:
- a porous dike formed by a plurality of blocks having a bottom portion, a central portion and a top portion, at least one of the portions having a plurality of elongated flow passages therethrough comprising openings large enough to permit a ready flow of water through the dike, but small enough to present an aversion to fish due to perception rather than actual physical limitations.
