Vertical slot fishways The basic design of a vertical slot fishway is a rectangular channel partitioned by baffles into resting pools. When the water is flowing the fish swim from pool to pool through vertical slots that are orientated vertically. The advantage of this design is that passage is possible at a variety of water levels (Plate 21 ... New designs for vertical slot fishways - CORE New designs for vertical slot fishways . By N Rajaratnam, C Katopodis and S Solanki. Topics: design, hydraulic design, hydraulics, open channel flow, pool, turbulent flow ... Implications of Fish Behavior for Vertical Slot Fishways ...
"New Designs for Vertical Slot Fishways" by N Rajaratnam, C Katopodis et al.
Moreover, there is limited technical information on the relative cost and designs needed to provide passage above current barriers for such species as walleye, sturgeon, and white bass while minimizing sea lamprey access to these same areas … Microsoft Word - IAHR Schedule.docx shallow flow model for flood Yusof Administration However, for the purposes of these rules, the Columbia River Estuary extends to the western edge of Puget Island. (16) "Exclusion barrier" means a structure placed that prevents fish passage for the benefit of native migratory fish. Microsoft Word - final 9-21-06 minutes.doc Kosmo Ken Bates report Kosmo Ken Bates presented his analysis of four different fish passage options for the BART weir, including two vertical slot fishways (one for the weir and one for the weir and the inflatable dam), the roughened …
The performance of two particular designs of vertical slot fishways for two different slopes was studied in a wide range of discharges. Water depths were measured in almost the whole surface of pools.
An effective vertical slot fishway must allow fish to enter, pass through, and exit safely with minimum cost to the fish in terms of time and energy.In order to address this deficit, it should be required to complete the fishway design methodology with results from experimental assays with living fish.

"Suitability of Vertical Slot and Denil Fishways for… A vertical slot fishway and two Denil fishways (of 10 and 20% slope) built into a weir on the Lesser Slave River (55º18'N, 115º45'W) were studied from May 12 to June 25, 1984, to determine how effectively these designs pass north-temperate, nonsalmonid fishes. Thousands of spottail shiner... Fishways at the River Murray barrages - Department of… Existing vertical slot fishway at the Tauwitchere Barrage. Fishways, also known as fish ladders, are structures that allow fish to navigate through obstacles in rivers and creeks. At the River Murray Barrages, new fishways will be constructed to help 30 native fish species complete their natural...
A vertical slot fishway and two Denil fishways (of 10 and 20% slope) built into a weir on the Lesser Slave River (55°18′N, 115°45′W) were studied from May 12 to June 25, 1984, to determine how effectively these designs pass north-temperate, nonsalmonid fishes.
Fishways - NSW Department of Primary Industries Pool-type fishway (includes vertical slot fishway) Pool-type fishways were the first type to be developed and consist of a series of interconnected pools bypassing an obstruction. Many different types of pool fishways have been designed in Australia, however, the vertical-slot design is the only one which has proved effective with native fish.
