Shallow Water Fish Screen
Dateline: December 2025 - Prototype - 3 Inch Fish Screen  -
Designed to work in less than 11 Inches (280mm) of water. 

Solid base prevents organism disturbance in the bottom substrate.

Swivelling 3 Inch intake on top with four hard eyes for lifting

Perfect for all pumping operations using surface style pumps with an intake of 25.5 liters per second ( 356 US Gallons per minute) or less.  This Fish Screen can be suspended beneath a surface float or simply sit flat on the bottom. It is designed to operate in less than 11 inches (280mm) of water if required. The unique design has a swiveling 3 inch quick disconnect intake on the top side for ease of connecting your pump's intake hose.
We have adapters in stock to convert this three inch unit to work with a two inch  pump.  As with all of our individually serial numbered Fish Screens, it comes with a laminated "Certificate of Compliance" to make environmental inspections a breeze.

 Fish Screen for pumping water through an 8 inch augured hole in the ice

New version introduced December 2025

When flooding ice roads or supplying water for temporary camps, water is pumped from convenient sources found under ice that may be fish bearing. Back in 2011, the Department of Fisheries and Oceans collaborated with stakeholders to come up with a design criteria for  suitable fish screens that reduce the risk potential of injury or death to fish during the water extraction process and is a requirement under Section 30 of the Fisheries Act.  Accordingly, the lower risk potential to fish is based on the use of temporary water sources and the limited duration and frequency of water withdrawals at these sources; As well, the operational challenges were factors in the selection of the basket screen design.

Shallow Water Fish Screens

A northern mine asked us to design and fabricate four fish screens for their pumps to operate in relatively shallow creeks. To maintain compliance with the Department of Fisheries and Oceans regulations, the "approach velocity" from the underside of the screen has to be low enough to not disturb any organisms living in the creek bottom substrate while simultaneously ensuring that the peripheral approach velocity would allow a fry size fish of the weakest swimming species of fish found in the water being pumped to not be impinged on the screen during operations. 

For enhanced low flow, the manifold holes have nearly three times the open area of the the manifold intake opening. As well, the placement of the graduated holes helps ensure a more consistent even flow across the screen.

A Universal Fish Screen for Multiple Sizes of Water Pumps

  A construction company client uses three different sizes and capacity of pumps, but did not want to purchase three separate fish screens. To solve this issue we designed a fish screen with an effective screen area that is compatible with the the flow capacity of the largest pump in his inventory, then found a source for cam-lock adapters that allows the use of the other two pump sizes with the same fish screen.
