Flow devices are man-made solutions to beaver-related flooding problems. Flow devices are relatively cost-effective, low-maintenance solutions that regulate the water level of beaver dams and keep culverts open. [1] [2] [3] Traditional solutions have involved the trapping and removal of all the beavers in an area. While this is sometimes ...
Beaver pipes are a non-destructive flow devices, a way of controlling beaver activity in an ecosystem. The process of building beaver pipes is quite simple, and often serves as a permanent way to prevent beavers from damming water.
The flow device, as of 2013, was controlling the water level well. [4] A keystone species, the beaver have transformed Alhambra Creek from a trickle into multiple dams and beaver ponds, which in turn, has led to the return of steelhead trout (Oncorhynchus mykiss) and river otter (Lontra canadensis) in 2008, and mink (Neovison vison) in 2009.
Flow devices, like beaver pipes, are used to manage beaver flooding, while fencing and hardware cloth protect trees and shrubs from beaver damage. If necessary, hand tools, heavy equipment, or explosives are used to remove dams.
One such flow device has been used by both the Canadian and U.S. governments, called "beaver deceivers" or levelers, invented and pioneered by wildlife biologist Skip Lisle. [92] The beaver is a keystone species, increasing biodiversity in its territory through creation of ponds and wetlands. [93]
Backflow prevention device. The simplest, most reliable way to provide backflow prevention is to provide an air gap.An air gap is simply an open vertical space between any device that connects to a plumbing system (like a valve or faucet) and any place where contaminated water can collect or pool.
Resolution included installation of a flow device through the beaver dam so that the pond's water level could not become excessive. Now protected, the beavers have transformed Alhambra Creek from a trickle into multiple dams and beaver ponds, which in turn, led to the return of steelhead trout and river otter in 2008, and mink in 2009.
Benefits of beaver dams include removal of sediment and excessive pollutants travelling downstream, which improves water clarity, which was shown to worsen when beaver dams were recently removed in nearby Taylor Creek and Ward Creek. [25] Flooding from beaver dams is relatively inexpensively controlled with flow devices.
