Fish population decreases due to loss down irrigation systems

[monger]

Today's trout populations are under increasing pressure due to low flows, increased angler numbers and the significantly large losses which happen yearly with the unscreened removal of irrigation water from a variety of southern Alberta rivers. Amongst the trout losses, we are seeing both SARA listed species of Bull trout and Cutthroat trout being siphoned out of southern rivers. This loss of these threatened species should be ringing Federal alarm bells and have a response from the DFO. The Alberta government has identified this ENTRAINMENT of fish in irrigation systems as a major factor in the decline of trout in the Bow river. It would make sense that this concern should be applied to all the southern rivers where irrigation water is drawn off. The problem is that the irrigation districts are not adequately screening (if at all) the water they are removing from the rivers. When water licences are issued, there would be a requirement to limit fish loss through some type of sceening/deflection system. I believe it is up to the AER to monitor and inspect these screening systems to ensure they are performing adequately to decrease fish losses from the river. At present, there seems to be little, if any, enforcement in this regard.

As we continue to see river trout populations struggle, it will be up to the voice of concerned citizens to get the government's attention. The irrigation districts have a very strong voice with the AB government which allows them to receive many favors, especially lots of funding, for the ongoing expansion and modernization the growing irrigation network. Many believe it is time for citizens who are concerned about fish populations being detrimentally impacted by irrigation entrainment to speak up. Anglers of all types are impacted by the loss of fish being siphoned out of the river. A strong, organized voice is required to get the government's attention to take some action. This issue was identified more than 100 years ago when the first irrigation systems were put in place. It is far past time the government start to act to decrease the losses of fish populations down a ditch.

A collection of folks has started a group to raise a concentrated voice to the government. If you are concerned or interested about trout populations, seek out The Trout Trust

It will take a number of voices to make some noise to get the government to act.
