On February 29th, the Building Multi-Year Drought Resiliency Workshop was hosted by four southern Watershed Planning and Advisory Councils (WPACs): Oldman Watershed Council, South East Alberta Watershed Alliance, Milk River Watershed Council Canada, and Bow River Basin Council.
The fifth instalment in our "Understanding Drought" blog series is now live. In it, we look beneath the surface and unearth information about groundwater.
Blog #4 in our *Understanding Drought** blog series about the current drought in Alberta. Learn about how Alberta’s water-using sectors have made improvements to water conservation, efficiency, and productivity.
In blog #3 in our “Understanding Drought” series, we look at water management, sharing, and licensing in Alberta.
As we pause between Christmas and the new year, many of us finally have the time to count our blessings and think about what gifts we have been given that may not have come from Santa's sled. Fix a hot chocolate and curl up with an article from OWC volunteer and Guest Blogger, Ted Naninga. He's a wildlife biologist, and new to the Lethbridge area. He explains why the Oldman watershed is the greatest gift of all. We agree! There are still two days left in 2016 if you'd like to donate. https://oldmanwatershed-council.squarespace.com/donating
Book The Date JULY 26th! Learn about the science and history of Waterton Lakes National Parks... topics include the threats facing salamanders, cross-boundary work on climate change, the parks’ lesser-known past and how remote cameras are used to track wildlife movement. Experts will discuss aquatic resources, landscapes, history and wildlife.
Editor's Note: Thanks again to wildlife photographer Rick Andrews for this guest blog postwith his stunning images! I had the privilege of having lunch with Rick recently. Our conversation quickly turned to our mutual love of the watershed - and well ... kids these days. Specifically, our own! How, we wonder, can the watershed be protected for future generations when many kids aren't given the opportunity to be out there, without electronics and understand what it means to slow down to Nature's pace - in order to be actually take notice and cherish the little things that need protection?
Pelicans and Garter Snakes text and images by Rick Andrews
The sound of a wing slap on the water startles me and I look up from my camera’s LCD screen just in time to get splashed in the face. The guilty culprits, about a dozen American White Pelicans are quickly swimming away while glancing back over their shoulders like mischievous children wanting to be chased. While I usually allow wildlife to establish their own comfort zone by approaching me, I wonder if they’re telling me I’m perhaps a bit too close, so I back up and give them a little more room, just in case.
I’m spending the morning down at the weir photographing some of my favorite wildlife subjects. People often assume that to photograph wildlife you need to go “somewhere,” but here in Lethbridge we’re fortunate, we don’t have to go anywhere, wildlife is all around us.
The weir is a small dam built by the city to create a deeper body of water, making it easier to divert river water into the water treatment plant. But like a lot of dams that have no fish ladders to aid fish swimming upstream, it traps thousands of minnows that are now easy pickings for hungry predators.
I watch the pelicans as they swim back to the edge of the weir driving the minnows into deeper water where they readily scoop them up. Yesterday I watched from the other side of the river as a group of pelicans drove minnows into shallow water. Then turning their heads and bills sideways, they scooped up the minnows with their bill pouches. Clever birds these pelicans.
But pelicans are not the only hunters here today - there are others that are neither bird nor mammal. Reptiles have come to feed on the minnows too, and the pelicans are unwittingly helping them by driving some of the minnows into the shallows.
Wandering garter snakes, a subspecies of the western terrestrial garter snake, are very skilled swimmers and hunters, and I watch as they slip silently into the water. In the shallows I can see them darting about, and it doesn’t take long before they return with a fish in their mouths.
Given their numbers today, I wonder if I’m not sitting on top of their hibernaculum, especially when I see them climb back up the river bank before disappearing into its numerous cracks and crevices all around me.
A sure sign of a healthy ecosystem!
A few days later I return, this time bringing local naturalist and snake expert Ken Moore with me. Ken tells me that wandering garter snakes can be found throughout the Oldman River valley, and though they are the least common of Alberta’s three species of garter snakes, in Lethbridge they are the most common. But its a very hot day, perhaps too hot for reptiles, and so we see only one. But that could also have something do with the red-tailed hawk we just saw sitting in a nearby tree as we approached. Along with other raptors such as osprey and owls, herons, weasels, raccoons, foxes and coyotes are all known to prey upon garter snakes too, but today its the garter snake that is the predator.
Snakes smell and hear ... like us ... only they smell through their tongues and have no ears!
I also learn that on land it finds its prey by smell together with a chemical sensory system known as the Jacobson's organ. During this process garter snakes flick their tongues, sweeping the air for scent molecules, before inserting their now scent enriched tongue tip into two tiny pits in the roof of its mouth. Once their prey species has been located, the actual attack happens very quickly.
Ken also tells me it’s doubtful this is their hibernaculum as its most likely located at least halfway up the coulee - well above the waterline. Besides, their hibernaculum is where they typically den during the winter months, then after mating in the spring, they head out, sometimes traveling as far as 25 km to spend their summers alone. Adults can grow to about a meter in length, but the one we see today is much smaller, so its perhaps a juvenile or maybe a young adult male.
Out on the water, the pelicans continue to feed and are soon joined by others that have been spending their day fishing elsewhere up river. But its getting really hot now and after making its way back up the riverbank, our garter snake disappears into one of the many crevices to cool off. Taking a cue from this little wanderer, we too wander back up the coulee before heading over to Tim’s for a little air-conditioned comfort and a nice cold Iced Capp.
Ya gotta love summer in Lethbridge.

Over the past several years I've photographed wildlife in many locations throughout the Canadian and US Rockies, as well as remote locations such as Nome Alaska and Hokkaido Japan. Along the way I've met many wildlife photographers from those just starting out to seasoned veterans. In fact since the introduction of digital cameras, wildlife photography has never been as popular as it is today, so if you are one of those people who share my passion, here are a few tips to help improve your wildlife photography and keep you safe while doing it.
