We put together a web map that shows where some of these wildlife crossing structures are located within Utah.
Jessen and Tamarack lakes have numerous tiger trout larger than our 18-inch measuring board, yet these fish have two or three summers of lifespan left! The fat content on these fish is outstanding. These fish are flat-out impressive!
Instead, I’ll simply say that the procedure is a lot of fun – a lot. Much like birdwatching in the wetlands, you can detect a capture operation by attentive observation. A long train of DWR trucks with trailers in tow can be spotted slowly driving along dikes in the wetlands.
Wipers were introduced to Newcastle Reservoir in 2005, and by 2009 golden shiners had almost completely disappeared. Rainbow trout and smallmouth bass immediately started showing improvements and now they provide outstanding fishing opportunities.
Artificial nesting boxes have been used by people all across the county to provide nesting habitat for wood ducks. Nesting boxes have also proven to be very successful in Utah.
We then place the eggs into a specially designed sieve that goes into a hydraulic pressure chamber. This chamber subjects the eggs to 9,500 PSI of pressure for ten minutes. This pressurization step is what makes the fish sterile.
Another part of the work (the part that I’ve been working on) involves catching adult pelicans and attaching GPS transmitters to track daily and seasonal movement patterns.
Holders are charged with the toughest part. They are tasked with securing the birds so the banders can install a leg band on the left leg and patagial markers on each wing. Not as easy as it sounds, when you consider that they have to hold the 15-pound bird securely. They also have to hold the pelican’s bill so it can’t bite anyone.
No matter where you live in Utah, there’s upland game nearby. You can hunt in the Mojave Desert for quail, the alpine habitats of the Uinta Mountains for ptarmigan, the agriculture fields for pheasants, the beautiful yellow and red grandeur of the Wasatch Front for ruffed grouse. Diversity is the spice of life.
The use of guzzlers provides water to all types of wildlife in areas where water sources are few and far between. One of the great benefits of this is the ability to attract animals to areas with abundant forage and little natural water…
As a biologist and angler who spends a lot of time on the reservoir, I have received reports and witnessed kokanee mortalities on the surface of the reservoir during the summer months. Sometimes there are so many dead fish, they look like bread crumbs trailing behind trolling boats.
The crew put up screen troughs on the tree trunks below the bark, which they refer to as poop-catchers.
