In July of 2012, I was selected to join Chris Hunt and Kirk Deeter of Trout Unlimited, Rebecca Garlock, Bruce Smithhammer, Steve Zakur, and several representatives of Simms, The National Park Service, and The Yellowstone Park Foundation in a tour of Yellowstone. We were directly involved in removal of the invasive lake trout from Yellowstone Lake, stream study on Soda Butte Creek, and stream recovery on Specimen Creek. This is the second of a six part series recounting my adventures. This was my first trip to Yellowstone.
Okay, how many mornings have you awoke, and over breakfast said to yourself…”yep, today I think I am gonna kill a thousand trout. That is the goal. Not gonna eat em, not gonna sell em, just gonna kill em, cut em, and dump em in the deep water. Then maybe call it a day.”
Lets just settle on agreeing that lake trout aren’t baby seals. Soft fluffy white fur and big watery eyes will trump a cold slimy fish any day of the week, but still…the wholesale slaughter of a trout seems antithetical to the mantra that we catch and release types chant each time we head to the river. We will pass someone who is leaving with a stringer full of trout and we assess them as if they are pariah; an unclean blight on the angling world.
I speak somewhat in jest, but it is honestly a very strange feeling to know that your goal is a mix of trout and death. It just doesn’t roll off the tongue very easily…until you actually do it.
Here is the situation. At some point lake trout arrived in Yellowstone Lake. I say “at some point” because no one is really 100% certain when it happened. Yellowstone Lake is a Cutthroat lake, end of story. The population of this amazing body of water has changed dramatically in recent years, and it has become quite frightening on more than a fishing level. This issue literally effects every creature in the massive Yellowstone that has Cutts as a food source.
Try wrapping your mind around this statistic. In or around 1978, 70,000 Yellowstone Cutthroat Trout were recorded in Clear Creek. In 2008, the number had dwindled to less than 500. You read that right…500. Keep in mind that we are just talking about one creek, God only knows how many feed into Yellowstone Lake. You start running the numbers and it doesn’t take a lot of thought to determine that Yellowstone is in trouble.
Lake Trout live and spawn in Yellowstone Lake, they access no tributaries, they live in deep water, and they eat a bunch of Cutthroat which do access the tributaries to spawn. This leaves only one viable solution. You must get on Yellowstone Lake and kill a bunch of Lakers. Each female Lake Trout is capable of laying thousands of eggs, and with each passing season, these hungry invasives feast on the Cutts.
HOW IT IS DONE
We were blessed with the opportunity to travel out onto Yellowstone Lake and take part in the removal of the Lakers. After a coffee and a danish at the boat dock, we gathered round and Todd Koel gave us the rundown thus far.
When you can tally up 167,703 lake trout caught thus far in 2012, and your work is no where near done…you have got a huge task in front of you.
There are two primary methods that are being used in the eradication process. Gill netting and trap nets, and our merry band of anglers, bloggers, and industry folk embarked on what would become one whale of an adventure.
Gill netting is not pretty. It is a messy, smelly, methodical task that takes a strong constitution and a certain degree of speed to do the job well. So, imagine my surprise when we pulled up to the gill netting boat, and a young blonde coed climbed out and welcomed us aboard. I envisioned a crew of bearded and somewhat scruffy fishermen using foul language, smoking filterless cigarettes and drinking coffee from an old rusty percolator. This boat had two gentlemen who were very polite and soft spoken and a crew of nothing but girls.
With my personal stereotypes completely shattered we put our hands to work. Gill netting was the focus of this boat, and though it wasn’t Deadliest Catch it was pretty intense at first. The best way to describe gill netting would be to envision a massive underwater spiders web. These nets are dropped or “soaked” for several hours and basically the fish entrap themselves within the holes of the net, struggle, tangle, and die. Then comes the dirty work. The net is retrieved and it is the task of the deck hands to extricate the fish from the nets. I knew this was gonna be messy when the captain of the boat handed out blue rubber gloves. Sometimes this involved actually pushing the internal organs of the lakers from one part of their bodies to the other just so they would go through the holes in the nets. This procedure can also cause what the girls on the boat called “poppers”, I won’t go into details, but imagine a balloon that is squeezed just a tad to much. Only this balloon wasn’t full of air….
For ten hours a day, six days a week these co-eds place nets, pull up nets, removed dead fish and repeat, and they actually seemed to be having fun doing it.
So where are all the big lake trout? This particular process is used to remove the smaller fish. On the next post we will take a look at how the big boys meet their maker.
