Adsactly Education - Snake River
It’s possibly one of the biggest rivers you’ve never heard of. Like all the rivers of the western US it is at risk in some ways, but probably the least at risk of them all.
The Snake is the largest tributary of the Columbia River system. It probably got it’s name from early Europeans who took the Shoshone hand sign as meaning Snake when it was actually ‘river with many fish’. A simple mistake that stuck.
It’s Due Course
The Snake starts on the same plateau in Wyoming that the Missouri starts in. The Missouri flows east, and the Snake west. It flows into Jackson Lake and then into Jackson Hole, a break in the Grand Teton Mountains. From there it flows south and west over the Snake River Plain, a huge area that is over an enormous aquifer that provides clear drinking and irrigation water to hundreds of thousands of acres. The french fries you eat today have a great chance of being from potatoes grown with water from the Snake River or from the Snake River Aquifer.
Once the Snake has passed all the way through the state of Idaho it turns north and becomes the boundary between Oregon and Idaho and later between Washington and Idaho. The boundary between Oregon and Idaho is home to the legendary ‘Hell’s Canyon’ said by many to be the deepest in North America. Much of the lower Snake is in a monstrous canyon that was carved by a flood something less than fifty thousand years ago. It joins the Columbia in the Tri-Cities Washington. The Snake flows a total of 1,078 miles (1,735 km) and becomes part of the largest river to dump water into the Pacific Ocean from North America.
The Snake flows an average at the Tri Cities of near 55,000 Cubic Feet Per Second and can flow as much as 400,000 CFS in flood season. That makes it roughly three times the size of the Colorado.
What Makes It Important?
The Snake is an incredibly important Salmon and Steelhead trout fishery. More than a million salmon run up the Snake to spawn. It is estimated that the Salmon runs are worth in excess of 50 million dollars per year to Idaho, a landlocked state. The net worth of these salmon runs is hard to calculate because so many are taken in the Pacific Ocean, but the total value is over 500 million per year.
The four dams on the river from Hell’s Canyon to the mouth produce a huge quantity of clean, renewable energy. 65% of the power produced in the Pacific Northwest is hydroelectric and the Snake certainly plays it’s part.
The Snake is also part of a huge tug and barge network with the Columbia. Much of the wheat produced in Idaho, Oregon and Washington is transported to the Pacific ports in barges. Lewiston Idaho is a major shipping point for grain and paper made from trees in northwest forests.

Recreation is another huge revenue generation machine on the Snake. Fishing and watersports are very popular through the whole drainage. Tourism is also very popular not the least of which is the Hell’s Canyon area. You can take a jet boat up the river and then raft down if you are so inclined. Pretty exciting place.
Geology of the Snake
Right at the start, the Snake trickles out of the west slope of the Rocky Mountains and all the igneous rock that is to be found there. The real geology of the river is all about volcanic flows.
At least three massive volcanic events in the last 150 million years have basically shaped the entire drainage of the Snake River. Massive basalt deposits just waited until the force of water began to carve the canyons. At the end of the last ice age (about 14,000 years ago) the area of the Great Salt Lake was a massive inland sea that escaped rapidly, leaving no choice but to carve out the rock as the water rushed to the ocean. Sometime later an even larger body of water known as ‘Lake Missoula’ drained even faster leading to the basic form of the river we see today.
Local indigenous legend remembers the great flood. It is entirely possible that there were inhabitants in the region between the Rocky and Cascade mountains. The flooding would have been catastrophic and only pockets of people and animals would have survived. Certainly there were people nearer the coast when the floods came.
Native Populations
By 11,000 years ago relatives of today’s indigenous populations were living and thriving in the Snake River drainage. Millions of Salmon and Steelhead spawned as far upriver as Shoshone Falls (near modern day Twin Falls Idaho). A large number of mostly affiliated tribes called the region home.
Millions of fish, deer, bear, and elk gave the natives adequate protein and a good many edible roots and berries made for a balanced diet. A range of mountains to the east and the west plus the rivers themselves gave the population relative peace and calm to settle into a long term history on much of the land in the Snake River drainage.
There are several historic trading sites in the Snake River drainage that date back thousands of years. The purpose and execution of these sites are murky at best, but varied peoples were using some of them at least 10,000 years ago. Horses came into the area (and nobody is quite sure how) during the 1700s. They certainly changed the lives and livelihoods of several of the tribes.
European Interaction
There is no doubt that there were some trappers and explorers in the area earlier, but the written history of the Snake begins with the Lewis and Clark expedition at the very start of the 19th Century. When the US completed the Louisiana Purchase then President Jefferson decided it was time for an official party to journey to the Pacific Ocean. The first tributary of the Snake that the party saw was the Salmon River in present day Idaho, though they found it too violent to use for transport. They originally named the river the Lewis River (or Lewis Fork) but the name didn’t stick.
Lewis and Clark generally treated the local inhabitants well, and were in turn treated well by them. It wasn’t until more and more settlers started to arrive in the basin that hostilities began. Some of the last and most famous of the Indian Wars were fought in this part of the world.
Europeans started large scale farming in the Snake River Basin and the practice goes on to this day. Many of the earliest settlers came to the area on the ‘Oregon Trail’, the most famous of the transcontinental trails. Much of the original trail follows the Snake or one of it’s tributaries. One of the most famous sections runs up the Brule River canyon from a crossing of the Snake at present day Ontario Oregon. It was the last really brutal climb and stretch of the trail and a great many died making it.
The State of the River Today
The Snake River is generally healthy and robust. It is not under huge threat from pollution or contamination. Agricultural runoff has caused some problems but are being addressed with improved farming practices. Except for the dams.
There are 15 dams on the Snake. The lower four dams on the Snake are controversial at best. All four were installed to generate electricity, improve flood control and facilitate deep water navigation. The four compromise the Lower Snake River Project and were built and maintained by the US Army Corps of Engineers.
There is no question that the dams harm the Salmon and Steelhead runs on the Snake. The four dams create a series of impoundments with no free flowing stretches of river between. There are current proposals on the table to remove all four.
Advocates for the removal cite the Salmon Runs as their principal concern. There is no doubt that the dams raise the water temperature of the river and kill millions of fry on their way to the sea. They also indirectly give predators a greater chance to eat the little fish. Conservative estimates figure the runs could at least double just by removing the dams. It is predicted that 2x runs could provide Idaho with an additional 90 million dollars per year just off the fishing. The numbers would go way up for Washington and Oregon as well, and the various tribes would be able to take their treaty granted quantities of fish. Not to mention the improved fishery over the whole North Pacific.
A secondary result would be a return to the natural state of the Hell’s Canyon, one of the most spectacular water courses in the world with it’s improved tourism.
Opponents of removal cite the possibility of catastrophic floods, loss of navigation to Lewiston Idaho, loss of the cheap and clean hydroelectric power and the stunning cost of removal.
Both sides are right, and both sides are wrong. It will be interesting to see where the controversy ends..

I drive by that barge terminal all the time. It’s about 1/2 -3/4 of a mile before the Snake river pours into the Mighty Columbia River.
Most think of Washington state as a very woodsy and rainy place. It’s far from that. The east side is desert and these rivers and dams are what keep the farming alive and well on the eastern side of the state. Barges are constantly carrying grain from the eastern side of the state to the Pacific Ocean, through all dams on be Columbia and Snake rivers. To be distributed all over the world.
I was in my brother's boat when I took that picture! He lives in Kennewick. I was there for 10 days with a bit of a mechanical problem. I grew up on a farm straight north of there. We sent a lot of wheat down the river for a fact.
No kidding, what a small world. I grew up in Kennewick and lived in the waters of the Columbia and Snake Rivers during the summer time. Evening out on the family boat, man I miss those days.
Oh and the island to the east of where you took that picture. Strawberry island great little spot with some sandy beaches
That’s true! Actually I’ve already read about that river in your recent post, so I’m a bit familiar thanks to you. When you mentioned french fries, first thing popping in my head was “Idaho potatoes”. Reading further it confirmed my suspicion. I mean what else it should be “a couch potato”lol? Luckily I don’t eat french fries much 😃.
That’s good! With more and more rivers and not rivers only, with not that bright future, this one seems to be safe. When it comes to fish especially salmon, let’s hope they solve this issue you pointed out soon.
Always learning something new from @adsactly community.
Well done @bigtom13!
Thanks for the kind words, I really appreciate them.
They grow some serious potatoes near this river, I'm telling you. I crossed the Snake twice on this trip and both times were right in the heart of potato country.
I don't know what the answer is for the salmon, I truly do not. I have a cousin that was the hydrologist for PG&E so I heard a lot about the dam caused mortality rates. It is significant, I can tell you that.
One last word. I love the Hells Canyon and have all my life. I think it would be a formidable piece of water if there were no dams.
Such a detailed description of both the river itself and the history. The pictures are absolutely gorgeous. I can imagine floating along that river pulling in lots of fish. I have always wanted to do some Salmon and Steelhead fishing. They sound like really fun fish to bring in. I must at some point find the time to explore the US a little more. There are so many treasures out there. Thanks for sharing.
My Dad and I were in my 12 foot boat on the Snake one day in December. It was a mixed rain and snow and cold enough to freeze the guides on our fishing rods. After a couple of hours he asked me " Are we Steelhead fishing or Duck Hunting? I can't remember." That was enough for that day :) I'm really glad I had a Honda outboard, cause it would have been a perfect day to have to row to shore and walk to my pickup :)
Hello friend @bigtom13, how are you feeling? I hope you are well.... first of all I would like to apologize for all this time in which I was a little away from steemit and @adsactly, actually I was very busy with my final thesis degree, for all that I apologize, but well.... I'm back, maybe in one of these days I'll go to your discord chat and talk a little bit...
From what I read in your post this river seems very interesting to me, in fact I didn't know it existed, there's one thing that strikes me as particularly interesting is that salmon runs are worth more than $50 million a year for Idaho, a landlocked state. However, you also mentioned that this is not its net value, since it is very difficult to calculate because many are caught, however you mentioned that the total value is 500 million dollars.
Another thing that caught my attention is that this river is a source of renewable energy, since 65% of the hydroelectric energy produced in the northeast comes from here, without a doubt this river must continue to be exploited (in the good sense) but knowing that all the resources of this world are finite, that is to say that they can be exhausted, so it must be a correct exploitation.
This river has a lot to give, however the amount of money it generates is large, but it is very good to get as much benefit, as the generation of hydroelectric power, in short... Greetings to you friend @bigtom13 and to all the community of writers of @adsactly, without further ado I say goodbye, I hope for your next contents, greetings from Venezuela!
Thank you for the very kind words.
It's an incredibly delicate situation. Both sides have valid points. The good news is that so far, both sides are talking about what they might be able to agree on.
Hello @adsactly Sir.. education history...In the education process, a person is encouraged to develop the full potential of the underlying qualities and is assisted in achieving the skills needed for establishment as a productive member of society. Learning in the general sense is to acquire knowledge or skills. In a broad sense, learning is the process of knowledge-learning process. But education is the continuous practice of developing full potential. The word 'Bangla' has come from the 'rule' of metal. Which means to rule or advise. On the other hand, the English word of education comes from the Latin word educareum or educatum. The meaning of which is to bring it out, to bring out the inner potential or to develop it. Socrates's "education is the delusion of truth and the development of truth." Aristotle states, "It is a good idea to have a healthy mind in a healthy body" In Rabindranath Tagore's words, "The education is so that not only does it serve the information but also makes our life consistent with the belief in the universe."..
At first glance, I thought that river is called snake due to many snakes in that river. But then, i am totally wrong, lol.
This is such a pretty place!

Beautiful nature 😀 really never heard of Snake river before...
It's quite a place. Glad I got to share a little of it with you.

In the not too distant future wars will be fought over water, rivers and dams.
Yes they will. There is a huge 'battle' of words shaping up in the desert Southwest over the Colorado River. I did not mention it, but proposals to run a canal from the Snake or Columbia to the desert are circulating again.
Excellent ... I recommend reading: https://steemit.com/education/@luisroalm/ensenar-matematica-desde-la-realidad-modelizacion-matematica
@adsactly how you able to get all the information , by the way very nice and interesting blog, i just have a question. whats ur profession buddy,
As it happens I am out on a road trip and have crossed 5 of the 6. Particularly on the Snake, I grew up in the region and am seriously familiar with it. I also do enough research to cover my words. It's not what I don't know that hurts me, it's what I know that's wrong :) I am fully retired. Was mostly a heavy equipment mechanic.
Building dams, industrial wastes and the like, all are hampering this beautiful river.
