~~~STRANGE HAPPENING ON LAKE WASHINGTON~~~

How about the following:
Underwater seiching - Loch Ness and Lake Champlain
unmuseum.org

Both Loch Ness and Champlain also have a deep layer of cold water, called the hypolimnion, under a layer of warm water, called the epilimnion. Perhaps these characteristics, suggest supporters of the lake monster theory, are needed for the creature's survival.

The Seiche

The long, deep and layered nature of these two lakes also make them susceptible to another strange phenomenon. A wave called a seiche.

A seiche is a standing wave in an enclosed body of water, such as a lake. The term "standing wave" means that the wave goes back and forth between two fixed boundaries. You can observe a standing wave whenever you watch a guitar string being plucked. The wave goes back and forth from one fixed point on the guitar string to another.

In the case of Loch Ness and Champlain, the fixed points are the farthest ends of the lakes. The wave moves back and forth between them. To picture what is happening in the lakes, imagine what goes on when you sit at one end of a bathtub and suddenly get up. The water your body displaced at one end of the tub comes rushing in to fill the void. As the wave hits the end of the tub, it turns around and heads back to where it originated. This wave goes sloshing back and forth in the tub many times before it loses energy and levels out. By standing up, you have created a seiche in your tub.

The same kind of wave occurs in the lakes. In the case of Lake Champlain, the wave may be from 30 feet to 300 feet high! Why does nobody notice a wave that high in the lake? Because the wave doesn't happen on the surface, but underwater. This huge wave moves along the boundary between the warm water layer and the cold water layer.

Boundary Layer

The warm and cold layers of these lakes do not usually mix. The boundary is very much like the boundary between the surface of the lake and the air above it. In the same way the waves we usually see move along the water-air boundary, the giant seiche wave moves along the warm water-cold water boundary. A giant 300-foot wave might be roaring along underneath the water, while the surface is smooth and placid.

What starts these waves? Scientists think that prevailing winds running the length of the lake can cause a build-up of the epilimnion (warm water) at the end forcing the hypolimnion (cold water) to the opposite end. When the wind stops, the warm water on the surface starts flowing back to its regular position. This is very much like getting out of the bathtub in our example. The cold water layer then suddenly rushes back to the end the warm water vacated. This giant, powerful wave of water then bounces back and forth between the ends of the lake to make a seiche. It can take 4 days for the wave to go the entire 60-mile length of the main part of Lake Champlain.

From Wikipedia:
Lakes in seismically active areas, such as Lake Tahoe in California/Nevada, are significantly at risk from seiches. Geological evidence indicates that the shores of Lake Tahoe may have been hit by seiches and tsunamis as much as 10 m (33 feet) high in prehistoric times, and local researchers have called for the risk to be factored into emergency plans for the region.[9]

Earthquake-generated seiches can be observed thousands of miles away from the epicentre of a quake. Swimming pools are especially prone to seiches caused by earthquakes, as the ground tremors often match the resonant frequencies of small bodies of water. The 1994 Northridge earthquake in California caused swimming pools to overflow across southern California. The massive Good Friday Earthquake that hit Alaska in 1964 caused seiches in swimming pools as far away as Puerto Rico. The earthquake that hit Lisbon, Portugal in 1755 caused seiches 2,000 miles (3,000 km) away in Loch Lomond, Loch Long, Loch Katrine and Loch Ness in Scotland [1] and in canals in Sweden. The 2004 Indian Ocean earthquake caused seiches in standing water bodies in many Indian states as well as in Bangladesh, Nepal and northern Thailand.[10] Seiches were again observed in Uttar Pradesh, Tamil Nadu and West Bengal in India as well as in many locations in Bangladesh during the 2005 Kashmir earthquake.[11] The 1950 Chayu-Upper Assam earthquake is known to have generated seiches as far as Norway and southern England. Other earthquakes in the Indian sub-continent known to have generated seiches include the 1803 Kumaon-Barahat, 1819 Allah Bund, 1842 Central Bengal, 1905 Kangra, 1930 Dhubri, 1934 Nepal-Bihar, 2001 Bhuj, 2005 Nias, 2005 Teresa Island earthquakes. The February 27, 2010 Chile earthquake produced a seiche on Lake Pontchartrain, Louisiana with a height of around 0.5 feet. Seiches up to at least 1.8 m (6 feet) were observed in Sognefjorden, Norway during the 2011 Tōhoku earthquake.[12]

thanks for sharing an interesting observation. it is people like you who are concerned with earth changes by making others aware of how diverse and subtle these chsnges occur.

Oh no, not waves in a lake!!!! AAAHHHHH!!!! There are waves in the lake, we're all gonna die!!!!



unpin this crap.

earth farts...that's all it is...yeah...earth farts.

hahahaha

you stupid

It's called high tide and low tide, or it was due to the wake from a boat further away she couldn't see.

stupid

possibilities

seacraft, NOAA or the Navy (sand point naval base is there so is NOAA)
sinkhole
small fault under the lake at the north end

NOT likely a sturgeon as that was too much water displacement

fwiw, I lived 3 miles from there in the 80's for 6 years and those are the only explainations I can think of.

Bill Gates underground lake house is right down the pike. Invisible boat? Sub to scuttle the kids to school?

Stay out of the water.

The following was probably posted elsewhere but it might be the answer for the choppers, even though the search was further north:

the Pattern is unraveling. the Last Battle approaches.

HMMM, NO. aliens love the water? Not a reason.

let me tell u something about washington
it is very wooded and has many lakes in wooded areas that are not studied

i was a teen and me and my friends one nite were at our hangout in the wooded mountains
where there is a river
we were sitting on cars talking listening to music
when we saw something aways away glowing in the river coming upstream
we watched it and as it got closer all we could see was something moving very fast against the stream and glowing
we got scared the girls jumped on top of the cars screaming
the guys tried to find their guns but for some reason couldnt
the thing stopped all of a sudden right in the middle of the river in front of us
and started coming our direction fast and glowing
i was so scared
and all of a sudden when it got near the bank it vanished

i to this day remember that and have no idea what it could have been

the writer makes it very clear it was not the pattern of a wake from a boat.

Eerie! I think all of us had, at one time or another, an unexplained happening in our life

As I recall, there were some strong earthquakes in the Pacific Tuesday, May 10th. I think one occurred early, around 3am. Even with that distance, is it possible it could stir the lake water up?

these people have never seen this, in 30 years, so this statement does not jive.

ACTUALLY NOT DUMBASS

lets pin YOU instead in the behind. Obviously it was something abnormal to the people living there for so long. Abnormal enough to film it.

Do you have any idea how long this lake is? I do, I grew up in seattle and lived a couple of miles away from here the lake for 7 years.
The inlet theory does not hold. The ship canal is in the middle next to the evergreen point floating bridge and is controlled, ie: no real "flow" of any kind.
the ends of the lake are approximately 20 miles apart stretching from Renton at the south end to Lake Forest park at the north end.

that is freaky. im glad you videotaped it.
i wouldnt swim in that lake anymore if i were you.

i am speechless!!!

First, I'm not claiming to be any such expert on Sturgeon. With that said, I have seen my fair share of the fresh water marlin. I have never seen them cruising the surface in such a way to produce the wake shown in that video, in fact the only times I've ever seen them at the surface is when they are breaching the water (usually while trying to shake a hook). Sturgeon get big, real big, but not big enough to create the size of wake that we see.

Like I said, I'm not an expert by any means but IMHO, whatever created that anomoly was definitely not any species of fresh water fish native to the Pacific Northwest, 'specially a bottom feeding dinosaur.

(Pardon my spelling errors, only running on one cup of coffee)

I'm no expert, either, and I just showed my son the video for the first time and mentioned the fish theory, and we both agree that it was No Fish.....
