Learned a thing or two. I knew the sandbars move often in Lake Michigan, but I didn't quite understand why.
I noticed that 3-4 days after a big summer storm, the water was often very still. If I can find pictures, I'll put them up.

Interesting. Lots more happening than
meets the eye.

This was taken 2 days after the worst storm of the summer, it took all the energy with it.  Chill stretch of weather = extended sand bar.  Here is an example of a "river of sand". I can usually float down the shore if the pool between bars is deep enough. I just look like a weenie   So I think it works different on the lakes compared to the ocean. We get big ice shelf that builds up thru the winter and that pushes a large section of sand bar up to the front, you can see how many rocks are there after the ice melts compared to the summer.  As spring arrives, the winter sand/rock bar starts to go back out.
I realize no one asked for this, but it made me think of the differences between the California beach they presented and the Lake Michigan beach I know.

Chad, this was really awesome! I like seeing the pictures and then having an understanding of what's happening because of your explanations! That second to last picture reminds of the "rivers" of rock out at Railroad Buttes here in SD. It's overwhelming at times the amount of rock when it's like that!

Wonderful photos to explain sand/rock movement in large bodies of water.
We used to visit relatives who lived near West End Beach in Chequamegon Bay, Washburn, WI.
There was sometimes tidal action, with the tide rising and lowering. This resulted in the water level encroaching the beach by up to 20' at times.
When the water receded, the sand beach was often covered in rocks/shells. Sometimes the next tidal activity would wash these back out into the lake.
Visitors would often pull their boats partially onto the beach and tie them to a tree or one of the mooring posts available. They would then have a picnic in the park and/or let children go in the playground. Some would walk to nearby stores to get supplies or browse. Many were surprised to find their boat was beached and the water level was way beyond their boat.
I remember people asking others to help them push their boat back in the water when this happened. Some of the boats were fairly large, say 16' or more, so this was not an easy task.
Water is very powerful.

Now, I've only lived near the beach for less than a year, so maybe I haven't overheard people talking about it. But I would wager we don't see much tidal action on the east side of the Lake Michigan.
Would be wild to see lol
Now I'm curious, thanks for sharing  |

Yes, it was kind of crazy how much the water level went up and down. It did not only happen during storms, but on other days and was somewhat unpredictable.

I'm learning between the Yellowstone river banks and places like that you guys are spoiled  |

Dang 'dule! That's the kind of environment that I imagine felt like being in a sandblaster! |

Didn't really know where to put this, if anyone has a better idea, please let me know
Just showing my walk to the lake shore and what the back dunes look like if anyone hasn't seen them before
Sorry for the shaky camera and heavy breathing lol

In Oregon due West of where we live, the Winter storms can move several feet of sand off the beaches which exposes large areas of gravel, making agate searches more fruitful. Sometimes this can be as much as of to 10-20 feet of sand. This doesn’t mean you can’t find agates in the summer, but not in the abundance you can when the sand is out. Then around April the sand begins to wash back in onto the beach and buries the gravel bars again.

Sand movement ?
Interesting computer simulation of sand bottom Lake Okeechobee being blown by the eye of 1928 hurricane from 1:50 to 3:20 of video.
Okeechobee is 20 to 25 miles across and averages 5 feet deep.
Red is highest water height(pinnacle lake depth was about 29 feet above mean water level)
Lavender/pink is lowest water height.(so the lake basically had no water in the upwind sides)
Arrows are constantly changing eye wind direction.
Numbers at arrows is wind speed in knots(1 knot = 1.15 x mph)
Graphs at base are lake cross section showing dynamic water depths as eye wind changes direction.
