Very well done in terms of content and your delivery, Dr Bradbury. This topic is so interesting to me. I earned a BS in finance but really wanted to go into oceanography. Unlike many places in the US and the world, we are spoiled by our greatest resource, the Great Lakes. However, having an ample supply of water is one thing, having an abundant supply of clean drinking water is another. How our water tables change and how long the deep aquifer tables cycle is fascinating. Did you say some up to 1,000 years? I grew up in the north suburbs of Chicago and we always had Lake Michigan water. We didn't need a water softener. I retired and moved to Twin Lakes, a few years ago. I have said to many of my friends that I took good drinking and bathing water for granted until I moved to Twin Lakes. This water is horrible, I go through about 50 gallons of Culligan bottled water/month and that is just for me to drink, make ice cubes, and cook with. I selected the 5-gallon Culligan water bottles from a spring in Nothern Wisconsin. (Not distilled or filtered) It tastes the best. You spoke about the deep wells that go down 2,200 feet. Is that water generally much cleaner than the shallow wells? Assuming the casing goes down to the deep source? One would think so. The twin lakes of Elizabeth and Marie are very clear and Lake Geneva is only 25 minutes to the west. I had heard many moons ago that Lake Geneva and Lake Zurich, Il were connected by the same deep aquifer. Is this true? How long the will these lakes remain clean, clear, and healthy to swim in? I have taken a ton of aerial photos and videos with my drones of LG and Twin lakes. I am seeing more and more algae through the ice and that is concerning. Both lakes this summer were flagged for certain periods because of the bad algae blooms. From what I have read, more and more very clean lakes in Wisconsin are suffering the same fate. How hard is it to legislate what the farmers can use in their fields? Is it a pipe dream to think that one day, farmers would not be able to use pesticides within a 10- 20 miles radius of lakes? When you look at the topography, both LG and Twin Lakes basically are sitting on big bowls. Thanks again for your wonderful, easy-to-understand, presentation.

I recognized your rocky thumbnail immediately❤

Good

they dont take care of this lake like they used to

Now that’s climate change.

The sound dropped out when you switched to the second speaker...?

As the graphic approaches modern times, Lake Michigan shrinks to half its current size, then the video ends. Hmm.

don't ever step in to one of these, because you might as well come out from the other side of the earth.. 🤣 ... jk! but such springs generally have little to no surface bed over those moving sand surface... you realise that when you put your hands or a long stick in them.

Best project and easy 👍👍, thankyou for this👍👍🙏

Thank you for your work. I have a better understanding of what happens to precipitation as it passes through the bedrock and finds its way out as seeps and springs. Looking forward to seeing the year 2 of 2 work on Lafayette, CO.

I’m from Michigan and I always find it fascinating my home used to be covered in snow ⛄️ ❤

Thank you for putting these proposals online. They are insightful!

Thanks for putting these here for everyone. They help my understand of how these studies are performed and priotizied.

I like the trilobite

One thing we need to do is move water from the ocean back inland to places we need it and if we can do that while generating clean energy we have a chance to mitigate climate change and still have a prosperous future. It is really, really hard but it is not impossible. The biggest idea I am trying to express is tunneling aqueducts from the coast, in this case the west coast of the USA inland to feed combination geothermal power and sea water desalination plants. The idea seems to be so big that no one has considered it possible but I believe it is not only possible but it is necessary. For over a century the fossil water contained in aquifers has been pumped out to feed agriculture, industry and municipal water needs. The natural water cycle cant refill fossil water deposits that were filled 10,000 years ago when the glaciers melted after the last ice age. Without refilling these aquifers there is not much of a future for the region of the United states. As a result ground levels in some areas of the San Joaquin Valley have subsided by more than 30 feet. Similar fossil water depletion is happening in other regions all around the world. TBM and tunneling technology has matured and further developments in the industry are poised to speed up the tunneling process and it's these tunnels that are the only way to move large volumes of water from the ocean inland. The water is moved inland to areas where it can be desalinated in geothermal plants producing clean water and power. In many cases the water will recharge surface reservoirs where it will be used first to make more hydro power before being released into rivers and canal systems. It's very important however to not stop tunneling at these first stops but to continue several legs until the water has traveled from the ocean under mountain ranges to interior states. Along the way water will flow down grade through tunnels and rise in geothermal loops to fill mountain top pumped hydro batteries several times before eventually recharging several major aquifers. What I am proposing is essentially reversing the flow of the Colorado River Compact. Bringing water from the coast of California first to mountaintop reservoirs then to the deserts of Nevada and Arizona and on to Utah, New Mexico, Colorado and Wyoming. This big idea looks past any individual city or states problems and looks at the whole and by using first principles identifies the actual problem and only solution. Thank you for your time, I would like the opportunity to explain in further detail and answer any questions.

Thanks!!!

I just finished watching your WNitL talk on WPT! I'm going to watch the whole video!! And keeping my eyes out for those ripples!

love to see this video....hope one day I can go and visit this repository...

We did this today and it worked really well. Thank you!

NICE BRO NICE BRO

lullu ok

Good job

Best

remember its plus or minus a couple weeks on these dates...ha

I am making a mini-documentary on the Ice Age Trail in WI for one of my graduate classes. How could I receive permission to use a part of this video in my documentary? Thanks!

Great one thanx

What year is this from?

Classic!
