Salmon Ladder

I was in my friend’s room the other day and their drawers reminded me of a salmon ladder. Salmon ladders enable anadromous swimming fish to be able to swim past a damn to continue their migration and eventual spawning.

Chain dam fish passageway project

I went biking several weeks ago, and while on my trip, I came across the enormous structure. The structure spans the entirety of the river, and was a quite impressive piece of engineering. I could hear the rushing water from far away, and I had noticed that down just a bit from where the water flows over the edge of the structure, there were several trees submerged. In days prior, there had been heavy rainfall, so I was curious as to if some of the forcefulness of the water moving maybe was due to a higher volume being present as a result of the rainfall drainage. The structure is, as the sign suggests, a fish passageway (that is, the little compartment on the side that does not drop over the edge), though I am not sure as to how effective it is, given that other forms of fish passage projects don’t have a particularly successful track record.

Worlds Shortest River

Everyone has heard of the worlds longest river, the Nile, measuring a staggering 4,132 miles. However, I doubt most have heard of the worlds shortest river, at only 201 feet long. Named Roe River, it flows from its headwaters in Giant Springs, Montana, before merging almost immediately with the Missouri River. If we were to place a typical American river barge at the beginning of the river, it would only have to travel 6 feet before entering the Missouri.

Hiking with rivers

On our hike at the Delaware Water Gap, I noticed a stream flowing down the landscape. It had been fairly wet in days prior, so there was a lot of water built up in the area. Though a small body, the water moved and acted with the full force of a river as it cascaded down. In some spots, it even separated, braided and rejoined, becoming an actual miniature river.

Venice Flooding

This is an image of the massive flood that has been taking place in Venice, Italy in the past couple of weeks. Just like Jacob and Henry’s Story Map about the rising water level of the Hudson River, Venice is in danger of rising water levels. This flood is that the highest the water has been in Venice in over 50 years. This flood is a wake-up call for Venice saying that there is not much more time before climate change and rising water levels completely submerge the city underwater.

Cellular Rivers

In biology, we were looking at different cells and the different structures. This is an image of epithelium tissue, and as can be seen, the gaps and spaces in between the different cells form irregular, random, and free flowing cavities. It’s fascinating because the image itself looks like a river that runs through mountains or fjords, flowing into a harbour-like structure, then emptying out into the ocean. It’s interesting to see some of the same geometric patterns appear both in both the macroscopic and microscopic worlds.

Sitting Water

I noticed water still sitting in the grate several days after it had rained. This reminded me of Becca and Michael’s presentation and how water would be trapped by the levees on either side of the river after a flood. It just found it interesting how the grate replicated this behavior.
