São Paulo "...grew over dozens of waterways that, with the rampant urbanization of the 20th century, were channeled and hidden. It is estimated that More than 300 km of waterways are buried.... famous rivers... now flow invisibly beneath busy avenues."

Beneath the asphalt of São Paulo lies a giant hidden city, with buried rivers, secret tunnels, historical crypts, an underground subway system, and subterranean spaces that reveal an invisible and surprising metropolis.
São Paulo is known worldwide as the economic heart of Brazil, home to over 12 million inhabitants and boasting imposing skyscrapers that dominate the landscape. However, by diving a few meters below the concrete, we discover that the metropolis holds a giant hidden city, full of extraordinary secrets and forgotten corridors. What we see on the surface is only part of the story; beneath it, there is a complex universe that ensures the functioning of the capital and preserves centuries-old memories.

Been researching tons of historical images (maps, photos and illustrations) of Seattle for the book project... (More to come on that). There are such great stories, and images really punch up the narrative. I thought it'd be fun to post some #hiddenhydrology related ones here.

This summer, American Rivers began a multi-year effort with @yubariverpeople.bsky.social and the U.S. Forest Service to find out how many "lost meadows" there really are in California's North Yuba watershed. The results are surprising!

Rediscovering the Lost Meadows of California's Sierra Nevada
Mountain meadows make up a small percentage of the land area in the Sierra Nevada, but not as small a percentage as once thought. This is exciting news as they have an outsized impact, often functioni...

Here's a new edition of the Lost Streams of Washington, DC map. I've added more stream names, historic springs, and the pipes that carry runoff today.

Since 1905, 85% of the Detroit's historic streams and waterways have been buried for urban development, leading to long-term ramifications for Detroit’s most vulnerable residents. www.bridgedetroit.com/detroits-gho... Ghost streams, hidden hydrology + historic redlining contribute to flooding today.
