The Colorado River enters the courts (opens the original)
Read excerpt
First I wanted to plug this masterful new piece on the Rio Grande from Jack Herrera in the Texas Monthly. It’s richly reported and an urgent call about the crisis unfolding through the flows of a river, within a system, and across many boundaries. It’s long but I learned so much from reading this piece and recommend it. My main writing and research experience has been in the Colorado River Basin, but I’ve grown increasingly interested in how the two watersheds connect with each other geopolitica
Losing storage above and below ground (opens the original)
Read excerpt
Last week, researchers published evidence that intensive groundwater pumping in California during the 2020-22 drought led to permanent and irreversible damage in parts of the Sacramento Valley.1 This damage took the form of sinking land, one of the many undesirable costs of excessive groundwater use. Land subsidence occurs when large amounts of water are withdrawn from an aquifer, leading to the compaction of soils. Over time, subsidence can reve

More rights than water: a groundwater-surface water connection case (opens the original)
Read excerpt
Good morning, and back today with a new edition of Invisible Waters. I wanted to first start by sharing a couple of thoughts on a lawsuit in Nevada that centers around the Muddy River, and reflects some of the challenges in recognizing physical connections between groundwater and surface water within a legal structure that historically ignored them. Back as a reporter in 2019, learning more about the hydrology of this area of Nevada was a big part of what got me interested in groundwater-surface
A tributary approach to learning the Colorado River (opens the original)

Hello, and welcome back to Invisible Waters! Popping up from a few deadlines at the end of the month to do a quick dispatch (more to come soon). Mostly I wanted to share a cross-post with the California Water Blog at UC Davis’ Center for Watershed Sciences. Starting in January this year, I helped facilitate a graduate hydrology seminar at UC Davis on the Colorado River with two incredible collaborators, Kira Waldman and Lindsay Murdoch. Each week, we invited a speaker from the watershed to offer
