New Mexico’s Dry Middle Rio Grande: More Data Visualizations

Alert Inkstain reader Rolf asked in the comments of last weekend’s post for a version of the above graph – number of days of low flow at the Central Avenue Bridge – with a threshold above zero. I usually set the threshold at 25, because our experience in the last two drying episodes – 2022 …
