One of my projects made the front page of the Yakima newspaper. Since the paper tends to paywall these things in short order, I thought the blog would make a handy archive.

In the Yakima Valley, with its 500,000 irrigated acres and its network of leaking canals, irrigation induced seasonal wetlands are common. In the floodplain, upwelling hyporheic / phreatic river water can be masked by irrigation induced hydrology, but only while the canals are full, or recently so. During this January visit, long after irrigation diversions have ceased, there was no mistaking the dominant river-induced groundwater hydrology at the site.
