Last winter, Robischon Gallery presented a suite of environmental shows that zeroed in on the topic of water, an urgent subject in the West. A standout among these strong exhibits was Stephen Batura: Floodplain, and although the entire show had fewer than a half-dozen paintings, the experience was just this side of transcendental. That's because the exhibit was anchored by a single spectacular work: the title piece, "Floodplain." Measuring forty feet across and rising twelve feet high, it was a highly expressive but nonetheless convincing rendition of rapidly flowing water. The casein-on-board painting relates to the many that Batura has done over the years on the subject of the South Platte River, including those times when it has flooded. In terms of size and charisma, "Floodplain" demands to have a big wall to hang it on. And it deserves to: It should be on permanent display in a local open-to-the-public lobby, or even a museum.
