Hey, that's a really good question! While I've written quite a bit about the potential for water-saving solar project on farmland (see my latest here: https://www.latimes.com/environment/story/2023-01-17/want-to-solve-climate-change-this-california-farm-kingdom-holds-the-key), I haven't heard much about solar on golf courses. To the extent I've heard anything about golf course closures in the Palm Springs region in the California desert (a very Colorado River-dependent, water-stressed place), the conversation has focused on adding housing or preserving walkable open space, basically a public park.

Those things definitely use a lot of water. See this recent piece by my colleague Ian James: https://www.latimes.com/environment/story/2023-01-29/colorado-river-in-crisis-desert-lakes-and-golf-courses
