Its hard to believe that anyone would still be considering dams being any kind of good idea in 2021.
Fisheries problems, maintenance forever, dredging, unhealthy riparian areas, lack of point/bar development, cottonwood galleries down the drain, sediment loading, etc.
Here's a novel idea for those wanting subsidized water, how about we subsidize farmers where it rains to give you some hay? I've always wondered how much sense it makes to subsidize people living in a desert to grow crops there? For that matter, why not raise cattle where you don't need 20-50-100 acres per cow and you know, actually rains enough to grow grass?
We pay landowners to pump precious ground water, build dams, divert water all over hell and gone, to grow hay/alfalfa, etc. crops in places they weren't meant to grow. Then every deer, elk, and pronghorn for 100 miles come to the green fields, necessitating damage hunts, GF agencies paying game damage claims, fencing, etc. etc. etc.
Why not subsidize the farmers in places like Illinois that can grow 3-4 crops of alfalfa where we don't need to dam streams, pump groundwater, etc. Give the ranchers out West the hay for a subsidized rate?
Either way, we're going to pay a subsidy, I say do it in a way that disturbs natural systems the least.
