Coastal water works great. Once through cooling from Diablo only kills 800 lbs of adult fish per year. Yes it sucks in fish eggs but the way the anti-nuclear industry phrases it is "it kills 1.5 billion fish in early stages of life" lol. A single tuna fish can make 5 million eggs per year. Away from the coast you can do dry cooling with almost no water, going straight to air. It's just more expensive so it's not done often.
