They can be as long as you like. In the old days, they were hundreds of feet long. Your sluice size is determined by your needs. Are you back packing it? Do you have a base camp to go big? How willyou handle the run off. Thats what determines your sluice needs.
No problem in most places exceptions in some parks that only alow 6 inch trowels and pans California is still gold country as long as You don't run a dredge (a soon to change law we all hope)

So, I gather that the length ain't a concern, legally?
As long as you have enough water flow to run the sluice I don't think size is an issue. The question is how portable do you want it, and what are you going to use as a water source? if it's just going to be a stream sluice I would stick with a 3 to 4 foot sluice this gives you a good cross between portability and productivity with the ability to use only the stream current to run it of course the 8 footer setup right could perhaps recover the finer gold better but may need a swifter flow of water maybe even a water pump although if you're just using it in a stream this may not always be available year round. many factors play in the size and shape of a sluice the 4' sluice just seems to be a happy medium.

Well, like ya mentioned, I'd like to go after the fine/flour gold too. That's why I'm thinkin' about a longer box. Got plenty of water flow on the Calif. claim, so that ain't no problem. Got a little claim in Calif. and another in Nev. Just 20 acres each, but I'll never have the time to work every inch. Jus' me an' ol' Danny, my dog. He ain't much help.
