Got called out for my sluice box setup on the Klamath River job.

My foreman, Dave, said my riffle spacing was way too tight for the fine gold we were hitting. He showed me his setup with 2.5 inch gaps instead of my 1.5 inches. I switched it over and our recovery rate jumped noticeably by the next afternoon. Anyone else run into issues with standard spacing on different sediment types?

That's a solid lesson on how the river itself can change the rules. The Klamath's sediment load shifts so much between spring runoff and late summer. A setup that catches flour gold in August might just pack solid with black sand during high water. Seen guys run the same box all season and wonder where their gold went.

I saw a guy on the Salmon last year running the same sluice angle from June to September. By fall, he was basically mining black sand. Stella_ross14 is right, you have to adjust for the river's mood. That box was so packed it looked like a magnet experiment. He'd clean it out and just stare at that dark, glittery mess with maybe three specks of gold. Some folks treat their gear like furniture you never move.
