Sluice box: what is with all the water

sluice box
I was working on a small cutterhead dredge on the Caronie River in Venezuela in 2003. This dredge was very successful. You can see the lower pulp density and the enormous amount of water going through the sluice box.

When we did a cleanup, it amazed me to see the amount of fine gold that was captured. I spent the usual time worrying what we lost but the front of the box was very good with the recovery of fine Gold and even an occasional Diamond.
