Next time you're at Wally World add these items to your list.
Children's balloons, fishing line/string or twine & split shot lead sinkers. (Less than $5.00 total, and it will probably last you all season.)
Find a spot in the creek where you want setup equipment then go up stream a bit. (Anywhere from 50' to a 50 yards depending on the stream.) Take about 3ft. of twine string fishing line. Stay away fro ribbon, it floats. (Actually you want about 1 1/2' longer than the stream is deep. If the stream is 1' deep, make your line about 2 1/2'-3' long (Allow for tying to the balloon.)) Blow up the balloons and tie one end of the line to the them. Then attach to small split shot lead sinkers on other end. (No need to get crazy. 2-3 pieces is fine.) Do this to about 2-3 balloons. (You can always do more balloons and vary the weight of the sinkers. Add some more split shot, or take away one.) Go upstream and release them. Watch them go down the gut of the steam to see where the gold will settle (Lead being close to Gold in weight, will stop/get hung up, the same places gold will.)
Now dig, dredge, etc..........Don't forget to send me 10% for the tip!
Variation: (I have not tried this one.) Instead of fishing line and weights, take your snuffer bottle and pump some water into the balloons. (Vary the amount of water in each.) Blow the balloons up and tie the ends and let them go up-stream. The water in the balloons will find where the gold settles out.
