Using Mr. Pid's useful "Things that work" format - thank you, Sir:
We used the Katadyn Base Camp filter last week to filter plenty of water from the silty Tanana River.
To reduce silt, we used a settling pond first, then let the water drip through a nylon sack to reduce filter clogging - until finding a tannin-stained creek later with less silt. The rest was set it and forget it; fill and drip 5 to 8 gallons was effortless during our 8-days out. Worked flawlessly for us.
