Stakes!
HAMMER IN ALL STAKES---GOOD! By this I mean, the water in the creek moved my stakes around. My stakes were labeling my measuring places for water level.
My research has shown that the water level in the creek has gone down drastically since 12/12/06.
Station one had a depth of 27cm on 12/12/06. Then on 1/31/07, the depth was 5.5cm.
