Ditch to the east has an overflow into Willow Creek, but most the flow (it is nearly stagnant and a meter higher than the creek) appears to cross under willow creek and comes out immediately on the other side. Water volume is about equal for both, but the east-west ditch seems to slow much slower than willow creek. Ditch is used for local irrigation. Willow Creek appears to be for draining to the river only.
