This was the scene at about 1pm this afternoon where the Arroyo Seco joins the LA River.
...a movie I took panning down the Arroyo Seco (note: it's San Fernando Road, not Avenue 26, as I say in movie):
... a still view from under the Avenue 19 bridge, looking out onto actual whitecaps on the LA River.
... and looking down the final yards of the Arroyo toward the river.
