River is coming down, but I just looked and they only have one gate open. They will let Deep River get back down to normal and then open the gates to bring Jordan down. They can let Jordan down almost a foot a day, but will not do it until Deep River is down.
Here is a map I found online. My understanding is that the total acreage in the Jordan basin is twice the acreage of that in the Falls Lake basin, but I could not find the numbers. As you can see, Jordan has four fairly good-sized urban areas in the watershed, so lots of run-off from those urban areas along with a big rural area as well.
