I've seen this as well in my pond. My overflow which is basically a trench I dug out around the one edge of my dam was rushing harder this year then I ever seen it. My pond rose a foot easy and my fish were off feed for a while.... another factor could also be a lot of your BG could be on beds my feeding goes down a lot at this time as well.

I'd say give it 2 weeks and see how things are going....

The only difference between a rut and a Grave is the depth. So get up get out of that rut and get moving!! Time to work!!
