Up here in NY, we are 4 inches over normal for the last two months. Last Thursday we has a 2.5 inch gully washer, which is fare rarer in NY than southern states. Everything was saturated before it rained, so it was all runoff! I was out rescuing our driveway in the downpour, and diverting chocolate cake batter from entering the pond. For the most part the effort paid off. The driveway only had minor damage, and the pond didn't get too muddy. Lots of other driveways had bad washouts, and a road washed out 2 miles from us.
If our pond was empty, it would have easily filled in this one event! Raging torrents of water going down the little creek that normally dries up in the summer.
