Area to target?

[mallard]

Hey, I went out on the pond for the first time this year.

Air: 60
Water: probably mid-upper 40's
Clarity: Stained, not too clear

We've had a lot of rain lately, so water is still flowing in from springs, that is very cold, and also the water level is very high.

I was wondering where in the water the fish are. In the shallows, where they usually are in the summer, there is very little cover, and it is also very cold (from the rain.)

What are some good techniques for fishing over deeper water when you have no idea what the terrain is like down there? I tried letting a spinnerbait and a spoon sink down and go near the bottom and bounce off of it, but was really just running them blindly.

The ducks and geese have been in the shallows a lot lately though, and this usually means there is food. The only food I saw was flies, and a lot of them. Mostly black flies (if anyone has any ideas on repelling them, don't be shy.)

So according to the ducks and flies, I should fish shallow, according to the water conditions, deeper, and according to me, maybe invest in some scuba diving gear? ??? ;D
