Can't fish in pond

OK, I was having this issue and wasted so much time trying to mess with the topography of the pond and that ultimately had nothing to do with it. So in case others are still having this problem, this is what worked for me. (I'm playing in a house that I downloaded from the gallery and there is a pond on the lot.) In order for me to fish in that pond, first the fishing sign had to be IN the water, not out on the shore. Second, your Sim has to first go fishing somewhere else and get at least one fish. Once your sim has gotten one or more kinds of fish from one of the pre-made fishing holes in the game, then those are the fish that it will show that you can stock your pond with. Select the kinds of fish you want to stock in your pond. But then instead of clicking on the sign to start fishing, you have to click on the WATER of the pond. That is when I finally got the option to actually start fishing. I hope this helps some other folks. This was driving me nuts.
