Can I use water from a retention pond to water my vegetable garden?

It’s actually a lake, but is now used as a retention pond. I’ve been watering my plants from the past few months with it and they seem to be thriving. I have tomatoes, cucumbers, peppers, squash, peas and eggplant. Is there any reason why this is a bad idea?
