Female RES need a nesting area set-up. They lay eggs upon reaching maturity (5-7 years old and 6-7.5 inches long) whether or not they are fertilized by a male. If a separate nesting area isn't easily within reach, they may lay their eggs in the water. This isn't natural for them, and could cause the female to try and retain her eggs. If the eggs are retained in her body, they could rupture leading to very serious healthy complications to the female. Even if she has laid some in the water, she may still retain some, so setting up a nesting area for her as soon as possible is extremely important.
Here is a link that will help explain how the nesting area should be:
Nesting Area
I would remove the eggs from the water and dispose of them, and get a nesting area set up for her as soon as possible. RES can be very picky about their nesting sites, so read the link above carefully. Good luck!
