I need help with a drainage problem

I purchased a home and the pool area was extended. When it was built it was slanted away from the home and small holes were drilled in the base of the wall for drainage. When it rains I get a huge lake of algae and frogs and mess. I need to know how to correct this problem. The ground on the other side of the wall is even with the top of the wall. I was told to put in a French drain but would have to dig down 3 ft and run the line approx. 100 ft to lower ground to drain. Anyone have a better solution??
