What I think could help would be to research the "bog" plants. I think planting these in the area would help soak up the water and would also look nice. I have an area I am looking to do some planting in. It is a low area where water feeds into my pond and it seems to stay wet a lot. I would like to help dry this area out and make it look nicer. This planting would also help your frogs come back.

Thanks
