Ditch witch or skidloader around here costs around $50/day to rent. Even if it's a crude berm or ditch, it still would go a long ways to helping reduce your nutrient loads, and algae blooms, etc. Worth considering...I rented a skidloader for a week and moved 80T of limestone, built four berms, and almost killed myself three times while learning how to operate the thing on the job.
