Aaron: I know some potential applicators that you could contact, but none are less than 2-3 hours from your area. If you're planning to rehab the pond's fish population, this drought certainly offers the perfect opportunity - possibly without rotenone.
What size is your pond (surface-area x avg depth)?
Are you in any position to secure a private pesticide applicators license? ODA Pesticide Applicator Licensing Requirements
Rotenone treatments aren't overly difficult, providing that you know the proper procedures and have some basic equipment (a 12v sprayer works fine).
