If you are doing the work yourself then you will have to rent a trash pump and hoses. A 3" pump is probably the best option for your smaller pond. Once you get it pumped down you will then get a good idea of how fast it refills from the spring activity. You may have to pump it out several times to stay ahead of the inflow. A small tractor may have difficulty adequately removing sloppy muck if it doesn't have time to first dry out. Try to scrape and scoop out slop until the bucket scrapes firm bottom. IF the water won't stay down or low you may have to hire a contractor to do the job quickly and efficiently to stay ahead of rising water level.
