Cleaning a Muddy Pond

How can I properly remove thick, swampy mud from the bottom of my garden pond?
All the water from my garden pond has gone, it is now quarter-full with a green-black, thick mud. What is the best way to get rid of this, so i can either remove my pond, or refill it with water?
Thanks.

Answer:
If you don't want your pond anymore, just fill it up with sand and soil. If you do want to keep your pond, you can shovel it out. You can also try this which may work. Fill the pond up with water, then using a utility pump, start pumping. Keep filling it with water as the pump keeps working. You can probably get much of the muddy water out. Then use a wet vacuum to get the rest.
