Had a .20 acre silted in pond with a great fish stock and expanded it to a 1 acre pond. It was so satisfying to open the dam to save the fish. Added a level of difficulty working in the sludge and 3 weeks after it's till not fully dried. The missing part is the near 2 hours of saving fish that tried to stay in the old section using the excavator bucket. Nearly lost my boots in the muck!
