A quick calculation would reveal that Zhuwei Lake isn't that big and covers about ten thousand acres of area. Dredging to an average depth of one meter would yield six or seven million cubic meters of sediment.
Wang Shouzhe had seen dredging boats in this world.
They operated manually, using dredging forks to scrape sediment onto the boat. Each boat can only hold about ten cubic meters of this muck.
Ordinary cleaned sediment is inherently rich in organic matter and makes excellent farmland fertilizer, replenishing soil fertility, once composted and mixed with other substances.
After all, in this era, the silt at the bottom of rivers and lakes doesn't contain any heavy metal accumulation.
