Weir

Weirs are artificial obstructions in rivers, lakes and shores that trap fish to make them easier to catch. Medieval Europeans used weirs extensively. Many were destroyed to ease navigation but some are still in existence, especially near canal networks.

This mod adds two types of weirs, a round fish-trap type and a linear type. The round weir works by luring fish into the cage which they then have difficulty escaping. The linear weir directs fish toward the fisher. The linear one can be placed on either bank but the dock should be on the "upriver" side (whichever you consider upriver).

Place the weir so that the two poles holding the dock up are roughly at water's edge. Depending on the steepness of the bank, there may not be enough dock space for a fisher to stand. Or, you may find that a builder never comes because they cannot get to the dock. In either case, delete the weir and try re-placing it.

You can add decorative extensions to your weir but don't block the entire channel if you also have fishing boats that need to get by.
