# Add River To shape the bottom of our valley we will now create a [River Layer](/reference/terrain/shape-layers/rivers.md). When you first add it to your terrain World Creator will automatically generate a river network based on your terrain. As we don't need that simply press **Clear Rivers** on the left side while in **Edit** mode. After that we use **Shift + LMB** to place a new spring and then **Ctrl + Shift + LMB + Drag** to drag out the rest of our river stream from that spring.
