Lake Ventrul

Lake Ventrul was named in honor of Consul Ventrul who oversaw the construction of San Mortino, which was built along the banks. Its surface is just over eight square kilometers (2,000 acres) stretch from the north to the southwest, with a small lobe on the northern half trending southeast. The lake is approximately twenty meters deep (65 feet).

The people of San Mortino fish the lake as well as collect the silt that flows along. The pottery craftsmen prize the silt for its sturdiness and rich red-brown color.

There are no inflows except from an underground aquifer. The water is pushed up into the the lake through fissures in the soft red clay. It is believed the source of the silt is the aquifer itself as the lake is not significantly eroding its shoreline.

The only outflow of the lake is through the Big Mud River and evaporation.

The shallow parts of the lake spread out nearly 300 meters from the north-northwestern shore. After those shallows the lake drops suddenly to nearly its full depth.

The excessive sediment in the lake kills off most algae and plants, leaving small fish with little to eat. Instead this lake attracts a large number of reptiles and amphibians. These animals can eat the plants that grow along the shore. Cattails, ferns, and lily pads grow along the banks or in the shallows near the shore.
