Capabilities and Uses of Lakes
This is a question regarding a key feature in a world I am building, but not a help request or issue, just a curiosity.
A world I am working on is based around a rather large lake. This lake is built using almost 20 water planes (I am quite proud of it, as it is the first time I have ever made such a lake), meaning is not normal sea-level ("ocean") water. I am wondering if anyone has tested or otherwise knows the capabilities and uses of these lakes. Normal oceans allow for fishing, swimming (with Seasons), boating, and houseboat ports (with Island Paradise). I was playing a custom world which had a similar (though much smaller) lake. When I attempted to add a new lot (via Edit Town) on the shore of this lake, I got the message "lots can not be placed on lakes" while I was able to place the lot partially or entirely on normal sea-level water. This lake did, however, have a small dock house lot on it. This tells me that lots are perfectly fine being placed on lakes in CAW, but that lakes are more restricting than normal water.
My questions here are:
Can I build houseboats on a lake?
Can Sims travel across a lake on a boat?
Can Sims swim in lakes?
Do lakes provide for fishing?
