body of water
Let an agent handle bodies of water by type, extent, status, use, protection and safety, as the parent of lakes, rivers and seas.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent handle bodies of water by type, extent, status, use, protection and safety, as the parent of lakes, rivers and seas.
Any significant accumulation of water on the Earth surface, such as oceans, seas, lakes, rivers, reservoirs, ponds and coastal waters, natural or artificial.
What it is for: Water bodies provide water, habitats, transport, food and recreation.
It can be map and monitor it; use it for water supply, transport, recreation; protect its quality and habitats; assess water safety.
