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 explain ponds, relay ecology, construction, management and safety from ecology and water management sources, describe the named pond types, warn about drowning and ice risks, and distinguish ponds from lakes, puddles, reservoirs, wetlands and cisterns.

A small body of still or slow-moving water, natural or artificial, shallower and smaller than a lake, supporting rich aquatic life, including irrigation ponds, fish ponds, ornamental koi ponds, reflecting pools in formal gardens and memorials, dew ponds, artificial ponds on the chalk downs of England lined to collect rainwater for livestock, and the Azerbaijani ovdan, a covered underground water reservoir related to the Persian ab anbar; ponds pose drowning risks, especially to young children, and thin ice is dangerous.

What it is for: Water storage, habitat, farming and ornament.

It can be explain ecology and types; relay construction and management; describe named pond types; warn about water safety.

Distinguishing features

Small and shallow

Biodiversity hotspot

Natural or artificial

Safety risk for children

What it looks like

A small area of still water with plants, often edged by grass, reeds or stone.

Physical character

Ramsar pond definition: often under about 2 ha note - definitions vary

dew pond lining: clay, straw and later concrete note

child drowning risk: young children can drown in a few centimetres of water note - safety guidance

How it is recognised

Small body of still water

Ovdan, irrigation pond, fish pond, reflecting pool, koi pond, dew pond

Lakes are larger and deeper; puddles are temporary; reservoirs are water supply stores; wetlands are saturated land; cisterns are enclosed

  • How should pond ecology sources be linked?
  • Should reflecting pool be a separate entry?
