  - work quite well as irrigation sources
* are a great way to study ecosystems and all types of life forms
  - abundant in morainal areas
  - also an effective way to manage stormwater due to their large holding capacity
* are an important but threatened habitat
  - interesting aquatic ecosystem with numerous forms of life to study
  - as unique as snowflakes
  - better for watering than flowing streams, but they can become contaminated with heavy use
  - bodies of water
  - circular recharge or discharge areas
  - concrete with liners also which won t leak water into earth
  - frequently human-constructed
  - generally small, shallow lakes that have a more uniform temperature
  - home to a huge variety of microbes that represent nearly all kingdoms of life
  - ideal places for fish to live
* are located in countrysides
  - forests
  - ground
  - parks
  - rural areas
  - open to the atmosphere
  - relatively short-lived ecosystems

  - for swimmers, especially children
  - permanent, semi-permanent, or seasonal
  - go in sun or in shade
  - result from a wide range of natural processes
* change every couple months.
  - suitable substrate
* containing infective feces are important sources of infection for susceptible birds.
* created by beavers often serve as fish habitat.
* encourage slow percolation of storm water, recharging the local water table and streambeds.
* have components
  - cypress trees growing in or around a depression
  - existence
  - variation
* help animals live, ponds help plants grow, and they keep amphibians moist
  - provide water for many kinds of wildlife
* hold giant lilies and lotus flowers
* includes gaps.
* liners Pond liners keep water from seeping into the soil.
* lose depth
  - water through evaporation and seepage
* naturally degrade many of the waste products that cause problems in intensive systems.
* often support a large variety of animal and plant life.
* play an important role in the functioning of many modern facilities.
* provide an aquatic habitat for dragonflies, fish, newts, frogs and other aquatic life
  - great places
  - homes
  - water for livestock, and locally they are used for recreation
* raised fish have much more color than tank raised fish due to the sunlight.
* serve as watering sites for a variety of wildlife species.
* sometimes dry up during hot, dry summer weather
  - flood their banks during spring melts and heavy rains
* tend to go dry if they have an inadequate drainage area or because they leak.
* usually have muddy or silty bottoms
  - regulate the same water temperature ranging from the water's surface to the bottom
* vary in size from a few to many acres.
