### water:

Shoal
* are also important to trout during late spring and early summer for similar reasons
  - bodies of water
  - more vulnerable to predator attack
* is water
+ Shoaling and schooling, Schooling: Fish :: Ecology
  * When schooling fish stop to feed, they break ranks and become shoals. Shoals are more vulnerable to predator attack. The shape a shoal or school takes depends on the type of fish and what the fish are doing. Schools that are travelling can form long thin lines, or squares or ovals or amoeboid shapes. Fast moving schools usually form a wedge shape, while shoals that are feeding tend to become circular.

### water:

Soft water
* can cause corrosion in pipes.
* dissolves appreciable amounts of lead, which is poisonous.
* flows from deep in the earth and contains sodium.
* has fewer minerals than hard water
  - less insoluble ions than does hard water
* increases the saline content.
* is best for diluting to the proper strength
  - easy to make lather with soap
  - essentially free of dissolved calcium or magnesium
* requires less soap or detergent than hard water.
* wears away hard rock, if it persists.
* weekens the gluten during mixing and fermentation.
+ Psoriasis: Dermatology
  * Dry arid climates seem to aggravate the condition. Washing your hands has a drying affect, which triggers the condition. When washing, water removes oils from our body, and has a drying effect on our hands. Washing with Psoriasis removes the dry skin, but then the skin underneath is raw. Hard water appears to worsen the condition in dry climates, but not as much in humid areas. Soft water appears better.

Softened water
* can cause the anode to wear out more quickly.
* carry sodium salts.

Soil water
* Most soil water holds capacity.
* Some soil water travels down to the water table and becomes ground water.
* can freeze and lift plants out of the ground.
* is available for plants to extract and use
  - drier through the winter and stayed wetter through the summer
* is the amount of water available to a crop from the soil
  - water held in pore spaces between soil particles

Spring water
* comes from a natural spring in the ground
  - spring, such as an artesian well
  - with or without fizz
* is magnetized
  - used for both domestic and irrigation purposes
* possible source for livestock at certain locations.
* rises naturally to the surface from underground.
* source of surface water and surface water is protected by Wisconsin law.

### water:

Stagnant water
* can become a breeding ground for insects and harmful bacteria
  - create more problems than it solves
* created by Eurasian watermilfoil mats provides good breeding grounds for mosquitoes
  - hydrilla mats provides good breeding grounds for mosquitoes
* is an ideal source of infection
  - found in parts of it, and in others the carcasses of animals
  - often a breeding ground for mosquitoes
  - the favorite breeding ground of mosquitoes
  - usually more damaging than flowing water
  - where the infecting mosquito aedes aegypti breeds
* kills plants quickly.
* left from monsoon rains can increase mosquito activity.
* produces the worst emissions because the decaying vegetation generates methane.
* sitting in the reservoir during the off season can be a breeding ground for bacteria.

Stored water
* can contribute to mold and bacterial growth.
* is released to generate electricity.
