Water Quality of Community Ponds
The Environmental Services staff monitors 23 of the 40 plus ponds throughout Broomfield. These ponds are easily accessible (e.g., The Trails Pond), used for
Field observations and measurements
When Broomfield staff visit a community pond, observations are made of wildlife, waterfowl, trash, natural debris, algal blooms, and anything else that may affect the water or aesthetic quality of the pond. Based on these observations, other departments in Broomfield may be asked to help resolve issues such as trash, a broken aerator, or a harmful algal bloom.
In addition to observations, the following field measurements are recorded:
|Secchi disk depth||The
This depth measurement is used to estimate the depth of light penetration through the water.
|Temperature||Cold water holds more dissolved oxygen.|
|Dissolved oxygen||Necessary for survival by fish and
|Conductivity||Helps to identify
Typical tests performed on pond samples are:
These results provide a valuable tool to evaluate changes in water quality over several years. Changes could be due to illegal dumping of pollutants, overuse of fertilizers, sediment buildup in inlets or the pond, or severe weather events.
