Ed and Leah propose to send this letter to WSSC about the Jan 2006 WSSC discharge into Sligo Creek |
Help monitor Sligo Creek from Kathleen Michels |
As you may be aware all of our streams- including our own Sligo Creek- are
suffering from lesser or greater degrees of pollution and degradation due to
human activities.
One way of keeping tabs is monitoring of what insect larvae (macroinvertebrates) live in streams over time. Some (such as mosquito larvae) can withstand high levels of pollution that kill off everything that eats them (frogs, fish, other insects such as dragonflies); others such as Mayflies (well known to trout fisherman) are very sensitve to pollution and can only exist in clean streams. So the biological health of a stream can be assessed by careful monitoring of insect larvae over time. Some are beautiful. Some rather ugly but all are interesting. If you like the outdoors, have a little time, and are interested in exploring another dimension of the world around you - consider getting trained and spending a occasional hour walking in the stream. A GREAT activity for kids as well.
