You can have family FUN and help protect streams.

One activity we think is pretty special is their Geocaching Journey!  Geocaching is a treasure hunt that you can do alone or with your family using GPS coordinates.

How do we know if a stream is healthy?

-Take a look.  A healthy stream has what we call a riparian zone that is the interface between land and a stream.  The plants in these margins serve many functions from cleaning water to holding soil in place.  If we can work toward keeping the borders of streams protected from mowing, and ensure the plants are the types that benefit streams, we can do a lot to prevent flash floods and keep our streams healthier.

-What lives there?  Small animals who spend some part or all of their lives in creeks are what we call ‘indicator species’ because they’re easy to observe and differ in their ability to withstand pollution.

Invertebrates (lacking a backbone)

Since some benthic macroinvertebrates have high tolerance for pollution and handle it well, if those are most of what we find, we may have a less healthy water body.  A healthy stream will provide a place for wildlife to live.  It will have sounds and sights that confirm it supports an array of life in and around it.

test kit for water chemistry-Chemistry adds to the story.  Citizen Scientists and the professionals who study water test pH, conductivity and measure temperature.  They find out how much oxygen is in the water and send samples of water to labs to test for bacteria and chemicals.  Here in Lexington, you can be one of the citizen scientists helping to collect this information.  Email us if you would like to know how.
