My meeting with Mike Wilson yesterday was fruitful. He gave me the rundown on the bioswale (the stream on the NW corner of campus), and on Corcoran Pond.
Interestingly enough, where the stream pops out below the lower soccer field is officially the headwaters of Johnson Creek North.
Two possible directions I could go with this information:
1. Track the course of the water that will become JCN, take nitrate/CO2/O2/other measurements as well as look at what kind of macroinvertibrates are present at different points in the stream's course.
Potential spots for sampling:
1. grate above upper soccer field
2. headwater below lower soccer field (check for leaching of liquid nitrate fertilizer from fields)
3. bioswale on the far corner of campus
4. stream near the Hursts' house
-note: Mike said he has maps of the watershed and that those will be able to tell me the course the stream takes
2. Test what kind of environment Corcoran Pond is
It is a collapsed lava tube lined with pond liner (not permeable by water), and is only filled by runoff and rainwater. It doesn't drain anywhere, except when the water level gets up higher than the liner and soaks into the surrounding soil.
Because of this, there is probably some interesting stuff going on with the compounds/chemicals that have washed in there over the years and been concentrated by evaporation.
I have more notes in my lab book, mostly specifics about the two ideas. Now that I have it narrowed down, I'll just need to decide whether to do number 1 by itself or add in number 2 as a smaller side experiment.
