Some thoughts

Hi Laura:

I like this. You might want to look at nitrate-nitrogen or phosphorus in the stream above and below farm fields to see what effect land use has on water quality. Since changes across agricultural land will probably depend on season and on time of fertiler application, you might want to select several sampling dates---in the winter and in the spring. See Standard Methods For Water And Wastewater Analysis before you decide which analytical methods you will use.

I think you will find a large and varied literature on this subject so it will be useful to compare 4-Mile with other systems.

Also, from the perspective of aesthetics, it would be worth knowing how nutrients affect the appearance and value of natural waters and whether you can visually detect changes in water quality as the stream traverses farm land.
