The creek is a slow running creek, but the dissolved oxygen is quite low. Seeing as how we didn't get that many macros on Monday, the low oxygen content might mean that the bugs have headed for more fruitful places.

Creek Week Water Chemistry
Today the group measured dissolved oxygen in the creek. Each of the kids got to do part of the digital titration, and we measured between 4.5 and 5.0 mg of dissolved oxygen in twelve measurements over 4 samples. We also measured increasing temperature through the morning and a pH around 8.0. Conductivity was about 10 microsiemens.
