| Weather: The day started out cloudless and warm (about 90° F), but eventually turned into clouds and winds. The clouds weren't really noticeable until the second to the last site, but at the last site, it was very breezy and there wasn't any blue in sight in the sky. |

The air was cold and there were small consistent winds. Not the most pleasant day for swimming, but not so uncomfortable that it was unbearable to be outside. While at a few sites, there were some small showers, but while driving from place to place, there were sudden downpours. |

 |
| The following water quality parameters are measured at 9 sites in the Mary's River watershed: |
 |
| pH (Scale from 0-14 with 7 being ideal) Should be from 6.5 to 8.5. An OakTon pHTestr1 is what is used. |
|
| Temperature (Listed in Celsius ) Should be 17.8°C ( 64°F) for salmonid rearing.12.8°C (55°F) for waters during periods of native salmonid spawning, egg incubation, and fry emergence from the egg and from the gravels. The thermometer on the D.O. meter is what is used. |
| Turbidity; (How many solids are suspended in the water) Excessive turbidity is detrimental to aquatic life. The Oregon State water quality criteria requires that there shall be no more than a ten percent cumulative increase in natural stream turbidities measured relative to a control point immediately upstream of the turbidity causing activity. Turbidity is useful in monitoring stream sediment, its source, transportation, and deposition. A Hach 2100P Turbidimeter is what is used. |
| D.O.[Dissolved Oxygen] The State of Oregon water quality dissolved oxygen standards are as follows: for water-bodies providing for cold-water aquatic life, the DO shall not be less than 8.0 mg/L; for water-bodies providing for cool-water aquatic life, the DO shall not be less than 6.5 mg/L; and for water bodies providing for warm-water aquatic life, the DO shall not be less than 5.5 mg/L. A Hach DO175 D.O. meter is what is used. |
| E. coli [Escherichia coli] (Measured by both myself and the state; in colonies per 1ml) 406 organisms/100 ml for a single sample and 126 organisms/100 ml for a 30-day log mean based on a minimum of five samples. I will plate out E. coli at home and will also send water samples to be testedto the state lab. |
| Visibility Depth Depth is measured for those interested in swimming. A red and black checkered swimming pool visibility disk is what is used. |
| Other notes are taken concerning signs of human presence, weather and any other notes made at the site. |

Weather: Partly cloudy. A very different change from the three digit temperatures of last week. Notes: There was a sort of film that covered the surface of the Long Tom that was orange in color and stuck to the meters and skin. It came off the plastic fine, but I had difficulty rubbing it off my skin. When I touched the surface of the water, it cracked like an iceberg would instead of rippling out. I don't know what it was. |

| * At the state lab, 100 mL of the sample water is measured whereas I just plated out 1 mL of water at home. That is the reason for the huge difference between the two. Anything that is above 126 colonies per 100 mL is investigated by Ron Smith to see if anything might be amiss. |
 |
 |
| These are two pictures of the plates of E. coli that I incubated at home. Alsea Falls (left) had a low total coliform count whereas the Long Tom (right) had many more. Neither of these two plates contained any E. coli colonies on this date. |

| ** On August 19, by mistake, the courier service failed to transport these water samples to the state lab, so I have no E. coli results for this date but those that I plated out at home. On the September 2 date, I did not have enough materials to plate out all the sites, so I do not have data for that, but I hope to receive the state's results soon. |
| E. coli: In regards to the extremely high E. coli count, Ron Smith investigated this spike in the bacteria colonies on August 14, 2002 and measured a few more places in the area to find where the source of the high numbers might be. Here are his results: Site Fecal coliform cfu/100mL E. coli cfu/100mL 20' upstream from the boat ramp 46 24 60' upstream of Mill Creek inflo by brigde 42 28 Seepage on boat ramp 26 8 Fish Hatchery Road- N.
