July 27, 2004: Scott Lennox reported on his water test results. He and his daughter Mandy took measurements on July 27, 2004 at 8:30 AM. The sky was overcast, wind was 0 MPH, outside temperature was 17.5 C and the water depth at the sample point was 7.25 meters.
Secchi Disk reading: 6.05 meters.

Report from Scott Lennox:
Periodic testing of the lake occurred from June to October with results consistent with the findings from previous years. Where our observations differed from 1998, they tended to be slightly improved.
The annual summer temperature stratification began to develop in June and was fully developed by July. Our July 30 testing provided a surface temperature of 26 degrees C (80 degrees F) and a 6.5 meter (21 feet) temperature of 20 degrees C (68 degrees F). This effect had disappeared with our last measurements in October. Our July water samples indicated correspondingly reduced levels of dissolved oxygen at each deeper level again consistent with or slightly better than 1998 levels. Our final monitoring revealed that the summer stratification had completely disappeared and we obtained a uniform temperature and level of dissolved oxygen.
Our Secchi disk monitoring of water clarity provided results that varied from typical 5.9 meters (19.5 feet) in July to an impressive 7.45 meters (24.5 feet) in October. This is significant because we conduct our testing in the deepest part of the lake (25 feet), and, as such, this measurement is likely to represent the top end of our potential results. One partial explanation for the improved results lies in the use of our new improved viewing scope, provided to us by the Maine DEP during our re-certification program. Secchi disk testing must be done with both scopes and reported to the Maine DEP separately. The use of the new scope can improve results up to 0.3 meters.
As with last year, these results compare favorably to the findings of prior years as far back as the mid 1980s. While the weather was above normal in warmth and brightness during the summer, the spring and fall also experienced significant storms and resulting runoff. Despite this, the test results, particularly in September and October, were among our best ever.
