Fuel Status (as of 17:35):
Diesel:
Approximate Reading: 3/4

Notes/Comments:
read the diesel level in the 500-gal tank using the gauge

Propane Tank:
Approximate Reading: 76% (760 gallons = 2876.9 L)

Gasoline:
Quantity Remaining: 55 gallons = 208.2 L [ -3 gallons since yesterday ]

Notes/Comments:
5 gallons are present in the jerry cans after refilling the ATVs. ~1
gallon has been removed from the drum since crew 67 departed.

Oil:
GenSet Quantity: 9 quarts [ no change since yesterday ]
ATV Quantity: 12 quarts [ -2 quarts since yesterday ]
[*] V'ger Quantity: 0 quarts

Notes/Comments:
V'ger offsite

Water Status:
Outside Potable Water Tank Level: 375 gallons = 1419.5 L
Trailer Potable Water Tank Level: 22 inches from the base
Potable Water Meter Reading: 26366 gallons = 99805.9 L
[ +40.4 gallons since yesterday ]
Out to Toilet Meter Reading: 8203 gallons = 31051.6 L
In to GreenHab Meter Reading: 7823.0 gallons = 29613.2 L
[ no change since yesterday ]
Dishwasher Runs: 0

Notes/Comments:
we located the "out to toilet" gauge for the TST under the trickle
tanks (the other meter is marked "in to greenhab" in green marker on
the meter cover); both are on the floor in the greenhab. As Chris found
on 3/1, the flow of potable water from the outside tank was minimal
when pumping attempted around 1 PM, but we were able to fill the
internal tank. Plan to try pumping later in the day next time (since
this time seemed to work better for crew 67).

GreenHab:
[*] Crops Watered: no

Crop Condition:
We added some potting soil and gently agitated the soil in the plant
boxes to aerate them. Due to questions about pumping potable water, we
did not water the plants today. However, since the internal tank is now
full (after 1 PM), we plan to water the plants tomorrow mid- or late
morning rather than late in the day today to avoid causing frost in the
boxes.
