1Volumetric discharge measurement.

2Tongue in the Kayenta Formation.

3Discharge measured at water-quality sampling site and at a different point than the measurement in 1952.

4Flume discharge measurement.

5Discharge measured at a different point than later measurements.

6Discharge measured in an irrigation ditch about 0.25 mile below water-quality sampling point.

7Discharge measured at water-quality sampling point about 20 feet below upper spring on west side of canyon.

8Discharge is approximate because the container used for the volumetric measurement was not calibrated.
