Remarks:
Rainfall recorded at three nearby rain gauges
was unusualy low during the 3 weeks preceding the
delineation (0.3 to 0.6 inch during Jan 11 to Feb
2), but rainfall prior to that was nearly twice the
normal amount (8 to 9 inches during Dec 10 to Jan 10). Since evaporanspi ration rates are low in
January, we assume "normal" hydrologic circumstances in the project area.

Describe Recorded Data (stream gauge, monitoring well, aerial photos, previous inspections), if available:
Remarks:
Rainfall recorded at three nearby rain gauges
was 0.5 to 0.7 inch during the two days preceding the delineation (Nov 11 to 12), but rainfall prior to
Nov 11 was unusualy low for the preceding 7
weeks: only 0.9 to 1.1 inch during Sep 24 to Nov 10 (https://www.cocorahs.org/). The site was
presumably drier than normal during the Nov 13 delineation, but most of the stream bed still carried visible flow.

Remarks:
Rainfall recorded at three nearby rain gauges
was unusualy low during the 3 weeks preceding the
delineation (0.3 to 0.6 inch during Jan 11 to Feb
2), but rainfall prior to that was nearly twice the
normal amount (8 to 9 inches during Dec 10 to Jan 10). Since evaporanspi ration rates are low in
January, we assume "normal" hydrologic circumstances in the project area.

Describe Recorded Data (stream gauge, monitoring well, aerial photos, previous inspections), if available:
Remarks:
Rainfall recorded at three nearby rain gauges
was unusualy low during the 3 weeks preceding the
delineation (0.3 to 0.6 inch during Jan 11 to Feb
2), but rainfall prior to that was nearly twice the
normal amount (8 to 9 inches during Dec 10 to Jan 10). Since evaporanspi ration rates are low in
January, we assume "normal" hydrologic circumstances in the project area.
