Richland Creek — Daily Analysis: 2026-04-30

Classification: no_prediction Confidence: Model confidence remains unchanged as this non-rainfall event provides no calibration information

Event Summary

The gauge showed a minor 0.38 ft rise with zero recorded precipitation across all bands, indicating either measurement noise or a non-rainfall hydrologic event.

Analysis

This event presents a puzzling scenario where the gauge recorded a 0.38 ft rise from 2.32 ft to 2.7 ft over 0.5 hours with zero precipitation recorded by both the gauge sensor and QPE data across both watershed bands. The sharp hydrograph shape suggests a localized input, but the complete absence of rainfall data makes this likely a measurement artifact, equipment malfunction, or possibly a non-rainfall event like groundwater discharge or upstream human activity. Since no prediction was generated due to the lack of rainfall input, there is no prediction accuracy to evaluate. The gauge readings remain well below the too_low threshold of 3.0 ft, so this represents minimal hydrologic significance. Without any rainfall data to correlate with the observed rise, this event provides no useful information for calibrating the rainfall-runoff relationship coefficients.

Coefficient Adjustments

No changes made.

Notes

Model confidence remains unchanged as this non-rainfall event provides no calibration information
