Cossatot River — Daily Analysis: 2026-03-11

Classification: no_prediction Confidence: No prediction event provides observational data but no model performance feedback; confidence levels remain unchanged

Event Summary

Light rainfall (0.42 inches total) produced a modest 0.18 ft rise with very broad hydrograph shape, but no prediction was generated to evaluate.

Analysis

This event featured light, distributed rainfall across all bands with totals ranging from 0.42" in Band 1 to 0.51" in Band 5. The gauge confirmed 0.3" of precipitation, validating the QPE data quality. The resulting hydrograph showed a very broad 12-hour rise of only 0.18 ft, consistent with the light rainfall amounts and NORMAL moisture conditions. The broad shape suggests contributions from multiple bands with overlapping timing, which aligns with the relatively uniform spatial distribution of rainfall. Since no prediction was generated, there is no model performance to evaluate, but the observed response provides valuable calibration data for future light rainfall events. The response rate of approximately 0.43 ft/inch (0.18 ft rise ÷ 0.42" Band 1 rainfall) is reasonable for NORMAL moisture conditions and light intensity, falling between the dry headwaters response (0.26 ft/inch) and wet near-gauge response (2.08 ft/inch) from the seed events.

Coefficient Adjustments

No changes made.
