Peak-Flow Frequency Analysis for U.S. Geological Survey Streamgage 05481510 Bluff Creek at Pilot Mound, Iowa, in the Des Moines River Basin, Iowa, Based on Data Through Water Year 2021

January 10, 2023

This data release presents a peak-flow frequency analysis for U.S. Geological Survey streamgage 05481510 Bluff Creek at Pilot Mound, Iowa. The annual peak-flow record at this streamgage consists of both a discrete crest-stage period and a continuous partial-record period. The streamgage, which is in the Des Moines River Basin, is located on 130th Street in Pilot Mound, Iowa. Drainage area at the streamgage is 23.5 square miles. Annual peak-flow data are available for the period 1966-2021. The peak of record, 1,290 cubic feet per second, occurred on June 16, 1990. The annual peak-flow data used in the frequency analysis were downloaded from the U.S. Geological Survey National Water Information System database (U.S. Geological Survey, 2022) and the procedures for the flood frequency analyses are described in Eash and others (2013). The program PeakFQ version 7.4 was used for these analyses; a description of this program can be found in Flynn and others (2006) and Veilleux and others (2014).
