Research output: Book/Report/Conference proceedingTechnical report

Abstract

A dense raingage network has operated in Cook County since the fall of 1989 to provide accurate precipitation measurements for use in simulating runoff for Lake Michigan diversion accounting. This report describes the network design,operations and maintenance procedures, data reduction and quality control methodology, and an analysis of precipitation for WY2019(October 2018–September 2019). The data analyses include:1) monthly and annual WY2019 precipitation amounts at all 25 raingage sites, 2) WY2019 precipitation amounts compared to the previous 29-year network average pattern (WYs 1990–2018), and 3) the 30-year network precipitation average for WYs 1990–2019. The report also includes raingage site descriptions, instructions for raingage technicians, and documentation of raingage maintenance and high storm totals.
