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 WY2018 (October 2017–September 2018). The data analyses include: 1) monthly and annual WY2018 precipitation amounts at all 25 raingage sites, 2) WY2018 precipitation amounts compared to the previous 28-year network average pattern (WYs 1990–2017), and 3) the 29-year network precipitation average for WYs 1990–2018. Also included are raingage site descriptions, instructions for raingage technicians, and documentation of raingage maintenance and high storm totals.
