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, the operations and maintenance procedures, the data reduction and quality control methodology, and an analysis of precipitation for Water Year 2015 (October 2014–September 2015). The data analyses include: 1) monthly and Water Year 2015 amounts at all sites, 2) Water Year 2015 amounts compared to patterns from network Water Years 1990–2014, and 3) the 26-year network precipitation average for Water Years 1990–2015. Also included are raingage site descriptions, instructions for raingage technicians, documentation of raingage maintenance, and documentation of high storm totals.
