California lawyer Arthur L. Littleworth (b. 1923) served as Special Master on the Supreme Court case, Original No. 105, Kansas v. Colorado, et al., from 1987 until its conclusion in 2009. The case was tried in four parts, and Littleworth wrote five reports during the course of the case. The collection is nearly comprehensive in terms of the trial transcripts, exhibits, and pleadings which were part of the case. Additionally, drafts, trial notes, and reference files support the five reports which Special Master Littleworth wrote. Due to the nature of the case, most aspects of the Arkansas River and some of its reservoirs and tributaries are covered, including streamflow, groundwater wells, and the Arkansas River Compact. For more information see the finding aid.

This digital collection, with materials dated 1914 to 2009, consists of proceedings, trial transcripts, select exhibits, correspondence, pleadings, and working files from Kansas v. Colorado.
