Abstract:

Water scarcity in the United States is becoming increasingly common, especially in arid and semi-arid locations. The current conditions under which water is allocated from the Colorado and Yampa Rivers are shifting in a direction of depletion. A unique facet of water resource management in Colorado is the Colorado Water Court, a specialized court dedicated to resolving water resource issues between water rights holders; only Montana and Idaho have similar systems. This court employs experts in hydrologic science and trains judges so that they are able to make informed decisions. This project aims to analyze the legal system’s response to finite resource allocation and depletion using the Colorado Water Court system as a case study to analyze the intersection of the two fields. In 2021, the Yampa River was classified as over appropriated, precipitating water shortages across the state. However, these water shortages coincide with ongoing negotiations regarding the expiration of the Compact’s guidelines and the subsequent reassessment of allocated water to the upper and lower basins. This discussion presents an opportunity to audit the legal and federal bodies involved in the process of water allocation in the state, namely the Colorado Water Court system. Understanding the dynamics between this specialized court and the water users that live along the Yampa River allows for a realistic assessment of operational improvements in both legal and hydrological aspects. 

In this project, I combine an analysis of existing literature with direction from local stakeholders, including ecological organizations and professors. Those closest to the water body are best positioned to identify the important factors that directly affect water use, quality, and allocation as it exists today.  Preliminary results suggest that the water court system does not have a significant presence on the ground despite the repercussions of its decisions. This disconnect illustrates the dynamics between federal and local stakeholders in the water resources sector. As one of the last existing wild rivers in the West, the Yampa is relied upon across multiple levels of society: the seven states written into the Colorado River compact, Colorado residents, and those living along the Yampa River.
