Overview
Water stargrass (Heteranthera dubia) is a species of perennial aquatic plant in the Pontederiaceae family. It lives in freshwater such as lakes, rivers, and irrigation canals; preferring calmer waters.
In the Lower Yakima River, water stargrass is prolific in many stretches of the lower 47 miles, below Prosser Diversion Dam.
Studies
Multiple studies have been completed or are on-going on stargrass and the Lower Yakima River.
A 2009 report[1] by the USGS and Benton Conservation District detailed a 2004-2007 assessment of eutrophication in the lower 116 miles of the Yakima River. This was one of the first studies that characterized the proliferation of water stargrass in the Lower Yakima River. See PDF
A 2011 assessment of the Lower Yakima River includes a chapter on water stargrass[2]. See PDF
A 2020 Master's Thesis on water stargrass in the Lower Yakima River[3]. See PDF
The USGS and Benton Conservation District released a 2025 draft report on stargrass and water quality in the Lower Yakima River from 2018-2020 See PDF. The data is available on the USGS website, link.
