Topock Marsh is a large wetland adjacent to the Colorado River and main feature of Havasu National Wildlife Refuge (Havasu NWR) in southern Arizona. In 2010, U.S. Fish and Wildlife Service (FWS) and Bureau of Reclamation began a project to improve water management capabilities at Topock Marsh and protect habitats and species. Initial construction required a drawdown, which caused below-average inflows and water depths in 2010-2011. Co-applicants Daniels and Haegele of FORT monitored Topock Marsh during the drawdown and immediately after, thus obtained information on immediate effects. However, stress from the drawdown may have a delayed effect on aquatic resources; additionally, significant changes to the infrastructure and water operations [...]

The overall goal of the project is to provide an assemblage of biotic, abiotic, and hydrologic data needed to better understand the health and function of the marsh under current conditions; and to develop a Decision Support System that provides an evidence-based scientific approach that will allow the Refuge to compare hydrological scenarios and evaluate their effects on habitats of concern based on priority management needs.
