Economic evaluation of activities associated with invasive mussel management
What is the cost effectiveness of prevention and control mussel management strategies? In the case of invasive mussels, prevention efforts to contain their spread rely on watercraft inspections and decontamination (WID). This effort is costly and is subject to concerns regarding efficacy. Once an infestation occurs, control of mussels to mitigate infrastructure impacts rely on reactive techniques to reduce interior mussel biofouling at hydropower or water delivery facilities. These efforts are also costly with regard to the O&M of the facility and the water and power users of that facility. This project aims to understand the cost effectiveness of these two types of management activities (prevention and control) in order to better utilize limited funds for quagga mussels management.
Need and Benefit
NEED: Reclamation continues to face a spectrum of issues with invasive mussels, and resources for management are limited. Current prevention and control methods have not been examined thoroughly for cost efficacy, and best usage of resources for invasive mussel management are not well understood.
The project will provide Reclamation leadership additional tools for decision making and efficient resource allocation. This economic analysis will provide additional metrics for determining an ideal mussel management approach and assist in understanding the costs in a Reclamation-wide approach. This project will potentially save taxpayer dollars, reduce O&M costs, and diminish the spread and impact of invasive mussels in the West through an understanding and development of cost-efficient practices.
Reclamation will continue to fund activities in a piecemeal approach that may not be the most cost effective or yield the most benefit in reducing the spread of invasive mussels.
