Condition Assessment Needs for Prioritizing Small Dam Removal
There are large numbers of aging dams located throughout the United States. For example, there are currently 857 dams in the State of Washington under the jurisdiction of the Dam Safety Office and over 2,400 dams in the state of Michigan. Many of these dams no longer serve their intended purpose and will continue to deteriorate until such time as they will ultimately fail. The consequences of dam failure may involve substantial downstream injury and property damage as well as catastrophic and long-lasting environmental effects. Many dams are already detrimental to fish migration and may have significantly altered the downstream sediment budget causing changes in habitat characteristics. As a result, many State Agencies and environmental groups are considering dam removal opportunities. However, it is difficult to rapidly and accurately prioritize a large inventory of candidate dams based on the various and divers factors influencing the significance of each removal project. This paper presents a framework for the use of an indexing technique to prioritize the removal of small dams over a large inventory of dams. This framework is not meant to dictate protocol, but rather to stimulate discussion and awareness of the many trade-offs involved in the decision to remove a dam. The adoption of a prioritization methodology is required to use limited resource dollars efficiently.
