Instream Flow

Instream Flow Incremental Methodology Studies

Water supply and hydroelectric plant operators are often required to identify flow targets that balanced aquatic community habitat with other water management issues such as reservoir level targets, power generation, and recreational boating and angling. During a project relicensing, the U.S. Fish and Wildlife Service, National Marine Fisheries Service, state governments, and Non-Governmental Organizations (NGOs) may request an Instream Flow Incremental Methodology (IFIM) study to evaluate the costs and benefits of providing alternate flows.

Kleinschmidt’s team routinely leads IFIM study aspects including:  collaborate interagency study teams to identify all flow related issues, focus the study scope on applicable parameters, define evaluation criteria, locate study sites and transects, gather survey and hydraulic data, develop hydraulic and habitat models, analyze model output, and prepare written reports and analyses. 

Our team will work closely with both the operator and all interested stakeholders to successfully select flows that meet all objectives. Results of the model and its recommendations are incorporated into a project’s FERC license application, and also adopted as a tool to support other flow assessment issues in a particular river basin.
