“…The earliest instance of this separate treatment in United States (U.S.) jurisprudence was in 1861 when the Ohio Supreme Court declined to intervene in a dispute where a surface water user was impacted by a groundwater pumping neighbor (Klein, 2022). While regulatory actions and legal rulings in recent decades address streamflow depletion in jurisdictions including California (Owen et al., 2019), Europe (Kallis & Butler, 2001), Australia (Ross, 2018), and India (Harsha, 2016), most groundwater management plans still do not address streamflow impacts of groundwater pumping (Gage & Milman, 2020), despite documented impacts of pumping on surface water users and ecosystems (Currell, 2016; Perkin et al., 2017; Zipper, Popescu, et al., 2022).…”

Reductions in streamflow caused by groundwater pumping, known as “streamflow depletion,” link the hydrologic process of stream‐aquifer interactions to human modifications of the water cycle. Isolating the impacts of groundwater pumping on streamflow is challenging because other climate and human activities concurrently impact streamflow, making it difficult to separate individual drivers of hydrologic change. In addition, there can be lags between when pumping occurs and when streamflow is affected. However, accurate quantification of streamflow depletion is critical to integrated groundwater and surface water management decision making. Here, we highlight research priorities to help advance fundamental hydrologic science and better serve the decision‐making process. Key priorities include (a) linking streamflow depletion to decision‐relevant outcomes such as ecosystem function and water users to align with partner needs; (b) enhancing partner trust and applicability of streamflow depletion methods through benchmarking and coupled model development; and (c) improving links between streamflow depletion quantification and decision‐making processes. Catalyzing research efforts around the common goal of enhancing our streamflow depletion decision‐support capabilities will require disciplinary advances within the water science community and a commitment to transdisciplinary collaboration with diverse water‐connected disciplines, professions, governments, organizations, and communities.

“…A review of 54 groundwater management plans in the U.S. found that only six (11%) had quantitative targets related to streamflow depletion (Gage and Milman 2020), and there are many regions around the world where streamflow depletion is not addressed by water management. In India, for example, groundwater and surface water are typically managed separately (Srinivasan and Kulkarni 2014;Harsha 2016), and therefore "groundwater use is not considered to be linked to streamflow and is decoupled from the surface water allocation" by water management groups (Biggs et al 2007). Even where new regulations and policies are made to address the interconnected nature of groundwater and surface water, there can be legacy effects of a different or unregulated past that adversely impact water resources (Owen et al 2019).…”

“…Data-driven approaches to surrogate modeling, also referred to as "metamodeling," train statistical models on the input and output data from numerical models and then use the simpler statistical models for scenario assessment. Metamodels have recently emerged in the groundwater community and can be incorporated into decision support systems for streamflow depletion scenario analysis (Fienen, Nolan, et al 2015, 2016Starn and Belitz 2018). However, both of these surrogate modeling approaches are still only feasible in locations where numerical models already exist.…”

Groundwater pumping can cause reductions in streamflow (“streamflow depletion”) that must be quantified for conjunctive management of groundwater and surface water resources. However, streamflow depletion cannot be measured directly and is challenging to estimate because pumping impacts are masked by streamflow variability due to other factors. Here, we conduct a management‐focused review of analytical, numerical, and statistical models for estimating streamflow depletion and highlight promising emerging approaches. Analytical models are easy to implement, but include many assumptions about the stream and aquifer. Numerical models are widely used for streamflow depletion assessment and can represent many processes affecting streamflow, but have high data, expertise, and computational needs. Statistical approaches are a historically underutilized tool due to difficulty in attributing causality, but emerging causal inference techniques merit future research and development. We propose that streamflow depletion‐related management questions can be divided into three broad categories (attribution, impacts, and mitigation) that influence which methodology is most appropriate. We then develop decision criteria for method selection based on suitability for local conditions and the management goal, actionability with current or obtainable data and resources, transparency with respect to process and uncertainties, and reproducibility.
