“…Previous work in the PPR documented variability in wetland-to-wetland and wetland-to-stream connectivity as surface water merges in low relief areas and/or wetlands fill and spill (Leibowitz and Vining 2003;Kahara et al 2009;Shaw et al 2013;Vanderhoof et al 2016), and sought to predict connectivity based on storage capacity and spill point elevation (Huang et al 2011b), temporal changes in surface-water extent (Rover et al 2011), and wetland vegetation and water chemistry (Cook and Hauer 2007). This study sought to move from the prediction of connections for individual wetlands to explaining variability in the abundance of such surface-water connections on a landscape scale.…”

“…This study sought to move from the prediction of connections for individual wetlands to explaining variability in the abundance of such surface-water connections on a landscape scale. The probability of hydrologic connectivity has been most commonly linked to the proximity or distance between depressional wetlands and streams (Tiner 2003;Kahara et al 2009;Lang et al 2012). Yet this study found that substantial variation in the mean Euclidean and flowpath distance to stream for VC and NCO wetlands between ecoregions makes it extremely problematic to identify VC wetlands based on distance alone.…”

“…As depressional wetlands are typically non-channel connected (Tiner 2003), surface-water connections with other water bodies are usually not continuous. Under wet conditions, however, many of these wetlands cyclically or episodically exchange or contribute water to other wetlands, open waters, and/or streams through temporary overland or shallow groundwater flows, unmapped ditches or channels, and/or the merging of wetland waters in low relief areas (Rains et al 2006(Rains et al , 2008Cook and Hauer 2007;Sass and Creed 2008;Kahara et al 2009;Wilcox et al 2011;McCauley et al 2015). During flood events or wet periods, depressional wetlands that become connected to streams or subsumed by lakes exchange water and materials, but may experience the temporary loss of wetland function until water levels recede (Junk et al 1989;Galat et al 1998;Mortsch 1998).…”

“…Substantial variation in surface-water extent in response to climate is well-documented within the region (Beeri and Phillips 2007;Zhang et al 2009;Niemuth et al 2010;Huang et al 2011a;Liu and Schwartz 2011). Changes to surface waters can result in variable wetland-to-wetland (Winter and Rosenberry 1998;Kahara et al 2009) and wetlandto-stream connectivity (Leibowitz and Vining 2003;Sass and Creed 2008;Vanderhoof et al 2016). Minimal research, however has sought to explain the abundance of wetlands that show variable surfacewater connections, or understand at a landscapescale how these wetlands consolidate and become connected to streams.…”

“…This metric has been quantified using variables such as feature density, area, proximity, and cohesion, (Kahara et al 2009) or distance to stream (Tiner 2003;Lang et al 2012;Lane and D'Amico 2016). However, most of these efforts have been theoretical and have not related dynamic spatial variables, such as distance, to changes in actual surface-water extent.…”

Ecosystem function in rivers, lakes and coastal waters depends on the functioning of upstream aquatic ecosystems, necessitating an improved understanding of watershed-scale interactions including variable surface-water flows between wetlands and streams. As surface water in the Prairie Pothole Region expands in wet years, surface-water connections occur between many depressional wetlands and streams. Minimal research has explored the spatial patterns and drivers for the abundance of these connections, despite their potential to inform resource management and regulatory programs including the U.S. Clean Water Act. In this study, wetlands were identified that did not intersect the stream network, but were shown with Landsat images to become merged with the stream network as surface water expanded. Wetlands were found to spill into or consolidate with other wetlands within both small (2-10 wetlands) and large ([100 wetlands) wetland clusters, eventually intersecting a stream channel, most often via a riparian wetland. These surface-water connections occurred over a wide range of wetland distances from streams (averaging 90-1400 m in different ecoregions). Differences in the spatial abundance of wetlands that show a variable surface-water connection to a stream were best explained by smaller wetland-to-wetland distances, greater wetland abundance, and maximum surface-water extent. This analysis demonstrated that wetland arrangement and surface water expansion are important mechanisms for depressional wetlands to connect to streams and provides a first step to understanding the frequency and abundance of these surface-water connections across the Prairie Pothole Region.

Geographically isolated wetlands, those entirely surrounded by uplands, provide numerous landscape‐scale ecological functions, many of which are dependent on the degree to which they are hydrologically connected to nearby waters. There is a growing need for field‐validated, landscape‐scale approaches for classifying wetlands on the basis of their expected degree of hydrologic connectivity with stream networks. This study quantified seasonal variability in surface hydrologic connectivity (SHC) patterns between forested Delmarva bay wetland complexes and perennial/intermittent streams at 23 sites over a full‐water year (2014–2015). Field data were used to develop metrics to predict SHC using hypothesized landscape drivers of connectivity duration and timing. Connection duration was most strongly related to the number and area of wetlands within wetland complexes as well as the channel width of the temporary stream connecting the wetland complex to a perennial/intermittent stream. Timing of SHC onset was related to the topographic wetness index and drainage density within the catchment. Stepwise regression modelling found that landscape metrics could be used to predict SHC duration as a function of wetland complex catchment area, wetland area, wetland number, and soil available water storage (adj‐R 2 = 0.74, p < .0001). Results may be applicable to assessments of forested depressional wetlands elsewhere in the U.S. Mid‐Atlantic and Southeastern Coastal Plain, where climate, landscapes, and hydrological inputs and losses are expected to be similar to the study area.

Above-average precipitation in the 1990s resulted in many new fisheries across northeastern South Dakota and elsewhere in the Upper Midwest. Walleye Sander vitreus populations in these new fisheries can be extremely vulnerable to angler harvest. In an attempt to maintain a Walleye fishery in Reetz Lake, South Dakota, a new lake, a restrictive regulation of one Walleye ≥711 mm TL per day was implemented when the lake opened to public fishing (October 2001). To evaluate the regulation, we monitored the estimated number of Walleyes ≥508 mm, Walleye gillnet catch per unit of effort (CPUE) of stock-length fish (≥250 mm), size structure, condition, length at age at capture (ages 2-5), mortality, recruitment, and angler use during the period 2001-2019. The estimated number of Walleyes ≥508 mm, gill-net CPUE, and proportional size distribution of preferred-length fish (PSD-P; ≥510 mm) trended higher across years. Relative weight (Wr) for the quality-preferred (380-509 mm) and preferred-memorable (510-629 mm) length-groups and the length at age at capture for ages 4 and 5 trended lower. Walleyes <510 mm were in better condition than larger fish throughout the study. Estimated total mortality was 62% in 2004 but substantially declined in subsequent years before ranging from 6% to 21% for 2010-2019. The coefficient of variation of age-3 gill-net CPUE by cohort was 93%, indicating variable recruitment. Decreasing trends in Wr and growth were not surprising, as Walleye CPUE increased through time. Lengths at age remained at or above statewide and national averages. The values for number of angler-hours and Walleye catch rates were high during the summer months when most anglers targeted Walleye. The regulation that restricted harvest at Reetz Lake to one Walleye ≥711 mm allowed an abundant Walleye population to establish and was successful at maintaining the fishery in terms of abundance, size structure, and angler use. Water level fluctuations in lacustrine systems are primarily controlled by local and regional climate conditions that can last for decades or longer (White et al. 2008). Thus, precipitation patterns on the plains of the Upper Midwest can alter the number of Walleye Sander vitreus fisheries. During periods of above normal precipitation, semipermanent wetlands (i.e., "new lakes") form due to the inundation of low-lying areas and expansion of temporary wetlands. In South Dakota, the number of semipermanent wetlands increased in number by 76% and in area by 185% between periods of average precipitation (1979-1986) and above-average precipitation (1995-1999),
