“…For example, Kidmose et al (2013) found that low permeable lacustrine sediments can completely prevent groundwater upwelling, whereas Vainu et al (2015) observed LGD through low permeable lacustrine sediments. Kishel and Gerla (2002) associated small-scale variabilities in LGD with small-scale heterogeneities in hydraulic conductivities (Kishel and Gerla, 2002); Schneider et al (2005) found no correlation between seepage rates and sediment characteristics.…”

“…However, isotropic and homogenous conditions rarely exist and spatial distribution of groundwater inflow differs strongly from lake to lake . Experimental studies highlighted a large variety of observed exchange patterns including decreasing seepage with distance from the shoreline (McBride and Pfannkuch, 1975;Brock et al, 1982;Cherkauer and Nader, 1989;Kishel and Gerla, 2002), increasing seepage with distance from the shoreline (Cherkauer and Nader, 1989;Schneider et al, 2005;Vainu et al, 2015), local hotspots of offshore seepage (Fleckenstein et al, 2009;Ono et al, 2012) and a high smallscale variability in near-shore zones (Kishel and Gerla, 2002;Blume et al, 2013;Neumann et al, 2013;Sebok et al, 2013). Most often, complex hydrogeological settings are the reason for deviations from the theoretical pattern of LGD .…”

Two other methods have also been used successfully to investigate exchange patterns between lakes and groundwater: fibre-optic distributed temperature sensing (FO-DTS) (Blume et al, 2013;Sebok et al, 2013) and vertical temperature profiles (VTPs) (Blume et al, 2013;Neumann et al, 2013;Sebok et al, 2013).…”

“…The measurement of radon activities can also help to identify groundwater inflows (Kluge et al, 2012;Ono et al, 2012;Shaw et al, 2013). Existing lake studies have investigated LGD patterns with either a high spatial resolution (1-2 m 2 ) but a local focus (10 m × 17 m-25 m × 6 m) (Kishel and Gerla, 2002;Blume et al;Sebok et al, 2013) or focused on the entire lake but used a relatively low spatial resolution (measurements along the shoreline every 200-3000 m) (Schneider et al, 2005;Shaw et al, 2013). However, the experimental effort required rarely allows their extension to cover the lateral, alongshore dimension in sufficient extent and detail to identify the spatial variability and patterns of LGD along the shoreline.…”

Abstract. Lacustrine groundwater discharge (LGD) can significantly affect lake water balances and lake water quality. However, quantifying LGD and its spatial patterns is challenging because of the large spatial extent of the aquiferlake interface and pronounced spatial variability. This is the first experimental study to specifically study these largerscale patterns with sufficient spatial resolution to systematically investigate how landscape and local characteristics affect the spatial variability in LGD. We measured vertical temperature profiles around a 0.49 km 2 lake in northeastern Germany with a needle thermistor, which has the advantage of allowing for rapid (manual) measurements and thus, when used in a survey, high spatial coverage and resolution. Groundwater inflow rates were then estimated using the heat transport equation. These near-shore temperature profiles were complemented with sediment temperature measurements with a fibre-optic cable along six transects from shoreline to shoreline and radon measurements of lake water samples to qualitatively identify LGD patterns in the offshore part of the lake. As the hydrogeology of the catchment is sufficiently homogeneous (sandy sediments of a glacial outwash plain; no bedrock control) to avoid patterns being dominated by geological discontinuities, we were able to test the common assumptions that spatial patterns of LGD are mainly controlled by sediment characteristics and the groundwater flow field. We also tested the assumption that topographic gradients can be used as a proxy for gradients of the groundwater flow field. Thanks to the extensive data set, these tests could be carried out in a nested design, considering both small-and large-scale variability in LGD. We found that LGD was concentrated in the near-shore area, but alongshore variability was high, with specific regions of higher rates and higher spatial variability. Median inflow rates were 44 L m −2 d −1 with maximum rates in certain locations going up to 169 L m −2 d −1 . Offshore LGD was negligible except for two local hotspots on steep steps in the lake bed topography. Large-scale groundwater inflow patterns were correlated with topography and the groundwater flow field, whereas small-scale patterns correlated with grain size distributions of the lake sediment. These findings confirm results and assumptions of theoretical and modelling studies more systematically than was previously possible with coarser sampling designs. However, we also found that a significant fraction of the variance in LGD could not be explained by these controls alone and that additional processes need to be considered. While regression models using these controls as explanatory variables had limited power to predict LGD rates, the results nevertheless encourage the use of topographic indices and sediment heterogeneity as an aid for targeted campaigns in future studies of groundwater discharge to lakes.

“…Akanuma Pool showed input seepage water of 1.0 mm day -1 through the bottom, on average, during the ice-free period of 2007 and 2008, resulting in greater input fluxes of chemical constituents. For pools that formed on alluvial lowland, groundwater usually flows into pools because alluvial lowlands are located on the groundwater discharge area (Brock et al, 1982;Schneider et al, 2005;Yamamoto, 1992).…”

Groundwater discharge into a seepage lake was investigated by combining flux measurements, hydrochemical tracers, geological information, and a telescopic modeling approach using first two‐dimensional (2‐D) regional then 2‐D local flow and flow path models. Discharge measurements and hydrochemical tracers supplement each other. Discharge measurements yield flux estimates but rarely provide information about the origin and flow path of the water. Hydrochemical tracers may reveal the origin and flow path of the water but rarely provide any information about the flux. While aquifer interacting with the lake remained under seemingly steady state conditions across seasons, a high spatial and temporal heterogeneity in the discharge to the lake was observed. The results showed that part of the groundwater flowing from the west passes beneath the lake and discharges at the eastern shore, where groundwater springs and high discharge zones (HDZs) are observed at the lake bottom and at seepage faces adjacent to the lake. In the 2‐D cross section, surface runoff from the seepage faces delivers 64% of the total groundwater inputs to the lake, and a 2 m wide offshore HDZ delivers 13%. Presence of HDZs may control nutrient fluxes to the lake.
