“…Similar to Five Blue Lake National Park, Floridian lakes Jackson and Scott have also experienced draining due to sinkhole activity (Penson, 2002;McBride et al, 2011). Various water budgets calculated by USGS investigators in karstic areas, like Florida, have helped researchers to better understand water movement and seasonal variability (Dalton et al, 2004;Spechler, 2010;McBride et al, 2011;Sepú lveda et al, 2012). This case study presents a water budget that combines the approaches used by Dalton et al, Spechler, and McBride et al, but was applied to capture a signature of the Rome Formation limestone aquifer in the Ridge and Valley Province of northwest Georgia.…”

“…More specifically, the great seasonal variability of lakes' water budgets tied to the Florida aquifer and the repercussions to surrounding communities has been the focus of recent United States Geological Survey investigations (Dalton et al, 2004;Spechler, 2010;McBride et al, 2011;Sepú lveda et al, 2012). The research conducted at Lake Seminole (Dalton et al, 2004) provided the framework for the water budget completed in this study. Dalton lists the challenges to measuring evaporation or evapotranspiration over a hydrologic year and emphasizes the importance of it as a driver in seasonal lake volume.…”

“…Previous studies have indicated the usefulness of creating water budgets for lakes in karstic terrains (Dalton et al, 2004;McBride et al, 2011;Aurit et al, 2013).

“…The complexity and the amount of data needed, such as windspeed, humidity, and solar radiation for these methods varies greatly. Dalton et al (2004) and Rosenberry et al (1993) determined that the energy-budget method was 8 to 26% more reliable than empirically derived equations and ultimately provided the best match if raw data are unavailable.…”

“…It appears that the preference in how evaporation is measured depends on the amount of data available or the amount of time and money a study has to commit. Using Class A pan evaporation measurements and Georgia Automated Environmental Monitoring Network (GAMEN) data as controls, Dalton et al (2004) evaluated six different methods of calculating lake evaporation rates. The complexity and the amount of data needed, such as windspeed, humidity, and solar radiation for these methods varies greatly.…”

Sinkholes and a Disappearing Lake: Victory Lake Case Study

Human-induced sinkhole collapse can result in drastic changes to landscape aesthetics and present challenges to land managers seeking to determine the plausibility of restoration, the amount of financial investment needed, and the long-term sustainability of tampering with karstic environments. Alteration of groundwater flow in a karstic environment expedited the formation of large sinkholes in the southern end of man-made Victory Lake, causing it to drain immediately. Soon after the lake emptied in 1986, two unsuccessful attempts were made to restore the 13 ha (32 ac) lake. The sinkholes formed in the southern basin were completely in-filled, eliminating 3 ha (8 ac) of lake basin and significantly altering the original lake morphology. Some twenty-seven years later, Victory Lake is holding some water in the shallow basin at the northern end and would primarily be classified as a marshy wetland. This study was initiated to investigate the current relationship between the groundwater and surface water at the lake's altered basin to determine the potential for it to be restored fully or partially as a recreational focal point of the Berry College campus. Over the course of one year we measured the inputs (stream flow and precipitation) and outputs (evaporation and surface water outflow) of the lake system. We were able to conclude that groundwater is not likely contributing to the lake, based on inorganic and stable isotope ( 18 O and 2 H) water chemistry analysis and the deep position of the groundwater table relative to the lake bottom. From the results of dye-tracer tests conducted in the lake, we concluded that basin water may not be escaping downward at measurable rates because of its clay bottom. Our overall water-budget analysis confirms an adequate water volume entering by rainfall and ephemeral stream inflow; nearly 90% of the water leaves Victory Lake through surface-water outflow. Water loss through evapotranspiration during spring and summer months overcomes the gain accomplished during wetter and cooler months, particularly February. Through an investigation of water level records kept for campus monitoring wells from 1998 through 2012 we confirm that the groundwater table has stabilized and the immediate threat of new sinkhole formation is minimal. Restoration of Victory Lake to its original picturesque meeting spot may be possible through creative engineering strategies and project financing. However, we question the longevity of managing a karstic environment and consider the potential risks to infrastructure, groundwater, and human health should lake bottom failure occur again on campus.

Abstract:Lake eutrophication is a large and growing problem in many parts of the world, commonly due to anthropogenic sources of nutrients. Improved quantification of nutrient inputs is required to address this problem, including better determination of exchanges between groundwater and lakes. This first of a two-part review provides a brief history of the evolution of the study of groundwater exchange with lakes, followed by a listing of the most commonly used methods for quantifying this exchange. Rates of exchange between lakes and groundwater compiled from the literature are statistically summarized for both exfiltration (flow from groundwater to a lake) and infiltration (flow from a lake to groundwater), including per cent contribution of groundwater to lake-water budgets. Reported rates of exchange between groundwater and lakes span more than five orders of magnitude. Median exfiltration is 0.74 cm/day, and median infiltration is 0.60 cm/day. Exfiltration ranges from near 0% to 94% of input terms in lake-water budgets, and infiltration ranges from near 0% to 91% of loss terms. Median values for exfiltration and infiltration as percentages of input and loss terms of lake-water budgets are 25% and 35%, respectively. Quantification of the groundwater term is somewhat method dependent, indicating that calculating the groundwater component with multiple methods can provide a better understanding of the accuracy of estimates. The importance of exfiltration to a lake budget ranges widely for lakes less than about 100 ha in area but generally decreases with increasing lake area, particularly for lakes that exceed 100 ha in area. No such relation is evident for lakes where infiltration occurs, perhaps because of the smaller sample size.

Abstract:This article presents the characterization of the infiltration rate in the area known as 'Las Cañas' which is part of Las Tablas de Daimiel National Park, Central Spain. Available information was used for direct identification and while the results varied widely, it was proven that a functional dependence exists between the infiltration rate and the inundated area. After examining the structure of this dependence more closely, the most appropriate model was deemed to be a bilinear model. With these basic foundations, data from years 1997, 1998, 2003 and 2005 were used to identify the three parameters of the model. Highly satisfactory identifications were obtained. The model was then calibrated and the drying processes from 1996, 2000 and 2003 were simulated with considerable accuracy since the standard deviation was only 4 ha for a total of 400 inundated ha. The model was used to estimate the evolution that the inundated area would undergo after introducing contributions of treated sewage effluents. Even though it was assumed that the results would entail twice as many errors as the standard deviation, they did, however, allow us to provide a concise description of the behaviour of the system. Consequently, elements of judgement that highlight the advisability of the application of treated sewage effluents in Las Cañas, from a hydrological standpoint, were obtained.
