“…Human population density is highest at the lower end of the reservoir, whereas the upper portion of the reservoir is sparsely populated and includes designated wildlife management areas. The reservoir also acts as a major source of drinking water for the City of Virginia Beach (Cox 2007).…”

In weed control plans that use Grass Carp Ctenopharyngodon idella for intermediate control of hydrilla Hydrilla verticillata, the knowledge of population dynamics improves efficacy of management. Our objective was to characterize growth, mortality, and associated population metrics of long‐lived (up to 16 years) triploid Grass Carp that were incrementally stocked into Lake Gaston, Virginia–North Carolina, starting in 1995. Grass Carp (ages 1–16) were collected by bowfishers during 2006–2010. Growth of Grass Carp was described by the von Bertalanffy growth model as Lt = 1,297[1 − e −0.1352(t +1.52)], where Lt is TL at age t. We used three methods to estimate Grass Carp mortality, and annual abundance and biomass of Grass Carp were estimated from each mortality estimate. Estimated annual mortality ranged from 0.20 to 0.25 depending on the method used. The use of constant mortality rates versus age‐specific mortality rates produced divergent models of Grass Carp biomass and represented a different approach for tracking the progress of weed control. Grass Carp biomass (but not abundance) was related to hydrilla coverage in Lake Gaston based on several scenarios that described time lags between Grass Carp stocking in year i and decreases in hydrilla coverage (in years i, i + 1, …, i + 5). Regardless of the mortality estimate used to derive Grass Carp biomass, the strongest biomass–hydrilla coverage relationship was observed for a time lag of 4 years. Fish older than age 10 constituted nearly 50% of the total Grass Carp biomass in Lake Gaston during some years, and the relationship between Grass Carp biomass and hydrilla coverage was strongest when fish up to age 16 were included in models. These results indicate that Grass Carp up to at least age 16 are important for weed control, thus highlighting the need for stocking models and bioenergetics models that include contributions of older fish when assessing long‐lived Grass Carp populations.Received January 23, 2012; accepted October 3, 2012

“…Additionally, conflicts have arisen over freshwater resources that form boundaries between states in the United States (Poff et al 2003). Water conflicts in the United States have been occurring for the past 80 or more years and are likely to increase as water becomes more limiting Q6 to growth and development (Cox 2007;Davis 2007;Dellapenna 2007;Phelps 2007). Currently, the majority of conflicts involving water have dealt with surface waters.…”

“…A protracted process of negotiations and legal actions began in the early 1980s when the City of Virginia Beach requested an allocation of storage in Kerr Lake to support a transfer of 227 km 3 /day from Lake Gaston for use as municipal water. All the issues were finally resolved in 2003 when the parties agreed to several conditions attached to relevant permits (Cox, ). Among the more significant conditions was a set of lower and upper bounds on releases from Kerr Lake during the period April 15 through June 15 to protect a highly valued striped bass spawning habitat in the Lower Roanoke River.…”

Relative Value of Water for Hydropower and Municipal Supply in Southeastern Reservoirs

Population growth in the Southeast has driven withdrawals for municipal water beyond the limits of local supplies. With few options left for development of virgin sources, a number of urban areas are looking toward demand management and additional supplies by reallocating storage in reservoirs that were built primarily or in part for hydropower. Hydropower has become a lesser part of the mix of energy sources, and the question arises as to value of water for that purpose relative to its value for municipal use. Three cases are used to examine the issue. Effects of withdrawal for municipal water supply on output of electric energy are estimated. Benefits of foregone energy are evaluated using the least cost alternative for replacement, and benefits for municipal water are estimated using costs for development of new sources. Benefits for use as municipal water are found to be considerably higher than benefits for hydroelectric energy at existing prices, even higher than the least cost alternative for replacement. Given the spatial distribution of the cases, that finding would appear to hold in general across the region.
