Archaeological Testing of the Lewisville Lake Shoreline, Denton County, Texas

Description: This report describes the results of test excavations at 23 prehistoric and 16 historic sites on the periphery of Lewisville Lake, Denton County, Texas. The purpose of this report is to summarize the character and significance of the archaeological sites that were test excavated and recommendations for mitigation at those sites determined eligible for the National Register.

Primary productivity and nutrient relationships in Garza-Little Elm reservoir

Description: A large, multi-basin reservoir (Garza-Little Elm Reservoir) in north central Texas was studied to determine the relative effects of various parameters on primary productivity. The basins were impounded several years apart, thus allowing the influence of age on water chemistry and biota to be considered. Another principal influence on water quality was secondary sewage effluent that entered one basin from a nearby source.

Technical Memorandum: Lewisville Lake Watershed Protection and Management Strategies

Description: With a current population of just over half a million and a 2030 projected population of approximately one million, expansion throughout Denton County shows no sign of slowing down (NCTCOG). Increasingly, freshwater resources are also facing increased pressure from this urban expansion. Effective assessment and management techniques are necessary to protect the diversity of ecosystem services found within fluvial ecosystems and to mitigate current and future conditions of environmental stressor amplified by urban development. The use of various spatial analysis techniques in environmental assessment present more expedient, cost effective, and broader ranging methods of evaluation than traditional field techniques. One such novel evaluation technique is the Water Quality Corridor Management (WQCM) model, developed by the University of North Texas in cooperation with the Upper Trinity Regional Water District (UTRWD). The WQCM model is a geospatial database that utilizes GIS and remote sensing techniques to assess and prioritize stream reaches according to their overall health and sustainability. This project assessed the viability of the WQCM model in reviewing the status of stream systems, and ultimately, established an accurate mechanism for evaluating the stream corridor and surface water quality draining into Lewisville Lake, a popular recreation site and drinking water source for the urbanizing Dallas and Fort Worth metropolitan area.

Water Quality Corridor Management for Restoration (WQCM-R) Modeling Dataset

Description: The dataset was developed to support research intended to develop a spatially-explicit model that prioritizes riparian areas in terms of potential for ecosystem restoration specifically to improve water quality downstream of the riparian area, and ultimately improve drinking water quality. The model was developed and then tested on the Lewisville Lake watershed (north central Texas, just north of Dallas, Texas, USA). The dataset contains environmental data for 90 sub-watersheds that form the overall Lewisville Lake watershed with a corresponding identification map.

Surface Water and Groundwater Hydrology of Borrow-Pit Wetlands and Surrounding Areas of the Lewisville Lake Environmental Learning Area, Lewisville, Texas

Description: The focus of this study was to characterize the surface water and groundwater hydrology of borrow-pit wetlands located within the borders of the Lewisville Lake Environmental Learning Area (LLELA), east of the Elm Fork of the Trinity River. The wetlands were excavated into alluvial deposits downstream of the Lewisville Lake Dam. Both surface water and groundwater contribute to the hydro-period of the borrow-pit wetlands. Nearby marshes exhibit characteristics of groundwater discharge. Salinity in groundwater-fed wetlands could affect establishment of vegetation, as suggested from plant surveys. Surface water input from storm events dilutes salinity levels. Management of LLELA wetlands should include long-term evaluation of hydrology and plantings to enhance habitat. Plans for additional wetlands should consider both surface water and groundwater inputs.
