Evaluating an aquatic ecosystem is a complicated process. Critical metrics used to evaluate any aquatic ecosystem include the species present and species abundance. Poor collection techniques or inaccurate identification can skew the results and jeopardize an entire project. Let the skilled WMS team plan and execute this important data collection for you. We have the equipment needed and the expertise to run the project correctly. WMS is authorized by Texas Parks and Wildlife to perform electroshocking and seining for aquatic and marine fish species, as well as aquatic and terrestrial insects. The permit is easily amendable and can be tailored to meet your needs through our experience and contacts within the agency. We have operated aquatic studies in numerous watersheds with varying project objectives. Below are a few examples of studies that we have completed.
Just a few examples of what we can do together:
- Biological Community Monitoring in the Cypress Creek BasinBiological Community Monitoring in the Cypress Creek BasinFor nearly a decade, WMS has been performing Aquatic Life Monitoring (ALM) studies in numerous tributaries of the Cypress Creek Basin, which is located in Northeast Texas. Big Cypress Creek is a major tributary to several reservoirs including Lake Bob Sandlin, Lake O’ the Pines, and Caddo Lake. The wetlands surrounding Caddo Lake have been designated as a “Wetlands of International Importance" under the Ramsar Convention. ALM studies include the collection and identification of fish and benthic macroinvertebrate species along with performing habitat assessments and taking water quality samples. All data are collected following approved protocols detailed in a Quality Assurance Project Plan (QAPP). The results of biological monitoring are used to determine if the stream is meeting its Aquatic Life Use stream standards designation.
- Biological and Habitat Monitoring of the East Fork Trinity RiverBiological and Habitat Monitoring of the East Fork Trinity RiverWMS performed diel monitoring, benthic and fish sampling, stream flow measurements, and habitat assessments at several stations in the East Fork of the Trinity River. The study reach was located below Lake Ray Hubbard and above the confluence with the main stem of the Trinity River. Multiparameter sondes were calibrated, deployed and programmed to record water quality parameters every fifteen minutes for a minimum of forty-eight hours. Stream flow, transect width, stream slope and other field parameters were recorded at each station along with performing an intensive habitat assessment throughout the entire reach. All monitoring was performed following Quality Assurance Project Plan approved protocols using TCEQ Surface Water Quality Monitoring procedures. This project was administered by the Trinity River Authority and the North Texas Municipal Water District. The results of the study were provided to the TCEQ Stream Standards Team to determine when NTMWD can withdraw water from the river for wetland treatment used to supplement their water supply.
- Fish Sampling and Bathymetry in Las Colinas, TexasFish Sampling and Bathymetry in Las Colinas, TexasIn order to calculate reservoir volume, WMS completed a bathymetric survey on three reservoirs and the canal system in Las Colinas. A SonTek RiverSurveyor M9 with RTK GPS was used to obtain depth contours and high resolution position data. Fish sampling was performed in this system using experimental gill nets, minnow traps, and an electro-shocking boat. The fish were identified and enumerated to determine which species were present, calculate diversity, and calculate the biotic integrity of the reservoirs. Water quality data were also collected in the reservoirs and the canal system using multiparameter sondes. The sondes were calibrated and deployed over a 48-hour period, recording data at 15-minute intervals. Water quality profiles, transect widths, and other field parameters were also measured. All sampling was performed following QAPP-approved protocols using TCEQ SWQM procedures.
Data Evaluation/Stream Assessments
Large datasets can be intimidating. WMS is experienced in the evaluation of technical data and performing complex statistical analysis. We have worked with governmental and private entities and understand the complexities associated with water management projects and reporting requirements. Through collaboration, we can ensure quality information is used for form decisions and help protect our water resources into the future.
Just a few examples of what we can do together:
- TCEQ Clean Rivers Program TCEQ Clean Rivers ProgramFor the past decade, WMS has managed most of the tasks detailed in the TCEQ Clean Rivers Program (CRP) for the Northeast Texas Municipal Water District. Our responsibilities include collecting water quality and biological samples, writing Basin Highlights and Basin Summary Reports, submitting data to TCEQ for inclusion into SWQMIS database, developing work plans and writing Quality Assurance Project Plans. WMS attends and presents project information at stakeholder and Coordinate Monitoring Meetings. We attend and often provide training to TCEQ SWQM and CRP partners at state-wide meetings and workshops. Our responsibilities include reviewing and developing sampling programs to meet the requirements of the Lake O’ the Pines TMDL Implementation Plan and coordinated with TCEQ Region 5 in sample collection in order to reduce the cost of the program and prevent the duplication of sampling efforts.
WMS has authored CRP Basin Summary Reports for NETMWD and the Lavaca Navidad River Authority. In order to author the report, we perform a comprehensive review of all historical data including data from the TCEQ SWQMIS database. These data typically span over forty years of water quality monitoring conducted in the basin. Statistical trend analyses are performed on the data to identify water quality trends occurring in the watershed. Upon completion of the report, we present these findings to stakeholders, general public, as well as to technical staff.
- Recreational Use Attainability Analysis & Bacterial Assessment of Big Cypress, Hart and Tankersley CreekRecreational Use Attainability Analysis & Bacterial Assessment of Big Cypress, Hart and Tankersley CreekWMS played an integral role in the Bacterial Assessment and Recreational Use Attainability Analysis studies. WMS wrote the QAPP, installed and maintained staff gages and water level loggers, developed flow rating curves, provided data input and data management, and tracked the project for completeness and accuracy. WMS performed a bacterial source survey, an historical data review, and a Recreational Use Attainability Analysis of the watershed. We assisted with bacteria sample collections, made numerous public presentations on the data collected, and authored reports on the results of the Bacterial Source Survey, Recreational Use Attainability Analysis, Historical Data Analysis, and the sampling results of the study.
- Upper Trinity River Total Maximum Daily Load (TMDL)Upper Trinity River Total Maximum Daily Load (TMDL)WMS, along with Parsons Engineering Science staff, collected water and sediment samples in support of the Upper Trinity River TMDL for PCB in Fish Tissue project. We participated in all aspects of field sampling including scheduling crews, gaining access to sampling stations, and operating high volume water samplers. Water samples were collected for PCBs during both ambient and storm conditions throughout the watershed. WMS ensured that staff strictly followed QAPP and SWQM procedures as detailed in the work plan.
Accurately quantifying our water resources is crucial to the success of any water management program. Measuring flow or the hydraulic characteristics of a water body can be accomplished with a variety of meters with each being best-suited for specific applications. Don’t get caught upstream without a paddle! Let WMS provide you with equipment recommendations, site selection, and hydrologic studies planning. From irrigation canals, to streams, to rivers, WMS has years of experience measuring flow in a variety of conditions. Our expertise ensures that the data obtained are of the highest quality possible. With good data, good management decisions are possible! Below are just a few examples of the studies WMS has had the honor to perform for our clients. From tidal cycle to gain-loss studies, WMS can meet all of your hydrological measurement needs.
Just a few examples of what we can do together:
- Gain-Loss Study of the Lower Nueces RiverGain-Loss Study of the Lower Nueces RiverThe lower Nueces River is used to convey water from Choke Canyon Reservoir to Lake Corpus Christi which serves as the water supply for the City of Corpus Christi. Preliminary data and computer models estimated that a significant percentage of water was being lost in this reach, enough that the construction of a pipeline could be justified. WMS was contracted to perform a gain-loss study on the lower Nueces River near Three Rivers, Texas. WMS strategically selected site locations, and measured discharge using the SonTek FlowTracker at wadeable stations and the SonTek RiverSurveyor M9 at non-wadeable locations. Flow measurements were made over the course of several weeks. Rainfall and groundwater levels were also recorded throughout the watershed. WMS identified areas of losses and determined that once the alluvium filled to a level that the losses in the river became minimal. These findings saved the City of Corpus Christi millions of dollars in pipeline construction costs.
- Hydrological Study of South Concho River BasinHydrological Study of South Concho River BasinDue to questions about the amount of water lost in the South Concho River, WMS performed a gain-loss study of the South Concho River watershed for the TCEQ Water Master. The study was conducted in order to quantify the amount of water lost in the South Concho River between the release at Lake Nasworthy and its confluence with the North Concho River. The study was also conducted to locate possible sources of water loss (both natural conditions and illegal pumping). As a result of the study, WMS made recommendations for future studies and identified site locations for the installation of continuous water monitoring stations that will best assist the TCEQ Water Master in making decisions about releases.
- Hydrographical Survey and Tidal Cycle Flow MonitoringHydrographical Survey and Tidal Cycle Flow MonitoringTo provide the data needed to calibrate a hydrodynamic model, WMS measured discharge in a channel between Sweetwater Lake and Galveston Bay through several tidal cycles. A SonTek RiverSurveyor M9 with RTK GPS was used to provide depth profiles and high resolution position data of the channel. Stream flow was measured every half hour, throughout two complete tidal cycles across different seasons. Hourly stream flow measurements were made in a wade-able cross-section of the channel using a SonTek FlowTracker acoustic Doppler velocimeter to verify data obtained by the M9. A SonTek Argonaut SW was also installed in the channel to provide continuous water velocity and level data at the cross-section. WMS installed a pressure transducer and staff plate to record water level at a secondary station as secondary reference.
Bathymetry & Volume
Reservoir storage capacity and sediment loading are serious concerns and it is important to know if a water source is as plentiful as it needs to be to support our growing communities. Human activities like construction and industrial processes contribute to sediment loading and can quickly reduce storage capacity.
WMS has contracted with municipalities and prominent consulting firms to perform bathymetric and volumetric studies using an acoustic Doppler profiler. These data are used to make capital intensive decisions like dredging or putting limited resources into other activities. The highest quality data can help support the decisions being made in today’s complex world. WMS will either collect the data for you to analyze or provide a full report.
Just a few examples of what we can do together:
- Lake Bathymetry, Dissolved Oxygen and Nutrient Monitoring of Grapevine LakeLake Bathymetry, Dissolved Oxygen and Nutrient Monitoring of Grapevine LakeWMS performed a bathymetric survey of six coves in Grapevine Lake using a SonTek RiverSurveyor M9 with RTK GPS. WMS staff performed diurnal monitoring in these coves and collected nutrient and chlorophyll samples at four stations in Grapevine Lake. Twelve YSI multiparameter water quality sondes were also deployed in coves at Grapevine Lake, Lewisville Lake and Lake Ray Roberts. The sondes recorded dissolved oxygen, pH, conductivity and temperature every fifteen minutes for a minimum of 24 hours. Water quality profiles, transect widths, secchi depth and other field parameters are recorded along with observational data. All sampling was conducted following QAPP-approved protocols described in the TCEQ SWQM procedures manual.
- Bathymetry and Volumetric Study of Lake Sulphur SpringsBathymetry and Volumetric Study of Lake Sulphur SpringsLake Sulphur Springs was constructed in 1973 to serve as the primary water supply for the City of Sulphur Springs and surrounding communities. Since the completion of Lake Jim Chapman Reservoir, the reservoir now serves as a backup water supply. Due to concerns about the effects of sedimentation on storage capacity, WMS was contracted to measure the volume of the reservoir. WMS staff conducted a site survey in order to select measurement transects. A SonTek RiverSurveyor M9 with RTK GPS tethered to a Jon boat was used to profile depth and position throughout the reservoir. Data were then compiled to calculate total volume and generate a depth contour map.
