August 31, 2004 EXECUTIVE SUMMARY

Activities and Accomplishments

The Texas Legislature passed the Texas Clean Rivers Act (Senate Bill 818) in 1991. This Act established the Texas Clean Rivers Program (CRP) under the Texas Commission on Environmental Quality (TCEQ). The Northeast Texas Municipal Water District (NETMWD) contracts with the TCEQ to perform the Texas Clean Rivers Act of 1991 requirements to identify and prioritize water quality problems on behalf of the Cypress Creek Basin. The primary goal of this partnership is the establishment of a comprehensive water resources planning and management program that integrates water quality and water quantity issues within the basin.

The Clean Rivers Program water quality monitoring in the Cypress Creek Basin during the basin summary report period of 1998-2002 has taken place through a cooperative program directed by Northeast Texas Municipal Water District (NETMWD). Participants assisting NETMWD in planning, data collection, analysis, and reporting include Paul Price Associates, Inc. (PPAI), Texas Commission on Environmental Quality (TCEQ), the Clean Rivers Program Steering Committee members, basin partners Caddo Lake Institute (CLI) and affiliates, Pilgrims Pride Corporation, Franklin County Water District (FCWD), the City of Marshall, the City of Longview, Titus County Fresh Water District #1, Lone Star Steel, Texas Utilities (TXU), and AEP Swepco.

The goal of the Cypress Creek Basin Clean Rivers Program is to provide the appropriate, quality assured data to allow continuing assessment and management of water quality in the Cypress Creek Basin. Detailed objectives of this monitoring program include: · Establishment of a long-term monitoring program for the Basin, · Focus on and provision for local participation in monitoring, · Provision of reliable information to the public to enhance awareness and knowledge of water quality conditions in the Basin, · Monitoring and evaluation of water quality trends, · Identification of the nature and source of water quality problems that may result in significant impairments, · Evaluation of the applicability of Texas Surface Water Quality Standards to specific water bodies in the Basin, · Evaluation of permit requests with respect to water quality conditions and trends in the Basin, and, · Provision of data to support the development of cost-effective water quality management programs.

Identification of the nature and source of water quality problems along with evaluation based on the Texas Surface Water Quality Standards helps to assess permit requirements with respect to water quality conditions and trends in the Basin, and provides data to support the development of cost-effective water quality management programs.

A number of studies have been conducted in the Cypress Creek Basin in the last five years. The focus of these studies has been the improvement of water quality within the Basin, and documentation of watershed conditions both current and historical. Several of these studies have been produced within the Clean Rivers Program as special studies. Special studies are additional water monitoring projects designed to address a specific concern or to provide additional information as a result of a previous monitoring effort or a current issue affecting water quality. As part of the Texas Clean Rivers Program, these special studies deal with specific water quality issues or are used to support other programs (e.g., Total Maximum Daily Load development) addressing water quality issues in the Basin. Water quality and associated studies completed in the last five years include the following:

Hughes Springs Receiving Waters Assessment

TCEQ Region 5 staff performed the Hughes Springs Receiving Waters Assessment (RWA) in June 1998 to provide supporting aquatic life use information for the City of Hughes Springs wastewater permit renewal. This RWA showed that Hughes Creek, upstream from the discharge outfall, exhibited an “Intermediate” to “High” aquatic life-use rating when fish, macroinvertebrates, and habitat were evaluated.

Caddo Lake Organic Contaminant Study

This special study was designed as a preliminary survey of Caddo Lake to assess the presence of specific organic compounds in waters and sediment adjacent to the Longhorn Army Ammunition Plant (LHAAP). During the summer and fall of 1998, surface water and sediment samples were taken from Harrison Bayou and Goose Prairie Creek, which were waterbodies identified as being significantly contaminated with these compounds by the U.S. Corps of Engineers. The laboratory results for all samples collected during this Special Study were below detection limits. The report recommended further organic analysis studies surrounding the LHAAP. As a result, the TCEQ staff initiated an intensive study for ammonia perchlorate within Caddo Lake near the LHAAP.

Nutrient Study in Lake O’ the Pines

In anticipation of the data needs for TMDL (Total Maximum Daily Load) development, the CRP directed monitoring where possible, to address those needs. A nutrient study was developed to provide basic information about the Lake O’ the Pines, and its present nutrient load and trophic condition by identifying and quantifying the major nutrient storage pools (e.g., sediments, water, biomass), and plant biomass, distribution, taxonomy, photosynthesis and respiration in the water column. Additionally, bathymetric mapping of the lake, quarterly vegetation mapping, diurnal dissolved oxygen/temperature profiles, primary productivity studies and sediment nutrient parameter analyses were conducted. The data obtained during this study were used as part of the TMDL Development Workplan for the Lake O’ the Pines.

Poultry Operations Water Quality Impact Study. Appendix C of Poultry Operations Study, Report to the 76th session of the Texas Legislature.

This study examined existing or potential adverse impacts on water quality and biological communities in the Cypress Creek Basin as a result of concentrated poultry production and litter disposal activities. This involved the selection and sampling of four sub-watersheds in the basin, development of a Geographic Information Systems (GIS) database involving physiographic, vegetational, and landuse characteristics, and presentation of results and analysis of the resulting water quality data. The study documented the distribution of poultry production facilities and the magnitude of soiled litter disposal activity in the four study watersheds. Comparative monitoring results indicated that while indicators of intensive agricultural activity (nutrient and chlorophyll a concentrations, depressed dissolved oxygen concentrations) were generally present in Lilly and Prairie Creeks, whiuch drained the more intensively developed of the study watersheds.

Special Study of Poultry Operations

This special study, funded by Pilgrim’s Pride Corporation, was an extension of the previously mentioned special study mandated by the 76th Session of the Texas Legislature and was conducted under the directive of the TCEQ Clean Rivers Program with the objective to identify any water quality impacts specific to poultry production operations in the Cypress Creek Basin. The four sub-watersheds investigated during the original TCEQ study and a fifth sub-watershed downstream of the Pilgrim’s Pride Corporation Walker Creek Poultry Processing Facility were selected for monthly field parameter measurements and conventional water quality data collection. Habitat and biological assessments were conducted once during 2000 and 2001. Examination of poultry production and land disposal of litter for the two study periods was compared. The laboratory results showed little evidence of change in water quality parameters. No trends over time were evident in any of the data assessed, and nutrient parameters and dissolved oxygen levels exhibited similar patterns among stations during both periods. The Aquatic Life Use (ALU) scores based on the fish and benthic macroinvertebrate community assemblage at all five special study streams showed no dramatic change from the values observed from the 1997-1998 study and remain in the range between Intermediate and High integrity classes. The fecal coliform minimum and maximum concentrations were lower during 2000-2001 sample period than during the initial study possibly due to the relatively lower stream flow regime rather than the general decrease in land disposal of chicken litter.

Tankersley Creek Indicator Bacteria Special Study, Upper Big Cypress Creek Watershed

Tankersley Creek was placed on the TCEQ’s 2000 303(d) list for exceeding bacteria levels established for safe contact recreation and remained on the 2002 303(d) list due to insufficient bacteriological data. A 12-month special study of the bacteriological water quality on the upper Big Cypress Creek including Tankersley Creek was conducted during FY2003 to determine if the impairment was warranted. The study was initiated and monitored under dry and wet weather conditions with the goal of obtaining a broader assessment of the bacterial water quality conditions in the two primary streams draining the Mount Pleasant, Texas area and of the reach of Big Cypress Creek receiving that drainage. The results of this special study supported the 2002 303(d) listing of Tankersley Creek in terms of distribution but did not determine the possible sources. Therefore, a new special study is being developed to further characterize the bacteriological water quality in relation to land use type in the upper reaches of Tankersley Creek.

Lake O’ the Pines Watershed TMDL Project

Lake O’ the Pines was determined to have impaired water quality, consequently a TMDL (Total Maximum Daily Load) project was instituted. This monitoring was administered through the TCEQ and its TMDL program. The TMDL monitoring program consisted of base flow and wet weather stream flow monitoring within the Lake O' the Pines Watershed. Automated battery- operated sampling systems supported stream flow and wet weather monitoring by collecting detailed information on rainfall-runoff relationships and allowing simultaneous sampling of storm runoff across the watershed. All of the TMDL field sampling and the final TMDL report have been completed at this time. Analysis of monitoring data and operation of models of the hydraulic and kinetic behavior of the watershed-stream network-reservoir system indicated that Lake O’ the Pines is being adversely by phosphorus loading. A reduction in the 2000 total phosphorus load to Lake O’ the Pines of 58% was estimated to be needed to allow Segment 0404 to meet its dissolved oxygen standard at all fixed stations.

OTHER WATER QUALITY-RELATED PROJECTS

Strube Egg Farm Water Quality Study, Camp and Upshur Counties, Texas

Water quality and biological communities were sampled over a period of one year to evaluate conditions during a seasonal cycle for comparison with data collected by the TCEQ regional office and the Clean Rivers Program (CRP) in the Cypress Creek Basin. The objective of the study was to document the water quality and aquatic life use integrity of an unnamed tributary of South Lilly Creek that receives surface runoff from a large egg production facility. This effort included physical-chemical measurements, assessment of fish and aquatic macroinvertebrates and chemical analyses of water and sediment. This report concluded that the egg production facility was affecting the water quality in the lower portion of the stream with respect to levels of the macro-nutrients, nitrogen and phosphorus.

Water Quality of Lake Bob Sandlin, Titus County, Texas

This report was prepared for the Titus County Fresh Water Supply District No. 1 to summarize the data collected from Lake Bob Sandlin, evaluate potential trends in water chemistry parameters, and characterize the present quality of the water in the reservoir. Water quality sampling and analysis using comparable, quality assured methods were collected at five stations in the main body of Lake Bob Sandlin and on two tributary streams. Because the direct comparison among these stations was compromised by the differing periods of record available, the data were presented by the average and range values of parameters collected from Lake Bob Sandlin open water stations at the same times. With few exceptions, parameter values at all stations tended to vary together, with greater differences evident between sampling periods than among stations within those sampling periods. Various individual parameters in the tributary streams differed from the values measured in the reservoir. Water quality in Lake Bob Sandlin closely resembles that in Lake Cypress Springs, which contributes the largest proportion of the water entering this reservoir.

Water Quality of Lake Cypress Springs, Franklin County, Texas

The Franklin County Water District (FCWD) has conducted water quality monitoring in accordance with the TCEQ Clean Rivers Program (CRP) since April 2000. Available historical water quality data were compiled and examined to summarize all collected lake data, evaluate potential trends in water chemistry parameters, and characterize the present water quality of Lake Cypress Springs. Information was accumulated from various deep and shallow lake water habitats monitored by TCEQ Region staff and FCWD and two tributary streams providing instream flow to the lake sampled quarterly in FY2002 as part of the CRP Systematic Monitoring Program. Statistical analyses of the 24-hr dissolved oxygen measurements, nutrients, and major dissolved constituents were used for data comparison among stations. It was concluded that major water quality problems are not presently evident in the open waters of Lake Cypress Springs. The near shore areas showed substantial evidence of enrichment, particularly when tributary inflow is present. This is possibly due to the development of rooted aquatic vegetation in shallow water areas that may restrict water circulation and recirculate nutrients through their growth and decay. Recommendations based upon the report findings were included for future consideration that may require the potential alteration of the current monitoring activities and possible additional data collection.

Geographic Information Systems

Assessments of the water quality concerns within the Cypress Creek Basin have been greatly assisted by the introduction of the use of Geographic Information Systems (GIS). This layer- based program allows for combining information from both geographic (map) and database (table) formats which are then utilized within the watershed inventory to locate and track information about monitoring stations, permitted discharges, agricultural operations, and other concerns within the watersheds.

The positions of possible areas of concern are determined utilizing a Global Positioning System (GPS), which produce latitude and longitude coordinates and whose information is then incorporated into the GIS program. Additional information relating to these positions such as sampling data or discharge information is linked directly to the mapped information. The relationships of the different layers that are mapped and spatially analyzed help to establish potential interrelationships and possible influence on water quality within the watershed. An example of this use could be the relative proximity of point or non-point source contributors to areas with identified water quality concerns.

Public Outreach

The Cypress Creek Basin outreach and public participation efforts have been greatly expanded during the last five years. In the summer of 1998 the Cypress Creek Basin webpage www.NETMWD.com was created on the Internet. Since that time, we have used this valuable resource to provide to the public a large range of information and data concerning our Basin. Initially, the newly created webpage focused on introducing the public to the functions of the Northeast Texas Municipal Water District and describing the Clean Rivers Program and how it operates within the Basin. Webpage emphasis has now shifted to providing stakeholders with steering committee meeting agendas and minutes, and to publishing water quality documents and current datasets that have greatly expanded our Public Outreach efforts.

A focus in the Cypress Creek Basin Public Outreach efforts is the encouragement of public involvement concerning the Clean Rivers Program and other basin activities. This involvement is an important part of the development of support for the program, and a means of obtaining broad-based recommendations from the public. The public can get involved in basin activities either through the steering committee meetings or volunteer activities. In addition, NETMWD has expanded the number of public presentations and events involving the distribution of information about the Clean Rivers Program and water quality within the Basin.

Significant Findings

Low dissolved oxygen concentrations occur in stream and marginal reservoir habitats throughout the Cypress Creek Basin. All the segments, except 0405 and 0408 (Lake Cypress Springs and Lake Bob Sandlin), have reaches on the Draft 2004 303(d) list, or for which concerns with low dissolved oxygen concentrations are expressed in the Draft 2004 Texas Water Quality Inventory. In most locations, the low dissolved oxygen concentrations are associated with low flow conditions and with high levels of photosynthesis and respiration. This does not appear to be the case in Little Cypress Creek (Segment 0409), or in marginal and backwater habitats in Caddo Lake, which exhibit only very limited changes in dissolved oxygen concentrations over 24-hour monitoring periods.

Except for ammonia, nutrient concentrations in streams rarely exceed TCEQ screening levels. However, total phosphorus and total nitrogen concentrations in streams throughout the Cypress Creek Basin are usually at levels that can result in excessive algal growth under low flow conditions, or in impoundments. The heaviest loads have been observed originating from the Tankersley Creek watershed, and to a lesser extent, from other tributary watersheds in the upper part of the basin, for example, Prairie and Lilly Creeks, and the tributaries to Lake Cypress Springs and Lake Bob Sandlin. The Southwest wastewater treatment plant in Mount Pleasant, which processes wastewater from the Pilgrim’s Pride Corporation poultry processing facility is the source of a large proportion of the nitrogen and phosphorus load in Segment 0404 of Big Cypress Creek. Some phosphorus and a large proportion of the nitrogen load is lost during transport in Big Cypress Creek from the vicinity of Mount Pleasant and Pittsburg to the headwaters of Lake O’ the Pines, presumably through biological activity and trapping in the floodplain.

The upper reservoirs on Big Cypress Creek are continuing to assimilate the phosphorus loads entering them. The stations immediately downstream of Lake Bob Sandlin and Lake O’ the Pines exhibit much lower total phosphorus concentrations than the inflowing waters with comparable, or lower, flows. However, Lake O’ the Pines appears to be a net exporter of nitrogen with respect to inflowing and out flowing waters. Atmospheric deposition of nitrates may be significant, as may fixation of atmospheric nitrogen by blue-green, which are common members of the algal assemblage in Lake O’ the Pines. Although the total phosphorus load entering Caddo Lake from Big Cypress Creek appears to be only about half that entering Lake O’ the Pines, and the load from James Bayou is unlikely to be as much as that, the lack of water quality data from Twelve Mile Bayou precludes any firm conclusions concerning nutrient assimilation in that water body.

Marginal and backwater habitats in Caddo Lake, as in Lake O’ the Pines, occasionally exhibit dissolved oxygen concentrations below the segment standard for support of aquatic life. However, these episodes are not generally accompanied by large daily changes in dissolved oxygen concentrations, and often reflect relatively constant, low concentrations throughout a 24- hour sample period. This is consistent with a lower nutrient load entering Caddo Lake than is the case in Lake O’ the Pines, and which consequently does not support similarly intense algal production during summer conditions. It is more likely that in Caddo Lake we are observing an intense oxygen demand from the sediments during summer conditions, primarily from decomposition of rooted plant mass-produced with nutrients from the sediments.

Despite the widespread occurrence of low dissolved oxygen concentrations, elevated nutrient levels and other water quality problems, biological communities in streams throughout the Cypress Creek Basin continue to exhibit the abundance, trophic structure (i.e., the mixture of herbivores, detritivores and predators), and diversity appropriate to, or better than, that expected based on the quality of the habitat at those locations. To the extent that low dissolved oxygen concentrations are associated with low flow conditions, it is likely that aquatic communities in the Cypress Creek Basin are, to some extent, adapted to tolerate conditions that occur at least occasionally during summer conditions even in minimally disturbed streams.

Locally, low pH values, toxicity in water and sediments, and mercury in fish tissues appear to be phenomena associated with the lower portion of the Cypress Creek Basin. The lower basin coincides with a predominantly acid soils and forested watersheds that result in “soft” , acid waters of relatively low buffering capacity. Those conditions, coupled with the intense biological activity associated with a warm, shallow, eotrophic environment are thought to be conducive to the mobilization of heavy metals (e.g., mercury) into aquatic food chains

Recommendations 1) Focus 24-hour dissolved oxygen monitoring on locations with inadequate samples for analysis. 2) Utilize 24-hour dissolved oxygen monitoring to investigate the dynamics of daily dissolved oxygen changes to help define the causes of problems. 3) Investigate the apparent increase in ammonia concentrations in Frazier Creek, a minimally disturbed stream that is an ecoregion reference. 4) Given the characteristics of the lower watershed, assess the relative importance of rainfall pH versus groundwater inflows following percolation through forest soils. 5) Continue studies to determine the sources of indicator bacteria in the Cypress Creek Basin. 6) Review laboratory quantitation limits currently obtained. Where large proportions (e.g., >33%) of analyses are resulting in censored values, either use more sensitive techniques or drop the analyses and use the conserved resources elsewhere.
