JOB COMPLETION REPORT As required by FEDERAL AID IN FISHERIES RESTORATION ACT TEXAS Federal Aid Project Non F~3uRwl4 Region 5~B Fisheries Studies Job No" Owl Pollution Studies Project Leader: Joe E“ Toole J” R. Singleton Executive Director Texas Parks and Wildlife Department Austin, Texas Marion Poole Eugene A; Walker D~J Coordinator Director, Wildlife Services March 8, 1967 A RS'IW'EAE'W‘ On April 88: 1966 a reported fish kill on LeTorneau Club Lake was investigated. The lake was covered by flood waters of the Sabine River and no indication of pollution was found. Numerous investigations were made on the Sabine River in Harrison County this segment. Limited fish kills occurred at various locations on the river. Chemical water analyses did not indicate any abnormalities in water quality. Salinity is normally high in this area of the Sabine River due to brine from the East Texas oil fields and natural sources. Continued efforts should be made to encourage area industries to improve their effluents to protect the fishery of the Sabine River and various tributary streams. It is recom~ mended that this job be continued to investigate future pollution activities. SEGMENT COMPLETION REPORT State of “ Texas Name: Region SWB Fisheries Studies Project No. Fw5~RelA Title: Pollution Studies Job No. C~l (Cont.) Period Covered: _ February 13 1966 « January 31. 1967 OBJECTIVES; To determine the source and nature of natural or manwmade pollutants ’7 which effect fish populations in the waters of Region ewB. TECHNIQUES: When evidence of pollution was reported or found to be present, a search was made to find the source and nature of the pollution. Standard water analyses including pH, total alkalinity, chlorides and dissolved oxygen were run.- FINDINGS: LeTourneau Club Lake On April 8 . 1966 an investigation was made on LeTorneau Club Lake in Harrison County at the request of Mr. Bill Turner, Club Officer. Flood waters of the Sabine River had flooded the lake and covered much of the watershed. Local guards reported that an extensive fish kill had resulted three days prior to the investigation. It is probable that the flood waters from the Sabine River introduced a pellutant into the lake although no evidence of pollution was found. Following the flood period, the lake was stocked with additional game fish species. No further reports of fish kills have been received to date. Sabine River Numerous reports concerning fish kills on the Sabine River in Harrison COunty were investigated this segment. Fish populations in this area of the River are subjected to both natural and man~made pollutants from the East Texas oil fields as well as numerous industrial effluents flowing into the river. A limited sport and commercial fishery prevails. The most important phase of the commercial fishery on the Harrison County portion of the Sabine River is minnows. Numerous riffle areas provide good food production and protective cover is adequate. ugi Data compiled at the United States Geological Survey daily sampling station near Tatum indicate that periodic slugs of saltwater flow through this area. Average chlorides compiled during fish kill investigations is BOO p.p.m. which is considerably higher than other area lakes and streams although well below toxic levels for most aquatic life. It is possible that a concentrated slug of brine could cause a local fish kill im minimum stream flow conditions and disperse into subwlethal concentrations before being detected. The most extensive fish kills reported on the Sabine River occurred in July, 1966 near Rocky Ford, a favorite recreational access point in Harrison County. The first fish kill was reported to have occurred on or about the 4th of July. Numerous fish were observed floating. Water analyses failed to indicate any abnormalities in the water quality. On July 28. a second fish kill was reported in the same area from Rocky Ford to the mouth of Hatley Creek, approximately 1 mile upstream. Again fish were observed floating, primarily river carpsuckers (Carpiodes carpio) and various sunfish species (Lepomis sp.). Routine water analyses again failed to indicate pollution. Heavy phytoplankton blooms were noted during both July investigations in the Rocky Ford area. Significant cone centrationS' of phosphates from upstream municipal sewage effluent could have indirectly caused these fish kills providing excess fertilization. The heavy plankton bloom in low streamflow conditions could have caused oxygen depletion in this area of the river. Table 1 contains water analyses data for respective investigations. The last investigation made on the Sabine River was on November 18, 1966. A fish kill was reported to have occurred 4 days prior to this date in the vicinity of Stillwell“s Store on Highway 59 in Harrison County. Several small sunfish and minnows were observed floating against the banks. As contained in Table 1, analyses data indicated no abnormalities with the exception of the test made on Potter”s Creek at Highway 45 bridge. Effluent from Atlas Powder Company in Marshall flows through Potter”s Creek which empties into the Sabine River. There are many possible factors involved in the pollution of the Sabine River in the East Texas area. Usually a pollutant has dispersed or moved downstream before a report is received and can be investigated.
