Effects of Gas-Pipeline Construction on the Little Miami River Aquatic Ecosystem
A study was conducted to quantify the effects of a pipeline-construction project on the physical, chemical, and biological characteristics of the Little Miami River in Glen Helen Nature Preserve near Yellow Springs, Ohio. Suspended-solids concentrations, generally less than 25 mg/L for one month prior to construction, rose to a maximum of 1461 mg/L during construction (October 17-18, 1983). Suspended-solids concentrations then decreased to less than 50 mg/L within 12 h following trenching activities. Silt and fine sand were found on the streambed within 175 m downstream of the crossing site one month after construction. No detrimental alterations of water chemistry were observed as a result of pipeline construction. Postconstruction collections indicated that complete benthic recolonization of the affected areas occurred within two to seven months, while the silver shiner (the numerically predominant fish species) became reestablished in the affected stream reach within one month. However, densities and size distributions were decreased at and below the crossing. Collections taken within one year of construction revealed that fish-community characteristics were similar to those that existed prior to construction. Overall, impacts on benthos and fish associated with construction were minimal and short-term.
