A Survey of Freshwater Mussels (Family Unionidae) at Lake Nocona, Montague County, Texas

Authors: C.R. Randklev, B.J. Lundeen, J.H. Kennedy

This report documents the first phase of a long-term study to monitor the effects of draw-downs and long-lasting droughts on unionid populations in Lake Nocona, a West Texas impoundment. The aim of this survey is to provide a comprehensive baseline for future studies. While the Red River drainage in West Texas has been surveyed in previous studies, little is known about unionid fauna at Lake Nocona (Howells 1997). Lake Nocona is situated off FM 2634, 12.8 km northeast of the City of Nacona in Montague County, and was formed by impounding Farmer’s Creek in 1960. This lake serves as a source for drinking water and recreation (TPWD 2007).
