leahwoolam's Identifications

Observed during a random shoreline search at Sunset Point on Lake LBJ (a private RV resort) west of Marble Falls (Lake LBJ), 1:15 – 2:30 PM, located in the Colorado River basin in Burnet County, Texas. Permission was obtained from the Sunset Point property management prior to beginning our survey. The lat/long was approximately 30.564, -98.342. We walked approximately 550 feet. The substrate was mostly sand with some gravel and a few cobbles. Water levels were down approximately four feet in Lake LBJ due to an intentional drawdown by the Lower Colorado River Authority (LCRA) for dock maintenance and cleanup after historic flooding in the fall of 2018. The weather was sunny, but cold and windy. 1 shell.

Taken on Lake Creek Trail in northwest Austin, Williamson county.

I was surprised to find so many dead and a few living freshwater mussels in the creek. All I inspected seemed to be the same species, but I have no experience identifying them. Hoping for some help from the iNaturalist community!
