Acknowledgements
We express our gratitude to the following for their invaluable contributions to the mussel survey. Tim Petitgout of Frentress Lake Marine Center provided funding for the survey and the use of a workboat for the dive team to work from. Bob Schanzle and Dan Sallee served as a professional dive team, as well as highly qualified mussel biologists. Jenna Skopek served as biological technician, assisting with mussel collection, identification and measurement. We appreciate the time that Jon Duyvejonck of the Rock Island, IL, Field Office of the U.S. Fish & Wildlife Service spent with us in the field during the survey. Bob Schanzle kindly provided several mussel specimens from his personal collection for photographing.

Disclaimer
Most of the photos on the following pages are of mussel specimens that were collected either alive or dead during our mussel survey. However, for several species, either the photos did not accurately display the characteristics of the species, or individuals of the species were not photographed. In those cases, the photographs are of specimens from the personal collection of Bob Schanzle. These include Ellipsaria lineolata, Fusconaia flava, Lampsilis teres, Quadrula metanevra, Quadrula nodulata, and the image of the lone specimen of Truncilla donaciformis. These specimens were also collected from the Mississippi River, with the exceptions of L. teres and T. donaciformis, which were collected from the Illinois and Mackinaw (Illinois) Rivers, respectively.

Introduction
This photo addendum is a supplement to the report entitled "2013 Mussel Community Survey in the Upper Mississippi River, Pool 12 (Frentress Lake Area)". The survey was conducted on September 3 and 4, 2013, in an area of side channels near Frentress Lake Marina, East Dubuque, IL. The survey was conducted for the purpose of providing the U.S. Fish & Wildlife Service, U.S. Army Corps of Engineers, and Illinois Department of Natural Resources with information on the nature of the mussel community to allow for a determination on a permit application to dredge and deepen the side channel area. This application was made by the Frentress Lake Marine Center of East Dubuque, IL. Readers are referred to the above report for maps, information on GPS locations of survey plots, and specific information on the findings of the survey.
Photographs of individuals of most of the collected species of Unionid mussels were taken in the field. Most of the photos were of live specimens, although a few were of shells from either freshly dead (i.e., within one year) or relict specimens. In those cases where a photograph was overlooked in the field, or the photograph did not clearly present the features of the species, photos were taken of specimens from the personal educational collection of Bob Schanzle.
Over 1,000 Unionid mussels were collected in the course of the two-day survey, representing 20 different species. Information on relative abundance and distribution of species is provided in the full report. Amblema plicata (threeridge) was by far the most abundant species in this survey, representing 62.4% of the live Unionid mussel fauna. It was followed in descending order of abundance by Obliquaria reflexa (threehorn wartyback – 15.3%), Fusconaia flava (Wabash pigtoe – 7.41%), Quadrula pustulosa (pimpleback – 4.61%), Lampsilis cardium (plain pocketbook- 3.01%), Obovaria olivaria (hickorynut – 2.51%), Quadrula quadrula (mapleleaf – 1.80%), and Pyganodon grandis (giant floater – 1.50%). These 8 species comprised 98.5% of the live Unionid mussel community. The remaining species of live unionids (9 species) each comprised less than 1.0% of the mussel community, with three species represented by only 1 individual in the collection (i.e., Potamilus ohiensis – pink papershell; Truncilla donaciformis – fawnsfoot; and Utterbackia imbecillis – paper pondshell).
No individuals, either live or dead, were collected of species that are listed as endangered by the U. S. Fish & Wildlife Service. One live Liguma recta (black sandshell), and the valves of two dead black sandshells were collected. Also, a recently dead (i.e., specimen with both valves intact) Ellipsaria lineolata (butterfly) was collected. These two species are listed as threatened by the Illlinois Department of Natural Resources.
