Freshwater Mussel Surveys & Relocations

From Riffles to Rivers

Our team conducts surveys on waterbodies ranging from headwater streams to large navigable rivers throughout the southeast, northeast, and midwest. We have experience with low visibility diving, threatened and endangered species, and relocations. Mussel survey efforts have included presence/absence, reconnaissance, water withdrawal monitoring, and phase I and and II surveys, relocations, and mitigation efforts.


AllStar is also experienced in compiling and submitting all necessary data and reports to clients and agencies in a timely manner. Our staff members have extensive experience working alongside and directly with state and federal agencies to complete freshwater mussel surveys, as well as to expedite the reporting and project permitting process.

Big River Diving

Safety for AllStar’s staff and the environment as well as efficiency in project completion are our top priorities. AIIStar’s dive team follows the American Academy of Underwater Science’s Standards for Scientific Diving. All of our divers are PADI Advanced Open Water Certified and our Lead Divers are PADI Master Divers. Our survey team is fully equipped with boats, underwater communication units, photo and video cameras, and all appropriate safety gear. We have conducted surveys in the Ohio, Kanawha, Elk, Cumberland, and Allegheny Rivers often under low visibility conditions. AIIStar divers are certified in dry suit diving to allow for cold weather conditions or extensive water exposure.

Threatened & Endangered Species

Our survey team has significant experience surveying for Threatened & Endangered freshwater mussel species and we have experience handling and identifying threatened and endangered species in West Virginia, Ohio, and Pennsylvania. Our mussel team is also trained in Section 7 Consultation.

Mussel Survey Project

Pipeline Mussel Survey & Relocation

AllStar conducted a series of mussel surveys and subsequent relocations for a natural gas pipeline repair and low water crossing improvement project on Leading Creek in Gilmer County, WV. A diverse and dense mussel bed was observed using bathyscopes, snorkeling, and SCUBA equipment, resulting in the relocation of nearly 400 freshwater mussels with representatives from 13 different species.

Mussel Survey & Salvage for Dam Removal Project

AllStar Ecology partnered with the USFWS and WVDNR to survey for and relocate freshwater mussels in conjunction with the removal of three low-head dams on the West Fork River in Harrison County, WV. AllStar was responsible for coordination, survey design and implementation, mussel identification, and relocation efforts. Over 1,500 freshwater mussels were relocated through the cooperative efforts of state and federal agencies, private industry, and local volunteers.

Big River, Low Visibility Mussel Survey

In spring 2016, AllStar divers conducted low visibility mussel surveys in the Monongahela River in Monongalia County, WV. Highly trained surveyors conducted multiple dives from AllStar’s custom dive boat using dry suits and full face mask communications. Divers surveyed areas where bank stabilization would occur, outfalls would be placed, and relocation areas for salvaged mussels.
