Black Hills streams have been a primary habitat for salmonid fishery, wild brown trout (Salmo trutta), rainbow trout (Oncorhynchus mykiss) and brook trout (Salvelinus fontinalis). Recently, a stretch of Rapid Creek, has experienced high water flow releases from Pactola Reservoir causing erosion and subsequent reduction in hiding spots/spawning areas for brown trout and other fish. An extensive habitat project has been carried out by the Game, Fish, and Parks involving placing boulders across the stream bed and burying wind-fallen trees along the bank to encourage the productivity of trout fisheries. A two-dimensional hydraulic model, River2D, will be used for hydraulic and habitat analysis. The modified post-construction stream habitat will be compared to pre-construction stream habitat using modeling and field observation to evaluate the effects on stream hydraulic parameters and stream habitat. The results from this research will be used to guide future habitat restoration by providing an accurate estimate of how stream morphology will impact existing habitats. The objectives for this project are; (1) Collect pre-and post-development stream cross-section data through surveying. (2) Create a pre-and post-development River2D model to analyze the effect of habitat restoration projects on hydraulic parameters. (3) Identify data that has been collected on depth, velocity, stream flows and fish distribution in space and time, and use this data to calibrate the models. (4) Assess the success of implemented habitat structures and their benefit to the streams habitat. (5) Use modeling results and field observation to guide future fish habitat restoration projects.

South Dakota School of Mines and Technology

Mackenzie Kenney was born on June 17, 1993 in Mitchell, South Dakota. She moved to Cincinnati, Ohio in the summer of 2002. On May 28, 2011 Miss Kenney graduated from Anderson High School in Cincinnati, Ohio. In August of 2011, Miss Kenney relocated to Rapid City, South Dakota where she began her undergraduate education at South Dakota School of Mines and Technology (SD Mines). On May 5th, 2016 Miss Kenney graduated with her Bachelor of Science with a degree in civil and environmental engineering, emphasis in environmental engineering, and minor in environmental engineering. During her undergrad, Miss Kenney was a four-year varsity letter winner for the women’s basketball team and was an active member of American Society of Professional Engineers (ASCE) both on and off campus. Miss Kenney continued her education and began her Master of Science at SD Mines in August of 2016 under the supervision of Dr. Stu Geza and Dr. Scott Kenner. Throughout her graduate studies, she worked as a research assistance on a project involving the available habitat for trout fishery in Rapid Creek for the South Dakota Game, Fish, and Parks (SDGFP). Also, during her graduate education, Miss Kenney joined the international organization of Graduate Women in Science (GWIS) and helped start the Black Hills Chapter. On May 5th, 2018, Miss Kenney received her Master of Science in in civil and environmental engineering with an emphasis in water resource engineering. Miss Kenney began her professional career upon graduation with US Army Corps of Engineering in Kansas City as a Hydraulics Engineer for their River Engineering and Restoration Department.
