FINAL SOO will be submitted at time of Request for Proposals Project Title: Understanding Thermal Mixing, Water Quality, and Algae Dynamics with the Pulsing of Releases from Jordan Reservoir in the Cape Fear River. Responses to this Request for Statements of Interest (RSOI) will be used to identify potential investigators for a project to be funded by the US Army Corps of Engineers (Wilmington District)-Sustainable Rivers Program. The work involves comprehensive support of researchers in studying pulses and flow prescriptions to aid in basin wide efforts, and USACE relationships with water users as well as examining the effectiveness of water releases to achieve the desired outcomes while all in accordance with 10 U.S.C. § 2358 - Research and Development. Approximately $40,000.00 is expected to be available to support this project, for the base period. Additional funding may be available for follow on work in subsequent fiscal years to the successful recipient/awardee. Background: The Cape Fear River Basin was added to a nationwide program called The Sustainable Rivers Program (SRP) in 2016. The mission of SRP is to improve the health and life of rivers by changing water infrastructure operations to restore and protect ecosystems, while maintaining or enhancing other project benefits. The SRP attempts to analyze the effects from dams and use reservoir operations to enhance and manage downstream (and sometimes in lake) ecosystems. The Cape Fear River Basin was chosen for the SRP because of its complex human-ecology relationships, the expert stakeholders in the basin, and because the Corps-owned B. Everett Jordan Dam (Jordan Dam) has potential to influence fish and wildlife habitat, water quality, and other natural resources. The Cape Fear River Basin contains over two million people (2010 census), one-fifth of the state’s population. This includes growing urban areas of Durham, Greensboro, Pittsboro, Fayetteville, Wilmington and other cities, which contribute urban runoff into the river, but many of which also get a portion of their drinking water from this waterbody. The basin also supports 95 species of recreational fish, 42 rare aquatic species, as well as streamside habitat containing some of the oldest trees east of the Rocky Mountains; some of which are over 2000 years old (Stahle, 2012). Natural and human environments rely on the Cape Fear River, making its water quality and water quantity of the utmost importance. There have been multiple harmful algal bloom outbreaks behind Lock and Dam 1. These algal blooms are harmful to the health of the aquatic ecosystem, resulting, at times, in fish kills. The Cape Fear River also has many drinking water users, especially near locations of historic algal blooms. The algal blooms impact the treatment capacity of the many water supply systems on the Cape Fear River. Note: Must be a non-federal partner in the Piedmont - South Atlantic Coast, Chesapeake Watershed, or Southern Appalachian Mountains CESU Unit Region. Brief Description of Anticipated Work (Please refer to Statement of Objectives for complete detailed objectives and tasks): This project focuses on the following objectives: I. Understand thermal stratification of the Cape Fear River, especially near Lock and Dam 1, and ideally another location between Jordan Dam and Lock and Dam 3; II. Correlate different flow rates with potential thermal mixing of the water column; III. Track water quality constituents, especially chlorophyll a, as it relates to flow; IV. Relate the Corps’ water management to water quality and investigate the influence of releases out of Jordan Reservoir. Period of Performance: The base period of performance is anticipated to be twelve (12) months from date of award. Four option periods, extending for 12 months each, are anticipated subject to availability of funds. Note: A full study proposal and proposed budget are NOT requested at this time.
