Course Objectives were for participants to gain an understanding of key concepts related to man-made recreational whitewater, have familiarity with common safety problems, exposure to design criteria, understanding of project development process, common project challenges, and required facility maintenance. The whitewater project process will be broken down into phases with key milestones and challenges identified in each phase. Participants learned the fundamentals of developing a project management plan for whitewater projects and provide basic information needed to successfully manage existing and proposed whitewater projects.

Classroom Component: (Time Required = 2-3 hours)
• River safety – Common problems
• Current recreational whitewater criteria – CWCB and Urban Drainage and Flood Control District
• Evaluating existing facilities
• Developing new whitewater
o Stakeholder involvement
o Permitting
o Fish passage
o Design
o Construction
o Startup
• Operations and Maintenance

Field Component: (Time Required = 2-3 hours)
• Visit several manmade whitewater sites on the South Platte River in Denver
• Objective: Provide real-world applications of classroom material by field inspection of built manmade whitewater projects.

Course Outcomes:
• Understanding of key manmade whitewater concepts
• Familiarity with development of a whitewater project including key phases
• Ability to develop a project management plan
• Understanding of common mistakes and lessons learned
• Ability to effectively manage or participate in a manmade whitewater project

"Most of that money was to go toward tweaking. Now, we have major bank stabilization issues that aren't normal."
