<br /> <br />. <br /> <br />. <br /> <br />III-IS <br /> <br />Hydrological Design Objectives <br />Objectives have recently been adopted by Denver area governmental entities. <br />Objectives which relate to the boat chute planning and design are listed <br />below. <br /> <br />One-Hundred Year Design Flood. The lOO-year flood should be the basis <br />for design in the South Platte River corridor. <br /> <br />Erosion and Sedimentation. Bed and bank cutting by the river, and <br />related sediment deposition effects should be minimized. <br /> <br />Access Trail. Access to the river should be maintained for operational <br />and maintenance purposes, and to afford ready inspection of problem <br />areas. Such access trails serve for hiking and running, biking, and <br />non-motorized transportation. <br /> <br />Continuous Linear Boating. All dams and check dams should have navi- <br />gatible boat chutes suitable for the typical boater for river flows up <br />to 1,500 cfs. <br /> <br />Aquatic Life. Means to protect and enhance fishing and all forms of <br />aquatic life should be included in plans. <br /> <br />Birds and Terrestrial Wildlife. Enhancement of the riverine environ- <br />ment suitable for birds and terrestrial wildlife should be included in <br />the plans. <br /> <br />Drops and Check Dams. Design of river flow obstructions such as drops <br />and check dams must consider the impact of construction on the flood <br />carrying capacity of the channel. <br />
