Flatwoods Citrus Best Management Practice: Riser-Board Structures

Figure 2. Typical riser-board structure within a citrus grove drainage system. Water discharge structures are used to control water table levels and surface water levels in drainage and irrigation ditches within flatwoods citrus groves. The type of structure selected can significantly influence the quality of water discharged. With flashboard risers, water is forced to flow over the top board. This flow path creates a low current area toward the bottom, which facilitates the deposition of sediments and their accompanying nutrients or pesticides, essentially removing them from the discharges. Conversely, screw-gate structures do not create this dead-current zone. Since they open from the bottom, sediments are swept out along with the discharge water.

Flatwoods Citrus Best Management Practice: Soil Stabilization

This best management practice describes stabilization practices for erosion-prone soils within flatwoods citrus groves. Significant amounts of soil may be deposited in drainage ditches and canals because of the erosion of grove soils. These deposited soils reduce the capacity for holding and transporting water. Plus, very small soil fractions may be suspended in discharge water then settle out in slower flowing areas and destroy submerged aquatic habitats, resulting in the loss of fish, invertebrate, and plant species important for healthy ecosystems. Fortunately, a variety of slope stabilization methods are available. This publication describes considerations for using plants for stabilization, or mulch-like materials. Written by P.
