Management Objectives:

Floating plants are managed at the lowest feasible level to conserve all of the uses and functions of this multiple use water body. Hydrilla in this lake is fluridone-tolerant. Hydrilla will be controlled in the western and northern areas of the lake to maintain flood control and public access and to enhance expansion of eelgrass. Hydrilla will be left in the southeastern areas of the lake to promote fishing. Hymenachne and Scleria will be controlled in a variety of wetland sites (to be determined throughout the year by FWC and SFWMD field staff) in order to limit the spread of this aggressive non-native species. Other plants are controlled to limit formation of monotypic stands to promote a more diverse native plant community and to limit formation of tussocks and floating islands. Management operations are coordinated among stakeholders and are conducted at the most appropriate times to increase cost-effectiveness and conserve the functions of the water body while minimizing disturbances to the users of this important resource. This workplan is a cooperative effort between SFWMD, the US Fish and Wildlife Service, and both the Aquatic Habitat Restoration and Enhancement (AHRE) and the Invasive Plant Management (IPM) Sections of FWC.

Major Water Uses:Flood protection, navigation, ecotourism, recreation, fishing, hunting

Species of Concern:

Snail Kite

Management Objectives:

Lake Hatchineha is south of Lake Cypress and north of Lake Kissimmee on the Kissimmee Chain of Lakes (KCOL) and is part of the greater KCOL watershed. The KCOL is one of the most important and diverse aquatic resources in the state. It is a designated Federal Navigation and Flood Control Project, providing a wide variety of uses and functions including: recreational fishing and hunting, endangered and listed species habitat, ecotourism and boating, and agricultural water supply. Floating plants (water hyacinth and water lettuce) are systematically controlled throughout the year to keep these invasive species at low levels to conserve all of the uses and functions of this multiple use water body. Hydrilla is established in the eastern lobe of the lake and is managed to maintain flood control and public navigation. Hydrilla is not established in the remainder of the lake and is managed to prevent establishment and to conserve existing native submersed plants, such as pondweed and eelgrass thereby promoting a more diverse native plant community. Water primrose (Ludwigia grandiflora/hexapetala) and burhead sedge/cuban bulrush (Cyperus blepharoleptos) are managed where found, in all areas of the lake, to prevent monotypic stands, tussock formation, reduce impacts to desirable native habitat and maintain access and navigation. Cattails are managed within the AHRES enhancement project area to facilitate the expansion of other native emergent and submersed aquatic vegetation. Management operations are coordinated among stakeholders and are conducted at the most appropriate times to increase cost-effectiveness and conserve the functions of the water body while minimizing disturbances to snail kites and the users of this important resource. This work plan is a cooperative effort between the South Florida Water Management District, the U.S. Fish and Wildlife Service, and both the Aquatic Habitat Restoration and Enhancement (AHRE) and the Invasive Plant Management (IPM) Sections of FWC.

Major Water Uses:Flood protection, navigation, ecotourism, recreation, fishing, hunting

Species of Concern:

Snail kite

Management Objectives:

Lake Kissimmee is the southernmost lake on the Kissimmee Chain of Lakes (KCOL) and is part of the greater KCOL watershed. The KCOL is one of the most important and diverse aquatic resources in the state. It is a designated Federal Navigation and Flood Control Project, providing a wide variety of uses and functions including: recreational fishing and hunting, endangered and listed species habitat, ecotourism and boating, and agricultural water supply. Floating plants (water hyacinth and water lettuce) are systematically controlled in all areas of the lake to keep these invasive species at low levels to conserve all of the uses and functions of this multiple use water body. Hydrilla is managed to maintain navigation, to promote the expansion of desirable native submersed vegetation, and at different levels in different areas of the lake for multiple uses/user groups. Each year, Invasive Plant Management staff meets with stakeholders through a series of public meetings to gather input that is incorporated into the hydrilla and other aquatic plant management plans. Annual treatment plans are crafted during late summer by the interagency advisory group and includes stakeholder input.

Water primrose (Ludwigia grandiflora/hexapetala) and burhead sedge/cuban bulrush (Cyperus blepharoleptos) are managed where found to prevent monotypic stands, tussock formation, and maintain access and navigation. Management operations are coordinated among stakeholders and are conducted at the most appropriate times to increase cost-effectiveness and conserve the uses and functions of the waterbody while minimizing disturbances to snail kites and the users of this important resource. This work plan is a cooperative effort between the South Florida Water Management District, the U.S. Fish and Wildlife Service, and both the Aquatic Habitat Restoration and Enhancement (AHRE) and the Invasive Plant Management (IPM) Sections of FWC.

Species of Concern:

Everglades snail kite

Management Objectives:

Floating plants are managed at the lowest feasible level to conserve all of the uses and functions of this multiple use water body. Hydrilla in this lake is fluridone-tolerant. Hydrilla will be controlled in the western and northern areas of the lake to maintain flood control and public access and to enhance expansion of eelgrass. Hydrilla will be left in the southeastern areas of the lake to promote fishing. Hymenachne and Scleria will be controlled in a variety of wetland sites (to be determined throughout the year by FWC and SFWMD field staff) in order to limit the spread of this aggressive non-native species. Other plants are controlled to limit formation of monotypic stands to promote a more diverse native plant community and to limit formation of tussocks and floating islands. Management operations are coordinated among stakeholders and are conducted at the most appropriate times to increase cost-effectiveness and conserve the functions of the water body while minimizing disturbances to the users of this important resource.
