| 摘要： | The Regional Waterway Management System for Manatee County is a collaborative effort by the Manatee County Community Services Department, the West Coast Inland Navigation District, and the University of Florida Sea Grant College Program. This report addresses, the tidal Braden River, extending from State Road 64 to the Ward Lake Dam; the Manatee River, from the I-75 bridge to the Lake Manatee Dam; and Bishop Harbor. A principal waterway management issue of the region is balancing the growth of its boating population with conservation and management of its estuarine and riverine resources. The project devises and uses methods that allow for the simultaneous use and protection of coastal waters, while still maintaining the economic vitality of coastal communities. This approach evaluates the human ecosystem (boat user) and waterway system (environment) jointly, concurrently, and spatially; and is consistent with municipal, county, Florida Department of Environmental Protection (FDEP), and WCIND goals of facilitating safe boating and reducing boating impacts on natural resources. The project's design criteria are: (a) fit channel maintenance to boat draft needs; (b) minimize impacts on bay habitats; (c) prioritize and evaluate management alternatives on a regional scale; and (d) identify information products, for boaters and shore residents, which encourage environmental awareness by users of neighborhood waterways and boat access channels. Information for the project area is presented in tables and maps for approximately 30 miles of navigable waterways, 543 boats, 941 moorings, 354 shore facilities, and 239 boating-related signs. The report is based on regional (1:24,000) and large-scale (1:2400) mapping of water depth, boat and facility characteristics, signage, and habitat (sea grass, mangrove). The waterway management needs of the area are uniquely defined by the geography of boat source areas (trafficsheds); there are waterways with many boats, and areas with few boats. The relations of (1) concentrations of boats to access channel length and (2) boat draft to controlling channel depth determine the degree of boat accessibility and channel restrictions. An understanding of these relations is fundamental to developing and implementing rational waterway management policy. |
