The Rehabilitation Of The Tampa Bay Estuary, Florida, Usa, As An Example Of Successful Integrated Coastal Management, R. R. Lewis, P. A. Clark, W. K. Fehring, H. S. Greening, R. O. Johansson, R. T. Paul

Reports

The first suggestion that controls on eutrophication and dredging impacts were needed came in 1969. The federal Water Pollution Control Administration recommended a water quality management plan and waste abatement program to control odour and other pollution symptoms in Hillsborough Bay, and a master plan for dredging and filling the bay.

Recent Improvements Of Water Quality And Biological Indicators In Hillsborough Bay, A Highly Impacted Subdivision Of Tampa Bay, Florida, J.O. R. Johansson, R. R. Lewis Iii

Reports

Hillsborough Bay, the eastern uppermost section of the Tampa Bay system, is surrounded by a large metropolitan complex, supports extensive industrial activity, and serves as a major shipping port of fertilizer products. The Bay was determined to be highly eutrophic during the late 1960s. The City of Tampa's primary sewage treatment plant and runoff from fertilizer industry activities were considered as the major sources of excessive nutrient loading. Loadings form both these sources have been reduced during the last 10 years, which has probably been the leading cause of improved water quality parameters such as water clarity, dissolved oxygen, and …

Recent Areal Expansion Of Seagrass Meadows In Tampa Bay, Florida: Real Bay Improvement Or Drought-Induced?, R. R. Lewis Iii, K. D. Haddad, J.O. R. Johansson

Reports

Johansson and Lewis have documented improvements in water quality apparently associated with concurrent improvements to sewage treatment, particularly at the City of Tampa's Hookers Point Sewage Treatment Plant. These improvements are at least partially responsible for the significant decreases in chlorophyll a and increase in water clarity documented in Hillsborough Bay and Middle Tampa Bay.

Draft- Nitrogen Loading And Ambient Chlorophyll-A In Hillsborough Bay (Tampa Bay), Florida: An Eutrophication Management Strategy, J.O. R. Johansson

Reports

The present report examines the past and current relationship between nitrogen loadings and ambient chlorophyll-a eutrophic subdivision of Tampa Bay (Task 1). A management strategy for eutrophication abatement, involving the reduction of present nitrogen loadings to levels which will sustain the desirable chlorophyll-a concentration and support persistent seagrass growth in the near future, is also presented for Hillsborough Bay (Task 3). The urgent need for a comprehensive long-term water quality and loading source monitoring program, specifically for Hillsborough Bay, is also discussed (Task 4).

Recent Improvements Of Water Quality And Biological Indicators In Hillsborough Bay, The Northeastern Section Of Tampa Bay, Florida, J.O. R. Johansson

Reports

The City of Tampa was implicated as a major point source polluter of Hillsborough Bay based on its release since 1951 of primary treated wastewater effluent into the bay. To alleviate nutrient loads into Hillsborough Bay, the City of Tampa upgraded its Hooker's Point facility to advanced wastewater treatment (AWT) with a 60 MGD capacity. The transformation from primary treatment to advanced was successive.

Distribution Patterns And Accumulation Rates Of Fine-Grained Sediments In Upper Tampa Bay, Florida, Gregg R. Brooks

Reports

Tampa Bay, a drowned river valley, is the largest estuary on Florida's west coast.

Surface sediments consist of a mixture of carbonate and terrigenous clastic sands and muds.

The objectives of this study are to determine accumulation rates and processes controlling the distribution patterns of fine grain sediments.

Impact Of Dredging In Tampa Bay 1976, Roy R. Lewis Iii

Reports

During the last 100 years four major types of dredging have impacted the bay: channel deepening, maintenance dredging, shell dredging, and dredging for landfill construction. These landfills have resulted in the loss of 44% of the original marine wetlands bordering Tampa Bay. Recent environmental concerns have halted landfill dredging and severely restricted maintenance dredging.
