Upper Hillsborough River Diagnostic Watershed Assessment Final Project Report, Limno-Tech, Inc. (Lti), Southwest Florida Water Management District (Swfwmd)

Reports

This report was prepared under a contract between Limno-Tech, Inc. (L TI) and the Southwest Florida Water Management District (SWFWMD) for a diagnostic assessment study of the Upper Hillsborough River watershed. The Hillsborough River drains more than 695 mi2 of predominantly agricultural lands in Pasco, Polk, and Hillsborough Counties. The present investigation focused on a 650 mi2 area encompassing the northern and central drainage segments of the Hillsborough River Watershed (Figure E-1). Of particular concern to this investigation is the Hillsborough River reservoir, which is designated as a Class I water based on its use as a potable water supply. …

Comparisons Of Gears And Vessels Used In The Virginia Institute Of Marine Science Juvenile Finfish Trawl Survey, David Hata

Reports

The Virginia Institute of Marine Science (VIMS) currently conducts a monthly trawl survey in the three major Virginia rivers and the lower Chesapeake Bay to estimate the abundance of economically important finfish species, particularly at the juvenile stage .. VIM:S has conducted similar trawl surveys in various forms since 1955. Although this represents a 40 year period, variations in sampling design and gear have confounded efforts to produce a meaningful, continuous time series. Such variations include changes in stations occupied, sampling frequency, _vessels, and trawl gears. Much of the trawl survey sampling has been documented (Wojcik and Van Engel 1988a, …

Results Of The City Of Tampa Surface Water Compliance Monitoring Program For The Year 1996 And Examination Of Long-Term Water Quality And Biological Indicator Trends In Hillsborough Bay, City Of Tampa Department Of Sanitary Sewers

Reports

This report is submitted to the Florida Department of Environmental Protection (FDEP) to satisfy the requirements set forth in specific condition No. 14 of the Howard F. Curren WWTP permit No. D029-184532B. The report is based on data obtained by the City of Tampa (COT) compliance water quality monitoring program approved under construction permit DC29-152799. The report also includes examination of long-term trends for water quality parameters and biological indicators collected by the City of Tampa Bay Study Group and the Environmental Protection Commission of Hillsborough County (EPC).

Seagrass And Caulerpa Monitoring In Hillsborough Bay Eighth Annual Report, City Of Tampa Department Of Sanitary Sewers

Reports

This is the eighth annual report to FDER to satisfy the requirements set forth in specific condition #14 of FDER construction permit DO29-1845321B.

The City of Tampa, Bay Study Group (BSG), has monitored the effects of sewage pollution abatement in Hillsborough Bay since 1976. Within the last decade, water quality improvements and evidence of minor seagrass revegetation in Hillsborough Bay prompted the BSG to initiate a seagrass study to compliment other programs assessing the environmental status of Hillsborough Bay.

Effects Of Seagrass Biology On Water Quality In Shallow Regions Of The Lower Chesapeake Bay : Final Report, Kenneth A. Moore

Reports

The changes in water quality within shallow water regions of the lower Chesapake Bay was compared seasonally from permanent stations located along transects across vegetated and unvegetated sites in shoal regions of the lower Chesapeake Bay. The effect of the seagrass bed on conditions inside compared to outside of the bed varied seasonally and could be related to bed biomass and develoment. During spring (April-June) the rapidly growing seagrass bed was a sink for nutrients, suspended inorganic particles and phytoplankton, while during the summer, as bed dieback progressed, resuspension and release of nutrients were observed. Reductions in suspended particle concentrations …

Body Burden Of Polycyclic Aromatic Hydrocarbons And Tributyltin In Hard Clams, Mercenaria Mercenaria From The Elizabeth River, Va, Morris H. Roberts, Michael A. Unger

Reports

The Elizabeth River, contaminated with PAH, TBT, and heavy metals, is potentially home to a variety of estuarine invertebrates of commercial importance, notably oysters, hard clams, and crabs. Harvestable oysters have virtually disappeared from the system, but it has been rumored among commercial fishermen that a population of small (little neck to cherrystone) hard clams (Mercenaria mercenaria) exists within the Elizabeth River system. These clams are of serious interest to commercial clammers in the area as a previously unharvested source of market-size clams. Crabs of a harvestable size are also reasonably abundant throughout this river according to local fishermen.

State Of Tampa Bay 1996, J.O.R. Johansson

Reports

The amount of phytoplankton present in Tampa Bay waters can be estimated from measurements of the green plant pigment chlorophyll-a. Phytoplankton is one of several major forms of plants that exist in Tampa Bay and most other estuaries. Other major plant types are submerged seagrass, macro-algae and benthic micro-algae. The different plants can be viewed as being in competition with each other for required resources, such as light and nutrients. Studies conducted in urbanized estuaries have shown that excessive loading of nitrogen generally is accompanied by an increase of phytoplankton and macro-algae, including epiphytic and drift macro-algae, and by a …

Distribution Of Submerged Aquatic Vegetation In The Chesapeake Bay And Tributaries And The Coastal Bays - 1996, Robert J. Orth, Judith F. Nowak, David J. Wilcox, Jennifer R. Whiting, Leah S. Nagy

Reports

SA V distribution data in this report are presented and discussed based on the segmentation scheme adopted by the Chesapeake Bay Program (Flemer et al., 1983) and described briefly in the Methods section of this report. This zonation scheme (Upper, Middle, and Lower zones) for Chesapeake Bay, which accommodates the Chesapeake Bay Program segmentation boundaries, was adapted from that used in previous SAV distribution reports (i.e., Orth et al., 1994) and established by Orth and Moore ( 1982), then modified by Orth et al., ( 1989). The 1996 data were edgematched using ARC/INFO GIS software, as were all the historical …

Virginia Game Fish Tagging Program Annual Report 1996, Cm Bain Iii, John A. Lucy

Reports

The Virginia Game Fish Tagging Program (VGFfP), a cooperative project of the Virginia Marine Resources Commission and the Virginia Institute of Marine Science (VIMS), enjoyed its second full year of operation in 1996. Participation in the project, which is funded with revenues generated by Virginia's saltwater recreational fishing license, nearly doubled with 127 anglers volunteering as taggers compared to 64 in 1995.
