Narrative for Piney Z
Piney Z Lake is named after the landmass around
the lake that resembles a Z. The lake has an area of 193 acres.
It also has 407 acres of surrounding property. Pine trees take
Karst topography is a landscape created by groundwater
dissolving sedimentary rock such as limestone. This creates land
forms such as shafts, tunnels, caves, and sinkholes. This is a picture of a experiment of putting phosphorous to help the lake. Apparently it didn’t work because the lake in the background wasn’t given the phosphorous and it looks very healthy. Floridian aquifer - In hydrology, a rock layer or
sequence that contains water and releases it in appreciable amounts.
The rocks contain water-filled pores that, when connected, allow
water to flow through their matrix. The floridian aquifer underlies
all of Florida, south Georgia, and parts of both Alabama and South
Carolina. Most of Florida’s drinking water comes from the
floridian aquifer. 3 billion gallons of fresh water are brought
up from this aquifer everyday. Piney Z lake has a sink hole that
goes into the Florida aquifer. This is a picture of the Florida aquifer Water Quality b) Dissolved oxygen – This is a measure of the amount of gaseous oxygen (O2) dissolved in an aqueous solution. Oxygen can get into the water by aeration, diffusion and as a waste of photosynthesis. Dissolved Oxygen is very important to Piney Z lake. It can affect the fish in a bad way if the dissolved oxygen level reaches above 110. Fish could develop gas bubble disease. This is where the bubbles block the flow of blood through blood vessels causing death. External bubbles can also occur and be seen on fins, skin and on other tissue. Oxygen is very important to all living things in Piney Z lake. Oxygen levels that remain below 1-2 mg/l for a few hours can result in large fish kills and this would not help the fishery at Piney Z at all. c) pH - pH is a measure of the acidic or basic nature of a solution. The concentration of the hydrogen ion [H+] activity in a solution determines the pH. Mathematically this is expressed as: pH = - log [H+]. PH is important to Piney Z lake because runoff from neighborhoods can change the pH and ultimately kill the fish. Different pH levels have different effects on underwater life.
d) Turbidity - Having sediment or foreign particles stirred up or suspended; muddy. Turbidity is important to Piney Z because living organisms in the lake cannot function well if the water is overly turbid and mucky. e) phosphates – these come from the element phosphorous. Organic phosphates are important in nature. Their occurrence may result from the breakdown of organic pesticides, which contain phosphates. They may exist in solution, as particles, loose fragments, or in the bodies of aquatic organisms. Phosphates stimulate the growth of plankton an of plankton and aquatic plants which in turn provides food for fish. This increase in growth could increase the fish population and improve the overall water quality. Too much growth could result in the death and decay of vegetation because of the decrease in dissolved oxygen levels. f) nitrates - Organic nitrogen is found in proteins and is continually recycled by plants and animals. Nitrates are important to Piney Z Lake because Nitrogen-containing compounds act as nutrients in streams and rivers. Nitrites can cause “brown blood disease” in fish. Poorly operated wastewater treatment plants, septic systems, and sewage leaks can add nitrogen to streams. We tested the dissolved oxygen by using a dissolved
oxygen kit. http://education.yahoo.com/search/be?p=pH http://www.state.ky.us/nrepc/water/wcpdo.htm dissolved oxygen http://www.state.ky.us/nrepc/water/wcpph.htm pH http://www.dictionary.com/search?q=turbidity |
