Creek Report
Name ______Blk______Date______NB#______
Scenario
Objective:
As we study Cane Creek, you will be making visual, chemical, biological, and physical observations. Research will be completed regarding the watershed’s natural and human interactions with the creek. The information you gather will then be generated into a report.
Scenario:
You have been asked to implement a scientific study of Cane Creek, you will be writing a report to a local North Carolina legislative delegate. This report was requested to determine if any further legislation is warranted for maintaining Cane Creek’s healthy role in the community.
Cross Curricular Guidelines:
Data Collection:
Several chemical tests will be conducted on the water: pH, nitrate levels, ammonia levels, and dissolved oxygen. Using a kick net, an attempt will be made to get a population estimate and identification of the aquatic insects found in the stream. Finally, we will be gathering general information regarding Cane Creek including, but not limited to: water temperature, stream depth, flow speed, vegetation, stream bed conditions, and water color & smell. These physical attributes will be logged on a Stream Survey form.
Community Awareness:
A map will be drawn of the Creek’s movement through the campus of Cane Creek Middle and how natural and human interactions impact its health. You will determine which watersheds this water continues to flow through, prior to reaching the ocean. You will research key legislative efforts made to safe guard waterways.
Statistical Analysis:
The data gathered will be plotted and analyzed. A spreadsheet will be prepared to generate the graphs, one of which will later be imported into your presentation. All computations will be maintained within the report folder for future verification. Students will be required to create a pictorial graph of the life forms found in each category, a concurrent graph of temperature, pH, and dissolved oxygen as the numbers change over the day. An analysis of these relationships will be examined.
Communication Skills:
Upon completion of the initial draft of the report, students will assemble in peer pairs to evaluate each other’s report to confirm information is presented in a clear manner, all information requested is present, and to verify the grammar is cohesive.

ONCE AGAIN DO NOT START OUT MAKING ANYTHING TOO BIG!!!! The school should be about center on the page and should not be much larger than quarter with the three halls coming off it like a spider. Don’t forget to have the creek traveling through your map!!! COLOR your map!!! Roads should be……Black. The school should be…..Red. The swimming pool should be……Blue. The sports fields should be……can you guess?
Points to Consider ON WATERSHED Walkabout
What attributes of a watershed impact the quality of the water? Think about the watershed as a large bowl made of sponge material. When it rains – the much of the water soaks into the ground and is used by the plants – however, if we wait water will slowly begin to move to the base of the bowl. In a watershed, like Cane Creek’s, the rainfall moves through the soil and eventually reaches the river. As it travels, much can be brought along with the water – chemicals, microorganisms, soil particles (erosion). This impacts the quality of the water in the creek.
We will be walking around the school today to consider potential hazards to the creek – not all hazards are presently having an effect on the creek. However, these hazards are, none the less, present and need to be monitored.
Station 1: End of 8th Grade Hall
Septic system for the school – waste matter from the school is sent to this building to be processed and then the water (and chemicals used to process it) travels through a pipe to the creek.
Cow pasture - cows have been known to trample fencing and get into the creek – farmers can get fined for such infractions because cows do not just go down to the creek to drink water….
Station 2: End of 7th Grade Hall
Up keep and maintenance of the Ball fields means grass clippings and sometimes fertilizers - Depending on the amount of any given rain fall, some of the clippings and fertilizer could be deposited into the creek
Station 3: End of the 6th Grade Hall
Note the housing development and the tomato farm, both of these locations can cause a change in water quality – either with erosion or the pesticides, herbicides and fertilizers used.
Station 4: Car Rider Circle
Once again the upkeep of the field (grass clippings and fertilizers) can impact the creek.
Also, draw attention to the tree line on the other side of football field – this is a feeder ditch that carries water and any other matter down to the creek.
Station 5: Corner near Softball Field
Have students look across the street and notice the community – some farm animals; however there are several house in that neighborhood. Each home has a septic field into which their waste goes - septic systems over time can leech (seep) pollutants which could run into the feeder ditch.
Station 6: Corner on driveway near pool
There is another feeder ditch on this side of the property.
Not if the pool had a chemical spill – much of this chemical would travel down the feeder ditch to the creek.
Station 7: Soccer Field Crosswalk
Looking at the parking lot – the vehicles leave pollutants that might wash towards the creek – but the grass acts like filter and helps keep much of this way.
Kitchen garbage area – the grease pit and the trash cans show leakage on the pavement– luckily there is enough grass presently to prevent this from reaching the creek
Station 8: End of 8th Grade Hall
Point out the roof of the building and have students ponder where the rain that hits the roof goes…
Return to class and have students begin making their maps – Please review the rubric.

TEST REVIEWS
Data Description and Note Page
Below are short descriptions of some of the tests we will be conducting on the Creek. These tests can help to paint an overall picture of the health of a body of water like our creek. Organisms do not like changes in their environment of any kind. Any changes add stress and the larger and faster the changes, the greater the stress.
What does it mean to say that a creek is healthy?
VISUAL WATER CHECK – Measured simply by making observations. Take a photograph to document general visual status of the area at the time of testing. As with most situations we tend to scan the area around us with our eyes. The information gathered from this visual observation can impact your initial attitude registered regarding the health of the stream - if litter and oddly colored water are seen or clear, bubbling water flow amid pruned banks is observed; assumptions will be different. Color may indicate inappropriate discharges, especially from industrial sources. A contaminated flow may also contain floatable solids or liquids. Pollution discharges often affect surrounding vegetation and their apparent condition can add information regarding the water quality.
Visual Water Check / Creek WaterSurface Status: / Creek Bed Description: / Litter Observed: / Other Notes:
⃝ Picture Taken
Write asentence about the visual aspects of Cane Creek and whetherthe creek appeared healthy or not.
WATER ODOR - Measured simply by making observations and using your sense of smell. Refer back to the Data Collection Chart of Observations on the section Odors from Creek Area. If the creek produces odors your nose can detect – this can be an indicator of pollutants that are impacting the health of the creek.
Transfer your data regarding the odors discovered at the creek:Manure / Rotten Eggs / Auto Fumes
Grass Clipping / Musky Smell / Fish Odor
Onions / Sour / Moldy
Other Odor Observations:
Write a sentence about the odors of Cane Creek and discuss whether your impression made you think the creek is healthy or not. Explain.
TEMPERATURE – Measured in degrees Celsius (°C) – temperature probe. Organisms prefer a specific range of temperatures. Too hot or too cold water can affect the health of a body of water. Temperature can affect many of the other tests done on water. As water temperature increases, dissolved oxygen levels decrease. Temperature levels can stress fish and other water organisms, making them more vulnerable to disease. Warm water temperatures above 35 degrees Celsius can result in enough stress to cause fish kills.
Temperature of water: Healthy Average UnhealthyDiscuss what attributes of the ecosystem could impact changes in temperature:
WIDTH & DEPTH
Stream width and depth affect many other characteristics of a stream. For example, a stream flowing through a wide, shallow channel will receive more sunlight throughout its water column. Increased sunlight will cause the shallow water to becomewarmerthroughout. Also, streams that have uniform depths across their entire widths tend to flow with greater velocity or speed because there is nothing to slow them.
Width (m): / Depth (cm):STREAM FLOW Measured in meters per second (m/s) – basketball, stopwatch, and measuring tape. Stream flow is a measure of how fast the water is flowing. Stream flow is affected by the depth, width, and the amount of rainfall a body of water has received recently.
/ Average Stream Flow:How does stream flow impact the types of biotic life and water quality? Explain.
COLIFORM BACTERIA - Measure as positive or Negative – Test Tabs. Fecal coliform bacteria are naturally presents in the human digestive tract but are rare or absent in unpolluted waters. Coliform bacteria should not be found in well water or other sources of drinking water. Their presence in water serves as a reliable indication of sewage or fecal contamination. This presence/absence total coliform test detects all Coliform bacteria strains and may indicate fecal contamination. If the test reveals that coliform is present, write at least 3 probable sources/locations around Cane Creek that this bacteria could be coming from. Then circle whether each location is point or nonpoint source pollution. Refer back to the walkabout if needed.
Positive Negative
- ______POINT or NONPOINT SOURCE
- ______POINT or NONPOINT SOURCE
- ______POINT or NONPOINT SOURCE
Animal Interaction
Organisms rely on water to live. Drinking, bathing and cooling down are primary functions that animals get from water use. Every water ecosystem supports a vast array of biotic organisms, the list is not limited to just aquatic plants and animals. How animals interact can affect the quality of the water – cows standing in the water or geese stopping for a time; each will have a very different effect on water quality.
Make a list of animals in the Cane Creek watershed. Discuss how they use the water source Cane Creek provides.Column Length

TURBIDITY – Measured in Column centimeters (Secchi disk) or NTU’s (Probe). Turbidity is a measure of how murky (unclear) the water is. The greater the turbidity, the harder it is to see through the water. Turbidity is caused by solid particles blocking sunlight from reaching the waterway’s bed.Turbidity is often measured using a Secchi disk. Turbidity affects organisms living in the water by clogging aquatic organisms gills, smothering eggs, absorbs more heat, ability to filter water for air, and fish cannot see prey.
Phosphate Reading: / Nitrate Reading:PHOSPHATES - Measured in a parts per million (ppm) – test tabs. Phosphate is a nutrient needed for plant and animal growth and is also a fundamental element in metabolic reactions. High Levels of this nutrient can lead to overgrowth of plants, increased bacterial activity, and decreased dissolved oxygen levels. Phosphates come from several sources including human and animal waste, industrial pollution and agricultural runoff.
NITRATE - Measured in a parts per million (ppm) – test tabs. Nitrate, NO3-N, measured in ppm, is also used to determine the "health" of the bacterial “scrubbers”. In an established waterway the flow of water is constant. Nitrate levels will normally stabilize in the 50-100 ppm range. Concentrations from zero to 200 ppm are acceptable. Nitrate is the end result of the nitrification cycle and is very important to plants in their life cycle. This is why the farmland can flourish from being irrigated with the water from the creek. The Nitrate concentration is controlled naturally through routine water change outs and to a lesser degree through plant/algae consumption.
Sources of Phosphates & Nitrates / Discuss how each source could impact Cane Creek:Cropland
Grazing land
Septic systems
Sewage treatment plants
Urban runoff
Average Conductivity
Write a sentence about the conductivity levels of Cane Creek and its health status:
CONDUCTIVITY – Measured in micro-siemensper centimeter (µs/cm) – Probe Conductivity is a measure of the ability of water to pass an electrical current. Conductivity is affected by the presence and amount of dissolved solids in water. The more dissolved solids (silt, plant matter, Ca, Mg, Al, Fe) the higher the conductivity levels. If conductivity levels are too high, especially due to dissolved salts, many forms of aquatic life are affected. The salts act to dehydrate the skin of animals. Conductivity values in lakes and streams are typically found to be in the range of 50-1500 µs/cm. Streams supporting a good mix of fisheries range between 50-500 µs/cm.
