For the past two weeks we have been presenting what our "job" was. What thats means is at the beginning of the year we were split up into groups. All of our jobs were something we gould test in Chimacum creek. There was nitrates, ammonia, P.H. (posotive hydrogen) flow rate, D.O. (which is disolved oxygen) and tempeature. In our classroom we have been presentating to the class what our job is and what it means. I learned soooo much!
Over all I think chimacum creek did fantastic. Now heres my proof. With the bugs in our creek we got 21 points. Now that could be better but overall that isnt that bad of a score.
Our average for water temperature was 33.5 degrees f. That is a pretty good average for Chimacum creek. At this temperature the salmon and other life is comfortable and algae wont over grow. Temperature is very important because without a temperature range eventually everything would die.
The average for P.H. (posotive hydrogen) was 6.3. This average for the creek is pretty good. P.H. is a balance of positive hydrogen ions and negative hydroxide ions. It tells how actitic the water is. Fish need a balance of alkaline and acid.
D.O. is dissolved oxygen. Our average is 9.16mg/L. This average is fantastic for our creek. It is very comfortable for the fish. Without dissolved oxygen the fish wouldnt live. Dissolved oxygen is the only soure of oxygen they have.
For ammonia the average was 2.828 mg/L. Now if that was true that would be very bad. But we believe that we had a probe that did not work. So we dont know what the average was but we know it for sure wasnt 2.828mg/L. Ammonia is a chemical that is used in cleaning agents. it is colorless and will kill the fish. The average for nitrates was 0.3. That is really good!
Nitrates is in fertilizers. Our average was 0.38mg/L. For our creek 0.38mg/L is very good. This means that the farmers this year did an outstanding job!
Our average for flow rate was 1.3459 cubic meters per secnd. This is very good for the salmon. Flow rate is the amount and speed of the water that passes by per second.
Overall Chimacum creek is pretty healthy. Everything was about where it should be.
RECCOMENDATIONS TO KEEP THE REEK CLEAN: 1. Dont litter. 2. Keep your gutters and drains clean because when garbage and other stuff goes down gutters and drains it ends up in lakes and rivers and oceans. 3.Keep fertalizers and other products away from the creek.
