Dear Sir or Madam:

I am pleased to discuss the status of the work I am currently doing at the Blackburn Fork.  The creek is beautiful and full of aquatic life.  Everything is going as scheduled and the results will meet the deadline.

The attached progress report should make you more aware of the progress of the project.  I look forward to presenting my findings when the project is finished.

 

Sincerely,

Michael Railling

Environmental consultant

Project Summary

Problem: Are the aquatic invertebrates the same in pool and riffle habitats.

Objective: Show that the two habitats should be comparably different by scoring the different taxa.  Taxa Richness and Percent EPT’s will be measured

Expected Results:  In the pool, more tolerant taxa will be found.  The Riffle will support taxa that are more susceptible to poor water quality.

 

Work Accomplished to Date:  Sampling is completed.  All of the invertebtates found have been identified to genus and counted.  Taxa richness, percent EPT’s, and percent Chironomidae have been calculated.  All of the necessary literature has incorporated into the experiment.

Anticipated Work for Next Reporting Period:  The manuscript will be finished.  A power point and poster presentation will be prepared with all the necessary tables and figures.

 

Problems Encountered:  The only Problem than occurred was the loss of one of the samplers.  All the necessary adjustments have been made and it will not effect the data.

 

Appraisal:  All work to date has been successful.  There is a definite distinction between pools and riffles.

 

Recommendations:  Studies need to be continued annually to adequately acess the two habitats.
