Aquatic insect survey  November 8th

Saturday, November 8th will be our last survey for this year.  We have been doing these surveys for two years now and they have give us a better understanding of the food source for our trout and the health of our Clinch river.  Insects like trout must have clean cold water, some more than others and it is the density of some of these insects that promote and maintain the clean water we see in the Clinch. We have learned that the aquatic insects we see will vary with the season, example the Mayfly nymph will be more prevalent in the Spring than in the Winter months and we see a higher number of a certain insect in different parts of the river. How is this helpful to the angler?  You could see greater success using a bead head pheasant tail nymph in the spring vs the winter. In the Spring the size of you fly selection will be larger than in the colder Fall and Winter months. As with other things in nature, aquatic insects are cyclical, think about the Sulphur hatch that we had this past Spring and Summer.  It was much greater this year than in years past, no additional mayfly larva were put in the river and no other major changes took place. Water flows will impact the aquatic insects if the water level is very low for an exited period of time, but not as much as you would think . Remember while the work on Hibbs Island was being done? We conducted a survey shortly after water had been restored and saw little impact. 

We normally meet in the parking lot at Miller Island. Times will vary due to the release schedule. I will be contacting TVA for information on a release time as we get closer to the event. Detail information will be posted on our Facebook page and in an email to our Members.
