  • Toccoa River Watch Thread!

    Water temp on the tailwater was 70 degrees at my place yesterday.
    I'm a couple of miles below dam... just above railroad trussel. This is not good!

    Thanks "Hydemaster" for the information.

    I spoke with someone at TVA about your findings. It was suggested in order for the information to be useful for TVA and Georgia DNR, they need what type of thermometer was used, where in the water column was it obtained, and where on the river (tailwater landmark) along with the temperature.

    You can shoot an email to this address blueridgerehab@tva.gov with your findings. I hope other interested people will do the same.

    Here is a link to the Blue Ridge Dam Rehabilitation website:

    It might not hurt to shoot Wayne Probst (Regional Fisheries Supervisor) an email too at wayne.probst@dnr.state.ga.us.

    You are right. This doesn't look good with an ongoing heat wave. As we prayed for rain, we might need to pray for cooler temps.

      Water temp at Horseshoe Bend

      On Friday and Sunday my readings were 64 degrees. I used a Fishpond thermometer for the readings.

        I am headed up to our cabin tomorrow to do some lawn work, and was curious if the releases are going non stop during the week. May take the rod if I can catch low tide...

          water temp

          I fished last Friday from Curtis Switch to McCaysville and the water temp was at 64 degrees at several different spots. Taken just below the surface.

            Update on the Toccoa River Drawdown

            After hearing of rising water temps on the tailwater, I contacted Georgia DNR (specifically John Damer). John responded to my concern with this reply:

            Becky, We are aware of the rising temps in the tailwater. We made our concerns known to TVA last week during Thursday's (8/5/10) DNR/TVA teleconference. TVA has been sending data to us on a weekly basis since the start of the drawdown, as per our agreement summarized in their final EA. Since the start of the drawdown, we have seen a fairly steady increase in water temperatures at a rate of close to 0.5*C per day. As of 8/5/10, we noted that if this trend of rising water temperatures continued at its current rate, we could see 20 degree water on or around August 10th, and 22 degree water by around the 15th. We sent our data to TVA and relayed our concerns to them about potential damage to the trout fishery in the Toccoa Tailwater. Based on the water temperature at the Low Level Outlet (already at 19*C on the 26th, releasing from here was not an option), the only option that was readily apparent to us (DNR) was to slow or halt the drawdown until cooler temperatures resume. We also relayed this suggestion to TVA. Thus far, TVA has not taken our suggestion to slow or halt the drawdown. TVA is scheduled to reduce the rate of draw from around one foot per day to around three feet per week, beginning this Friday (the 13th). We (DNR) do not have a hydrologist on staff, but we think there may be some chance of slightly cooler water releases when this happens, but we are not sure (has to do with the hydrodynamics around the intake, and how/where water is being drawn from). I'm sure that you and others will probably have more questions. Feel free to send them my way. John DamerFisheries Biologist, Region IGA DNR, Wildlife Resources DivisionP.O. Box 519Calhoun, GA 30703

            We are very fortunate to have John and GA DNR working diligently for the tailwater fishery.

            As of today, I noticed TVA has decreased the amount of generation during the day and looks to continue over the next three days. I don't know with the continued heat wave exactly what will occur, but, plan to reach out to GA DNR to keep us updated about findings.

              Toccoa River Watch Thread!

              Toccoa River Watch

              This thread is being created to serve as a place for all of us to track the developments on the Toccoa tailwater as they occur regarding the Lake Blue ridge draw-down and resulting threat to the Toccoa river fishery.

              This is not a place to vent about the drawdown, argue about river access rights, etc. The purpose of this thread is to allow us to exchange and relate current information so that we might stay informed on the realities of the situation and be better prepared to deal with and assist in helping to preserve this and similar fisheries in the future.

              Please post your streamside observations, temperature data, etc in this thread so that we can have a consolidated source of information to refer to. The health of one of one of Georgia's great tailwaters is at stake here and we need to stay informed and share information so that we can better influence and assist with decisions concerning this and future lake draw downs.

                  I did an Adopt-A-Steam analysis last Sunday (and plan to do so periodically during the dam repairs) just to have another set of eyes on river conditions independent from the TVA monitoring. The testing was done at my place on Hogback and everything looked in a good range for trout so far. Although the trend doesn't look favorable, let's hope for the best. The following is the data I recorded.

                    The draw was halted today from 7am until 3pm (per the TVA’s web site last night) I really do want to fish and even thought of taking a “sick day” but I do not know if the fish will do well after release (with the warm temps and all). Yea, I know, I gotta catch em first. A swag on my part of the variation in temps are due to the angle of the light/ penetration into the water, time of day ect. The mean is just too close to push it imho. Hay! I sound like a trout hugger!

                      Just got this report from Ralph Artigliere:

                      Report on the tailwater: It fished really well today. I got in about 11:30 am and it was 69 degrees using a mercury thermometer and when I got out at 2:15 it was 71 degrees just a few hundred yards downstream. The fish were very cooperative, and nearly 50% were the browns DNR stocked a couple months ago. They have not traveled very far, but they are spread out.

                      None were really big (except one rainbow that took me from one bank to the other into a snag and broke off my leader and flies). The fish all seemed healthy (even the horny head I caught) and surprisingly fat in many cases. Since all but one were not giants and the water was a bit off color, I was able to use 4x flouro and bring them in quick so all were spry when released.

                        Update on Tailwater temperatures

                        David got the temperature of the river and looked at water conditions today at three public access areas on the tailwater. Here are his findings:

                        Tammen Park: Temp 70 degrees F
                        Unable to see the bottom, water was not clear
                        A few fish rising

                        Curtis Switch: Temp 73 degrees F
                        Water was noted to be somewhat clearer
                        No fish activity noted

                        Horseshoe Bend Park: Temp 74 degrees F
                        Able to see rocks on the bottom
                        No fish activity noted

                          Trout or Marters

                          I just stopped by Horseshoe Bend around 4:30 today and talked to a father and daughter up from Florida visiting and they were at the park fishing from about lunch on. They caught no fish and reported seeing at least a half a dozen floating by belly-up including one "quite large" as the father explained.

                          After dinner I am going to get official end of the day temps from the same locations as Becky Hulsey posted earlier to see if the day time highs today took the water over the top of the threshold. I certainly hope not. Lets hope our baby's in the tail waters are tough trout. I am also going to talk with one of the landowners that feeds regularly and see what he has to say. I will report my findings later.

                            Post your reports on the tailwater

                            Thanks for your report Trout Addict.

                            I have heard reports of 6 dead fish at Horseshoe Bend Park yesterday and 1 dead 10 pound rainbow at the Tammen Park area on Saturday. These were reports given to me. I did not see them.

                            I look forward to hearing your findings.

                            Also, please forward any findings to GA DNR. They appreciate reports from anglers.
