2016 Hydrilla Treatment Updates
Overall, herbicide treatments will be scaled back in 2016 in the Cayuga Inlet. This will result in lowered Project costs and lowered herbicide input into local waters, while still maintaining management pressure on remaining hydrilla populations. Treatments in Fall Creek will be similar to those in 2015.
1. CAYUGA INLET: Primary treatment for 2016 will consist of Sonar treatments (low-dose, systemic herbicide. Active ingredient: fluridone). One (1) Sonar Genesis (liquid) injection unit will be installed at the NYSDEC fish ladder (southern inlet). Sonar H4C (pellet) treatment areas will also be covered under 2016 management strategies. Sonar H4C treatment areas will include: Cornell Boathouse bay, Cascadilla Creek, Linderman Creek, and East Branch of Cayuga Inlet. Once initiated, Sonar treatment will extend for approximately 60 – 90 days (depending on observed hydrilla growth/regrowth). NYSDEC permit approval for treatment will be completed on July 15, and treatment in Cayuga Inlet will start on Friday, July 22 In Cayuga Inlet.
NOTE: Since there will be no contact herbicide treatment (Aquathol-K) in Cayuga Inlet in 2016, there will be NO closure of the inlet for 24hrs. Again, Cayuga Inlet will NOT be closed for 24hrs in association with herbicide treatments in 2016. The Inlet will remain open for boating and recreational use!
2. FALL CREEK: Primary treatment for 2016 will involve Aquathol-K (contact herbicide. Active ingredient: endothall) injection treatment to the main channel of Fall Creek AND Aquathol-K spot-treatments in backwater areas (golf course lagoon, Fall Creek cove, Stewart Park pond, and DEC wetland). An injection unit will be installed upstream in Fall Creek (adjacent to Lake Street Bridge), which will meter in Aquathol-K product over a 24hr period. Herbicide applicators will use johnboat/backpack application equipment to treat the backwater areas of Fall Creek.
Follow-up Sonar H4C (low-dose, systemic herbicide pellets. Active ingredient: fluridone) will be applied to Fall Creek backwater areas for approx. 60 – 90 days (depending on observed hydrilla growth). Sonar H4C treatments will help address possible hydrilla regrowth following the initial Aquathol-K treatment.
The Hydrilla Task Force (HTF) is currently coordinating with Project contractors for installation of injection unit prior to treatment initiation. NYSDEC permit approval for treatment will be completed on July 15, and treatments in Fall Creek will likely occur in early August*
*Treatment initiation will depend upon observed hydrilla germination and growth AND weather/flow conditions
3. SOUTHERN CAYUGA LAKE: An isolated hydrilla patch was discovered in late 2015 (adjacent to Cornell Sailing Center, in 3 – 3.5 meters of water). The HTF plans to address this patch through physical removal and benthic barrier installation. Racine-Johnson Aquatic Ecologists (RJAE) has been contracted to conduct physical removal and benthic barrier installations in 2016. The HTF and RJAE are currently coordinating on ongoing plant community/hydrilla monitoring and sampling. Physical removal and benthic barrier installation timing will be based on growth observations conducted by RJAE. Additional physical removal and benthic barrier installation will be utilized (when/where applicable, based on any new hydrilla discoveries).
In conjunction with hydrilla treatments, the Hydrilla Task Force monitors herbicide concentration levels through extensive water quality monitoring and sampling. This helps to ensure public safety and the health of the aquatic plant community. Water quality monitoring results will be provided to the public through the Tompkins County Health Department website (http://www.tompkinscountyny.gov/health) and the official Hydrilla Project website (www.Stophydrilla.org).

2016 Hydrilla Treatment Updates:
Fall Creek:
To control the growth of the invasive aquatic plant Hydrilla (Hydrilla verticillata) in Fall Creek, the aquatic herbicides Aquathol-K (active ingredient: endothall) and Sonar H4C (pellets. Active ingredient: fluridone) will be applied. Application in Fall Creek will begin on Tuesday, August 9, 2016.
Aquathol-K application will be conducted via automatic injection unit to the main channel of Fall Creek (from Lake Street to the mouth of Fall Creek) over a 24-hour period and via boat/backpack application equipment in the backwater areas of Fall Creek (Stewart Park Pond and its feeder stream, golf course lagoon, Fall Creek cove, and the wetland area NW of the golf course lagoon).
The water use restrictions associated with use of Aquathol-K are:
· Swimming and bathing are prohibited in the treated areas for 24 hours after application according to Special Local Need Label # EPA SLN No. NY-080004.
· Animal and Livestock watering is prohibited for 14 days after application.
· Use of water for human consumption is prohibited when concentrations of the active ingredient (endothall) are greater than 50 ppb (parts per billion) in the treated water.
**There are no fishing restrictions while Aquathol-K in use**
**Be advised that consuming water directly from any lake or surface stream is never recommended**
Sonar H4C application will be conducted using pellet broadcasting equipment in the shallow backwater areas of Fall Creek (Stewart Park Pond and its feeder stream, golf course lagoon, Fall Creek cove, and the wetland area NW of the golf course lagoon). Once initiated, Sonar H4C treatments will continue for approximately 60-days (depending on observed hydrilla growth).
The water use restrictions associated with use of Sonar H4C are:
· Do not use Sonar H4C treated water for hydroponic farming until concentrations of the active ingredient (fluridone) are less than 1 ppb.
· Do not use Sonar H4C treated water for irrigating greenhouse or nursery plants until concentrations of the active ingredient (fluridone) are less than 1 ppb.
· Irrigation or spraying of established tree crops and established row crops, turf, or plants is prohibited for 7 days after application.
· Irrigation or spraying of newly seeded crops or seedbeds is prohibited until concentrations of the active ingredient (fluridone) are below 5 ppb.
**There are no swimming or fishing restrictions while Sonar Genesis and Sonar H4C are in use**
**Be advised that consuming water directly from any lake or surface stream is never recommended**
Cayuga Inlet:
Following initial Sonar H4C applications (conducted on July 22, 2016 in Cayuga Inlet and planned for August 9, 2016 in Fall Creek), additional “bump” treatments must be conducted to bring herbicide concentrations back up to effective target levels. The bump treatment process will continue every 2 – 3 weeks through the end of September/early October. A Sonar H4C bump treatment will be conducted in Cayuga Inlet on Tuesday, August 9, 2016. Please refer to Sonar H4C water uses restrictions (above).
In conjunction with hydrilla treatments, the Hydrilla Task Force monitors herbicide concentration levels through extensive water quality monitoring and sampling. This helps to ensure public safety and the health of the aquatic plant community. Water quality monitoring results will be provided to the public through the Tompkins County Health Department website (http://www.tompkinscountyny.gov/health) and the official Hydrilla Project website (www.Stophydrilla.org).
