Three downstate ponds to be treated
for aquatic nuisance weeds
DOVER (May 29, 2014) – During the next three weeks, weather permitting, DNREC’s Division of Fish and Wildlife will be treating three downstate ponds for aquatic nuisance weeds that, left unchecked, can choke the waters, crowd out beneficial plant species, and prevent fishing and boating access. The three public-access ponds to be treated are: Millsboro Pond; Wagamons Pond near Milton; and Concord Pond near Seaford.
Hydrilla, a non-native plant that likely entered the state through the aquarium trade, is the primary target of the treatment. The Division’s Fisheries Section will apply Sonar, an EPA-registered and approved aquatic herbicide containing fluridone, to the ponds. In compliance with new guidelines issued by the EPA, DNREC has filed a notice of intent to use Sonar and has submitted a pesticide discharge management plan.
Sonar has been used in Delaware since the 1980s and proven safe and effective for controlling hydrilla. Sonar does not pose any threat to wildlife, including fish. “There are no restrictions on fishing or consumption of fish as a result of these planned treatments,” said Fisheries Administrator John Clark.
Signs will be posted in the boat ramp area of each pond on the day of treatment. The only special precaution for residents is a 30-day restriction from the day of treatment on the use of water from the ponds. “Residents who live beside the ponds and those directly downstream should not use pond water to irrigate their gardens, yards, or agricultural lands for 30 days following treatment to avoid possible damage to their plantings,” Clark said.
Clark also noted the Division of Fish and Wildlife would like to remind residents that in order to use water from Delaware’s freshwater ponds, an annual permit from DNREC’s Division of Water is required. Residents who have these permits will receive individual notice of the upcoming pond treatments.
To prevent the spread of invasive aquatic vegetation to other ponds and waterways, anglers and boaters are encouraged to remove all Hydrilla and other aquatic plants from their boats, trailers and gear before leaving the boat ramp area, Clark added.
The Division of Fish and Wildlife only treats state-managed ponds that allow public access, since this work is funded through the Federal Sport Fish Restoration Program and state fishing license funds. The Division does not treat private ponds, but can recommend businesses licensed in Delaware for treating them.
