Once inside the snail, it develops further into a cercariae. That miracedium has about 24 hours to find and attach to the proper snail host before it runs out of energy and dies. The eggs hatch within an hour in the water and liberate a miracedium. Parasite eggs are released from the birds in their feces. The schistosome that causes swimmers itch has two hosts that it cycles between, birds and snails. That is why the PLIA contracted with Freshwater Solutions to study the prevalence of the culprit, a schistosome, in Platte Lake. The rash is called a cercarial dermatitis, commonly known as Swimmers Itch.Īlthough the medical problem caused by Swimmers Itch in humans is only skin deep, it can be a real nuisance and even affect your property values. It was trying to find a key host in its life cycle, a bird and most likely a merganser. You and your family were the unintended target of a small parasite called a schistosome. They now are covered in dozens of red, raised bumps on their legs and feet. Your children just spent the day swimming on your beach. Understanding Swimmers Itch in Platte Lake The findings of that study were presented at the AugPLIA Annual Meeting. Patrick Hannington of the University of Alberta. That study was performed by Ron Reimink of Freshwater Solutions working with Dr. In 2019 we expanded our efforts to understand/control/limit incidents of swimmers itch by commissioning a study to determine the root cause of swimmers itch in Platte Lake via DNA analysis of snails, bird droppings, swimmer's itch parasites, etc.
Blankespoor from Swimmer Itch Solutions to do an analysis of swimmers itch activity at five key locations around the lake. All of these seemed potentially important in determining if a lake can be infected with swimmer itch. In 20 we participated in a study on swimmers itch with researchers from Oakland University who studied our lake for algae, chemicals, phosphorus, pesticides, snail colonies, zebra mussels and crayfish. PLIA has been studying swimmers itch since 2016. Platte Lake has swimmers itch, but it has historically been at very low level. The organization is concerned about anything that can alter the quality of the lake and that includes keeping an eye on swimmers itch. The reservoir water is clear and attracts divers.The ongoing surveillance of Platte Lake by the PLIA is not limited to simply monitoring phosphorus levels. Swimming is popular at the reservoir but check current conditions because swimmer's itch develops many summers. ATVs and sand buggies are allowed to operate on dunes in the park and in a larger dune area just outside of the boundaries. That spot is quite photogenic.Ī sand dune area extends down to the water and the reservoir has sandy beaches. Red sandstone formations protrude from the water near the marina. The park is open year-round and is a popular spot for winter camping. Concessionaires rent boats, watercraft, skis, boards and other items. Sand Hollow is a popular Utah State Park with very nice facilities including a paved boat ramp, docks, campground, restrooms and RV sites. Sand Hollow also offers a few bluegill, black crappie, sunfish and black bullhead.ġ8 miles east of St George, south of I-15, off Hyw 9. The largemouth usually begin to spawn in late April and that provides some of the best action of the year. As temperatures cool in September, fishing often becomes hot and stays good until the water gets cold. Action picks up in March and is good through May, then slows a bit during the hot months. Sand Hollow is one of Utah's best reservoirs for largemouth and it offers a good number of large fish. Our best success came using a crawdad style, between sundown and dark. We caught fish by working plastic jigs into the rocks along the dam. We fished Sand Hollow on Oct 3, 2019, and found good action for largemouth bass.
