HEYBURN, Idaho - The Bureau of Reclamation will host a meeting to present streamflow forecasts and projected reservoir operations for Jackson Lake Dam and other Snake River reservoirs on May 15. The meeting will be held at the 49er Inn conference room, 330 W. Pearl Street, Jackson, Wyoming, at 5:30 pm.
The Snake River at Heise forecast is 114 percent of average, and the current storage in Jackson Lake is at 74 percent of capacity. The lake is expected to fill in June, with moderate demand for storage releases over the summer.
With the current snowpack, there may be potential for flooding downstream of Jackson Lake Dam due to possible significant inflows from tributaries. The tributaries also may experience high flows and flood flows. Caution is advised in these areas during the snowmelt season. Flood operations are determined by a forecast coordinated with the U.S. Army Corps of Engineers and Reclamation for the Snake River above Heise, Idaho.
The meeting facility is accessible to people with disabilities. Contact Darrin Fredrickson at (208) 678-0461, ext. 17, TTY 711, to request sign language interpretation for the hearing impaired or other auxiliary aids.

Jackson Lake Dam is located on the Snake River in Grand Teton National Park near Moran, Wyoming. The dam is part of the Minidoka Project and was originally constructed in 1911. Parts of the dam were later replaced in 1989 under the authority of Reclamation’s Safety of Dams Act.
