Please be advised that high-water conditions have washed away normal warning devices (buoys) at Safe Harbor & Holtwood Dam.
Once conditions return to normal and it is safe to do so, the warning devices will be re-installed.
Please use additional caution when on the river. Pay attention to your surroundings and respect all signage.
Also, due to these conditions, the flashboards at Holtwood Dam were washed away. As a result, please expect low water levels until replacement work can take place.
Hello, This is the Lower Susquehanna River update for Thursday August 16, 2018. The current river flow into Safe Harbor is approximately 230,000 cubic feet per second and increasing. The condition of the water is murky and 73 degrees Fahrenheit. There was 0.0 inches of precipitation reported at Safe Harbor between 7 am yesterday and 7 am today. The forecasted average daily river flows into Safe Harbor for the next three days are 199,800, 126,800 and 103,500 cubic feet per second. The Safe Harbor forebay elevation at 7 am was approximately 226.85 feet above mean sea level. The elevation on Safe Harbor’s Lake Clarke is scheduled to be regulated near the top level of 227.2 feet and 3.0 feet below the top level for today and 3.0 feet below for tomorrow. Below Safe Harbor, the tailrace area can vary several feet in a matter of minutes during normal operating conditions. Be aware of this danger and pay close attention to varying water levels at Safe Harbor Dam. Be aware that diving into the waters of Lake Clarke is dangerous due to fluctuating lake levels, shallow waters, river currents, and submerged debris. Safe Harbor is scheduled to generate power intermittently today and tomorrow. Safe Harbor is scheduled to spill water today and tomorrow. Spill can occur at any time. Please be aware of this danger. Boaters, please remain at least 1500 feet upstream of the dam for your safety. The elevation of Holtwood’s Lake Aldred is scheduled to be regulated between a top level of 174.6 feet and 172.5 feet for today. Due to recent high flows, the flashboards and upstream buoys at the Holtwood Dam are missing. Lake levels will be lower than normal during this time. Please exercise extreme caution when boating on Lake Aldred. Once river flows permit, repairs will be made to restore normal lake levels. Holtwood is scheduled to spill water over the top of the dam today and tomorrow. Spill can occur at any time. Again, please be aware of this danger. Spill begins at 164.5 feet above mean sea level. Please stay off the rocks below the Holtwood dam or you could easily find yourself trapped by rising water. Boaters should avoid the area downstream of the 1-mile warning tower in the river. Portage access users must keep to the East shore (river left) and use caution. A portage phone at the boat ramp is available for portage assistance. Please keep in mind that all hydroelectric power generation schedules, as well as lake elevations, are subject to change at any time without notice. The Safe Harbor Fishermen’s bridge is open to the public. Holtwood’s tailrace fishing area is open to the public. Pequea Creek and York Furnace boat ramps are closed due to high flows. Boaters should read all signs and information that alert boaters about safety issues both upstream and downstream of the dam and portage access. Boaters are urged to use caution and avoid boating in the lower end of Lake Aldred within 1 mile of the Holtwood dam. For portage assistance, a minimum of 24 hours’ notice is required to ensure safe portage around the dam. Please call 508-251-7744 to coordinate. Thank you and have a Safe Day.
