This is the Lower Susquehanna River update for Tuesday February 20, 2018.

The current river flow into Safe Harbor is approximately 126,500 cubic feet per second and decreasing. The condition of the water is murky and 38 degrees Fahrenheit.

There was 0.01 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 120,800, 132,500 and 124,000 cubic feet per second. The Safe Harbor forebay elevation at 7 am was approximately 227.6 feet above mean sea level.

The elevation on Safe Harbor’s Lake Clarke is scheduled to be regulated near the top level of 228.0 feet and 1.0 foot below the top level for today and 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 continuously 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.

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 169.75 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.
The Pequea and York Furnace boat ramps are currently open.  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.  Please contact Sickman's Mill LLC at: mail at or by dialing 717-419-4799
