Today is June 3, 2026, and there’s quite a bit happening along the Lower Susquehanna River, especially at the Safe Harbor area. On this fine day, the river is flowing at approximately 25,000 cubic feet per second, but the good news is that this rate is expected to decrease over the next few days. Forecasts predict outflows of 23,500, 21,000, and 20,000 cubic feet per second. However, keep in mind, the water is looking a bit murky with a temperature hovering around 71°F.
At 7 AM, the elevation of Safe Harbor Forebay was around 226.80 feet above sea level. The regulation of Safe Harbor’s Lake Clarke is crucial, with levels maintained between 228.0 feet and 225.0 feet. It’s worth noting that conditions in the tailrace area below the dam can change dramatically in just minutes, so there’s a constant need for caution. If you’re thinking about diving in Lake Clarke, think again! The fluctuating water levels, shallow areas, and hidden debris make it quite dangerous. If you’re out there today or tomorrow, be aware that intermittent power generation is planned, and while there’s no spill scheduled, anything can happen at any moment.
Safety First
For boaters, there are some important safety reminders. It’s advisable to stay at least 1,500 feet upstream from the dam. Downstream, the area below the one-mile warning sign is off-limits for boats—safety is paramount! The Holtwood Dam also has its own regulations; currently, their Lake Aldred is being maintained between 169.6 feet and 167.8 feet. They plan to release water today, but tomorrow looks clear of any spills. Just remember, the water starts spilling over at 169.75 feet, so keep an eye on those levels!
If you’re looking for a fishing spot, both the Safe Harbor Fisherman’s Bridge and Holtwood’s Tailrace fishing area are open to the public. The Pequea Creek and York Furnace boat ramps are also operational. Just make sure to heed all the signs and safety information, whether you’re heading upstream or downstream. If you need assistance with portaging, a heads-up of at least 24 hours is required; you can reach them at 508-251-7744.
Understanding Safe Harbor
The Safe Harbor Hydroelectric Project (FERC No. 1025) is a significant player in the region, located at river mile 32 of the Susquehanna River between Lancaster and York Counties in Pennsylvania. This project kicked off back in 1930 and was brought to life in 1931 by the Safe Harbor Water Power Corporation. Fast forward to 2014, and Brookfield Renewable took the reins. The project features a massive 4,869-foot-long, 75-foot-high concrete gravity dam, an east-side powerhouse, a reservoir, a tailrace, and even a fishway to help our aquatic friends navigate.
Lake Clarke, part of this project, stretches about 10 miles upstream. It’s fascinating how this facility operates under the FERC license No. 1025, which was issued by the Federal Energy Regulatory Commission. Currently, the Safe Harbor Water Power Corporation is gearing up to apply for a new license through the FERC’s integrated licensing process—important for maintaining its operations. The existing license, however, is set to expire on April 22, 2030.
With all this information, it’s clear that while the water may be beautiful, it comes with its challenges and risks. So whether you’re fishing, boating, or simply enjoying the view, make sure to stay informed and safe!
