Did the lake come back? That's the question regulars at the Henrico boat ramp on Waterfront Road have been asking each other since spring, when a low-water alert went out and every dock on the north end of the lake seemed to sprout an extra two feet of exposed pilings overnight. Late August is usually when people stop worrying about water levels and start worrying about the last good weekends of the season. This year the two questions collided, and the answer to the first one turns out to be more interesting than a simple yes.
The alert nobody forgot
Back in April, Dominion Energy sent word through the Lake Gaston Association that lake levels were running low. The message was blunt: levels had been sitting in the lower half of the normal range, spawning flows were about to start pulling more water downstream, and rain wasn't coming. Dominion's operating license lets the lake drop as low as 198 feet for short stretches, and that's roughly where things were headed. Anyone who launches from the Henrico ramp with any regularity remembers that stretch. Ramps that are usually a non-issue got shallow fast, and the exposed mud at low tide made the boring math of feet and inches suddenly personal.
The drought behind that alert didn't clear up quickly either. As of mid-July, the U.S. Drought Monitor still had Warren County classified as being in severe drought, months after the original low-water warning went out. If you were only tracking the news, you'd expect the lake to still be down.
It isn't.
What the gauge actually says in early August
By August 9, the lake gauge had Lake Gaston sitting at 199.88 feet, a tenth of a foot below the 200-foot full-pool mark, and on a rising trend over the prior week. A separate reading around the same window put it at 199.86 feet, fluctuating by hundredths of a foot day to day rather than the multi-foot swings that made spring so noticeable. In practical terms, the lake spent the back half of summer climbing back to essentially full pool while the county it sits in was still, on paper, in a drought. That's not a contradiction so much as a reminder that Lake Gaston isn't rain-fed in the way a lot of people assume. Dominion and the Army Corps of Engineers manage releases from the upstream Kerr Reservoir into Gaston under a federal license, and the coordination between the two systems can put water back in the lake even when local skies stay dry. For a Henrico ramp regular, the takeaway is simple: if you were avoiding the ramp because of what you saw in April, that particular problem is behind you.
The other clock, running on its own schedule
Here's where it gets less simple. The low water and the lake weeds are not the same story, and they don't run on the same timeline, which is why a boat that launches clean from the Henrico ramp this week can still nose into a mat of vegetation two coves over.
The Lake Gaston Weed Control Council targeted 326 acres for hydrilla-specific treatment this year, applied in three consecutive monthly rounds: May 19 to 21, June 16 to 18, and July 14 to 16. Crews from PLM Lake & Land Management Group did the work from boat-mounted units, broadcasting herbicide pellets along the shoreline in the mapped treatment zones. Those rounds are done for the season. Separately, the council approved treating up to 500 acres for lyngbya, the mat-forming algae that can leave a foul smell and skin irritation where it colonizes, using a chelated copper-based algaecide. That algaecide has a distinct bright blue tint right after application, so if you've seen a patch of oddly colored water near a treated cove and wondered what happened, that's almost certainly it, and it carries no restriction on swimming, fishing, or boating.
The part that catches people off guard is the timeline for actually seeing results. Effective lyngbya control takes four to six consecutive monthly algaecide treatments, and that's spread over multiple years, not one season. Hydrilla management leans on a second, slower tool alongside the herbicide: sterile grass carp that keep grazing on regrowth long after the boat-mounted crews have moved on. Dominion funded roughly 1,300 of those carp for stocking in 2026. So even though the herbicide calendar wrapped up in mid-July, the actual cleanup is still working through mechanisms that don't have a fixed end date. If a cove near the Henrico ramp still shows vegetation in late August, that's not a sign the program failed. It's a sign you're looking at year two or three of a multi-year protocol, with grass carp quietly doing the slow part of the job.
There's one practical wrinkle worth knowing if you draw irrigation water anywhere near a treated shoreline: the herbicides used for hydrilla carry water-use restrictions on irrigation for a period after application, unlike the copper-based algaecide used for lyngbya. If your property backs up to a spot that got treated this summer and you irrigate from the lake, it's worth checking before watering the lawn right after a treatment week.
Reading the lake like a local, not like a headline
Put those two clocks together and the practical picture for someone launching from Henrico this month looks like this. Water depth at the ramp is not the problem it was in April. The lake is close enough to full pool that the low-water anxiety from spring can be set aside for now. What you might still run into is patchy vegetation in specific coves, not because anything is broken, but because the multi-year weed program is still mid-cycle in some of those spots. Checking the treatment map on the Lake Gaston Weed Control Council's site before you head out tells you more than guessing from the dock ever will.
That's really the whole point. A single glance at green water or a shallow-looking ramp gets read as one emergency, when it's actually two separate, well-documented processes overlapping at different speeds. Once you know that, you stop treating every patch of vegetation as new bad news and start reading it as the middle of a plan that's already three years into working.
The reward for reading it right
None of this changes what happens after you load the boat back on the trailer. Washburn's Marina is still the stop people default to, gas dock, tackle, and burgers that regulars will tell you are the best on the lake if you ask around at the ramp. And if you'd rather sit down than eat standing at the dock, Gettin' Sauced in the City opened its brick-and-mortar location on River Road after eight years running the food truck version, serving the same homemade Italian recipes the owners, a Marine Corps veteran and his wife, built their reputation on before they ever had four walls.
The lake did come back. The coves are still catching up. Knowing the difference is what makes the rest of your Saturday easier to plan.
