"We know it's going to have a big impact on people's lives, but it's also showing why we need to renovate this park," Karyn MacNeill, director of Yarmouth Community Services, told the Portland Press Herald back in April, when the town confirmed Royal River Park would close for the entire summer. Residents who filed that quote away and circled mid-September on the calendar are about to find out that the park reopening and the construction disappearing from view are not the same thing.
Royal River Park closed in mid-May for a path renovation the town had been planning since 2016. A different project, a federally studied dam removal on the same river, started in late July and is still running heavy equipment along the bank as of this month. Both involve the word "Royal River." Both involve construction fencing near East Elm Street. Only one of them was ever going to be done by fall.
What Actually Closed in May
The park closure wasn't a surprise decision. Yarmouth Community Services staff flagged the paths as needing work back in 2016, and it took until this spring for design, permitting and bidding to catch up. Sixteen trees came down in March to clear the new route, and the bulk of construction began around May 18, taking offline a park that draws up to 3,200 visitors a month in summer, according to the Press Herald's April report.
The scope, laid out on the town's Royal River Park Updates page, covers rerouting sections of trail for better access, stormwater upgrades to fix drainage that was causing erosion, widening the path where the corridor allows, adding down-facing lighting along the stretch commuters use after dark to reach the bus stop, improving the scenic overlook, and replanting with low-maintenance landscaping. The tennis and pickleball courts near Rowe School were already repaved as part of the same budget and have been open since last summer.
One decision explains why this took a $1.2 million budget instead of a routine repaving. A cistern bridge along the route needed replacing, and a straight swap would have run about $200,000. Instead, the town designed a reroute around the cisterns that meets ADA and Maine DEP requirements at roughly half that cost. It's the kind of tradeoff that never shows up in a ribbon-cutting photo but explains why a "path renovation" needed nearly a year of engineering before a shovel went into the ground.
The money itself came from five places, according to the town's project page: a $452,000 matching grant from the federal Land and Water Conservation Fund, $265,000 from Yarmouth's tax increment financing account, $20,000 from a Village Improvement donation, $10,000 from the Tree Fund, and $450,000 from the Capital Improvement Plan, which the town had been setting aside for eight years specifically for this project.
The Press Herald's original reporting put the reopening target at "around mid-September," with a ribbon-cutting ceremony planned for sometime after that, once new vegetation goes in this fall or next spring. Anyone checking the park gate this week is arriving close to schedule. The formal celebration MacNeill described is still ahead.
The Other Project on the Same River
A few hundred feet away, a second effort is nowhere near finished. This one is the Bridge Street Dam removal, part of a larger Royal River restoration effort that Yarmouth has been studying and permitting for years under what the town calls its Section 206 project. It's a different scope, a different funding source and a different timeline than the park path work, even though both show up in the same stretch of riverbank.
The dam removal broke ground on July 22, 2026, and the town has been posting weekly construction logs since. Crews from Linkel Environmental Construction spent early August removing the Denil fishway and cutting sections of penstock. By the second week of September, according to the town's own project updates, the crew was disassembling the concrete dam and removing sediment. The week of September 14 through 18 brought continued demolition on the river-right side near the old pump station, including hand removal of concrete on the ledge, while equipment began mobilizing to river-left to prepare for removing granite blocks. This is not a project winding down. It's a project moving into its next phase.
The reasoning traces back to why the dam exists at all. The East Elm Street Dam creates an impoundment that stretches roughly six miles upstream, all the way to Baston Park on Route 9 in North Yarmouth. Water sitting behind a dam warms in summer without mixing with cooler water below, and the town's own materials note that dissolved oxygen levels in that stretch don't meet the state's standard for a Class B waterway. In practical terms, the same materials note that E. coli counts near the Yarmouth History Center, right across East Elm Street from the park's main entrance, can get high enough in summer to rule out safe swimming.
| Royal River Park path renovation | Bridge Street Dam removal | |
|---|---|---|
| Started | March 2026 (tree clearing), May 18 (construction) | July 22, 2026 |
| Budget | $1.2 million (park and courts) | Backed in part by a $1 million grant from the Maine Natural Resources Conservation Program, approved January 2026 |
| Status as of late September 2026 | Targeted for completion around mid-September; ribbon-cutting still ahead | Active weekly demolition, crews working river-left into September |
| What it fixes | Trail surface, lighting, drainage, ADA access | Fish passage, water quality, river ecosystem health |
Reading the Entrances
Royal River Park has five ways in, and knowing which one you're using this month matters more than it did in July. The main entrance and parking lot sit on East Elm Street, directly across from the Yarmouth History Center, about 0.3 miles east of Main Street. That's the entrance closest to the path renovation's finish line. Mill Street offers a second way in from the village side. The Beth Condon Pathway connects near Rowe School, past the tennis and pickleball courts that have already reopened. Forest Falls Drive links in via a pedestrian bridge.
The fifth entrance, off Bridge Street, sits at the edge of the active dam removal site. If your usual habit was to enter or exit that way, expect to see the same construction equipment and fencing that's been there since July, regardless of what's happening with the rest of the park.
This split reality already showed up once this year in a way plenty of Yarmouth residents noticed without connecting it to two separate projects. The Yarmouth Clam Festival's Saturday morning race, normally routed through the park, had to move to public roadways for its 61st running in July because the park was closed. That's the kind of disruption a single project explains. The dam removal continuing into fall, after the park itself is meant to be usable again, requires knowing there were two projects running at once.
A Dam Built for Mills That Stopped Running a Century Ago
The reason there's a dam to remove at East Elm Street at all traces back to industry that hasn't operated there since the 1920s. Mills lined this stretch of the Royal River as far back as 1805, when a grist mill, a carding mill and a fulling mill shared the site. The Yarmouth Paper Company built there in 1864, burned in 1870, and was rebuilt two years later as the C.D. Brown Paper Company before being renamed the Forest Paper Company in 1874. By 1909, it was the largest soda pulp mill in the world, employing 275 people across ten buildings, some of them spanning the river to what's still called Factory Island. The mill closed in 1923 and burned again in 1931.
The brick remnants and interpretive signage along today's paved loop point to that history, but the dam itself outlasted the industry it powered by a full century. Removing it now isn't undoing something recent. It's finishing a transition the mills themselves started when they shut down.
What This Means for the Rest of Fall
The park path project has a defined end point and a ribbon-cutting still to come. The dam removal doesn't have that same clean finish line yet, at least not one the town has published. For anyone whose daily walk, run or dog loop runs through this stretch of Yarmouth, that means the return to normal isn't a single date on a calendar. It's the path reopening on one timeline while a different piece of the same river keeps changing shape on its own.
Watching a small town work through two overlapping public projects this closely, weekly construction log by weekly construction log, is the kind of detail that only shows up if you're paying attention to Yarmouth the way you'd pay attention to your own street. Elise Kiely follows this village that closely because it's the same village she works in every day.
