The Raquette River staircase: a North Country river run as one power system

I. How the staircase works

Start with the physics. The Raquette drops something on the order of a few hundred feet from the Adirondack plateau to the St. Lawrence lowlands, and that fall is what the dams turn into electricity. A hydroelectric development (a dam, a pond behind it, and a powerhouse with turbines) captures the height the water loses as it passes, so the more drop and the more water, the more power. On the Raquette the builders stacked many modest drops instead of one tall dam.

Most of the chain runs on the river's natural flow, passing water through as it arrives, which means output rises and falls with rain and snowmelt. Near the top of the developed reach, Carry Falls Reservoir works as the system's storage, holding water back in wet months so the plants below can keep running in dry ones. That is why a drawdown at Carry Falls changes paddling and fishing far downstream: it is the one big lever on an otherwise run of the river system.

II. One license, many dams

Underneath the concrete is a single piece of paper. The Federal Energy Regulatory Commission, or FERC (the federal agency that licenses most non-federal hydropower), treats much of the developed Raquette as one licensed project under a single operator rather than as separate plants. At last public report the chain is run by Brookfield Renewable through its United States hydro subsidiaries, after long decades under utility ownership.

A federal hydropower license runs for a multi-decade term, often roughly thirty to fifty years, and when it nears its end FERC opens a relicensing process. If you want the specifics for the dam near your road, FERC's eLibrary holds the license, the project number, and every public filing; search the project name and sort by date. We are not printing a docket number here on purpose, because the right one is the one you confirm yourself in that record.

III. What relicensing puts on the table

Relicensing is where a century-old river machine gets re-examined against current rules. The big questions are usually flows (how much water must be released below each dam, and when, so the stretch between developments is not left dry), fish passage (whether migrating fish can get around the dams), and recreation (portage trails, boat launches, and shoreline access the public can use).

New York adds its own gate: before FERC can relicense, the state issues a water quality certification (a finding under the Clean Water Act that the project will meet state water standards), handled here by the Department of Environmental Conservation. These reviews are slow and they slip. Studies disagree about how much flow a given reach needs, agencies and the operator negotiate, and a settlement can take years. If the honest answer to when is it depends, what it depends on is the studies, the comment record, and whether the parties settle or litigate.

IV. Worth watching this month

1. Whether a new relicensing or amendment filing for the Raquette appears in FERC's eLibrary, which you can check by searching the project and sorting by newest; this is the one that matters.

2. Any New York DEC notice opening a public comment window on a water quality certification for a Raquette development, since those windows are short and easy to miss.

3. A scheduled seasonal drawdown at Carry Falls Reservoir, which the operator typically posts and which is routine but changes access for miles downstream.

4. Any FERC scoping or study-plan notice, the step where public comments on flows and fish are formally entered into the record.

5. The NYISO seasonal outlook for the North Country region, useful context on how much this hydro counts toward regional supply, and mostly routine.
