On the Spokane River, Frontage and Moorage Are Two Different Purchases

In May 2026, the Idaho Department of Lands denied an application from four adjacent riparian owners on the Idaho stretch of the Spokane River. They had asked to build what they described as a community dock system: four docks ranging from 1,262 to 2,268 square feet, eight boat lifts, two boat garages, one dock per parcel. The Director's Final Order, issued May 15, concluded the applicants were in essence seeking four oversized single-family docks. Three of the four would not have preserved the navigation corridor the agency uses to evaluate these applications. One would have narrowed the channel to 339 feet.

On the same area of river, a different community dock application had already been approved. Five docks, ranging from 75 to 154 feet in length, with the longest ones placed where the river is wider and could accommodate them.

Both properties have Spokane River frontage. Both sit on water the state considers navigable. Only one of them carries moorage.

The variable that decides riverfront value is not on the listing sheet

Buyers comparing riverfront listings tend to price frontage: linear feet, orientation, depth of the bank, whether the lawn runs to the water. That analysis is complete for a lakefront parcel and incomplete for a river parcel, because on the Idaho stretch between Coeur d'Alene Lake and Post Falls Dam, the right to put a structure in the water is a separate entitlement granted by the state, and it is granted or withheld based on a physical fact the seller does not control: how wide the river is directly in front of the lot.

Docks on navigable Idaho waters require an encroachment permit from the Idaho Department of Lands under the Lake Protection Act, Idaho Code Title 58, Chapter 13, and the administrative rules at IDAPA 20.03.04. Those rules were approved by the 2026 Idaho Legislature and took effect July 1, 2026. The standards are specific. A single-family dock is not to exceed 700 square feet or 10 feet in width, a two-family dock 1,100 square feet. The approach ramp maxes out at 6 feet. Structures may not sit closer than 10 feet to an adjacent littoral line without the neighbor's written consent.

Layered on top of the size standards is a navigation question. In hearings on this stretch of river, the agency has evaluated proposals against a 366-foot corridor, described on the record as a 66-foot unobstructed travel lane with a 150-foot buffer on each side. In the reach where a 74-slip community dock was contested in 2025, the channel width was cited as roughly 522 to 769 feet, narrowing to somewhere between 433 and 678 feet once docks were built. On a lake, those numbers are academic. On a river eight to nine miles long with two shorelines converging, they are the whole analysis.

The denial is the more instructive document. The hearing took place April 8, 2026, before Administrative Law Judge Leslie Hayes at North Idaho College's Molstead Library. None of the four applicants testified. Eight public comments came in opposing the application. IDL's Navigable Waters Resource Supervisor, Mike Ahmer, built a chord-method figure from the plat map to verify where the littoral lines actually fell. This is not a rubber stamp process, and it is not a process that runs on the calendar of a real estate transaction.

What the permit file should show before an offer goes out

The friction shows up in due diligence, not at the closing table, which is why it so often shows up too late. A permitted encroachment leaves a paper trail, and the trail has more steps than most buyers expect:

• The permit is recorded with the county recorder's office. A dock that exists without a recorded permit is a question, not an amenity.
• After construction, the permittee files a work completion report with IDL, and IDL inspects the structure to verify it complies with the permit terms and the standards.
• The permit describes specific dimensions. A structure that has been extended, widened or rebuilt beyond what was approved is no longer the structure that was permitted.
• Encroachments built before 1975 and not modified since may be permitted without a fee, but only with substantive documentation of age, including dated aerial photographs, tax deeds or similar records.
• Boat lifts, mooring buoys and shoreline stabilization are themselves permitted encroachments, and filing fees are cumulative.
• Dock permits on free-flowing river reaches are handled by the Idaho Department of Water Resources through its Stream Channel Protection Program rather than by IDL, so the jurisdiction depends on where the property sits.

There is also a lesson in the objection process worth carrying into negotiation. In the denied case, an objector withdrew after the applicants relocated one of the docks to provide an 80.5-foot setback. Design changes resolved a neighbor dispute before the hearing. Where an objection cannot be resolved informally, IDL holds a formal administrative hearing, and the timeline stops being predictable.

The water calendar is written in a federal license

The second thing riverfront frontage does not buy is a fixed water level, and August 2026 produced a headline that confused the point badly.

On August 13, the Spokane River ran dry for the second consecutive year along roughly a mile and a half from Barker Road down to Sullivan Road, about two weeks earlier than in 2025, according to Spokane Riverkeeper waterkeeper Jule Schultz. That stretch sits well downstream in Washington, below Post Falls Dam, in the free-flowing reach where the river depends on the aquifer. It is a real and serious story about drought. It is not a description of the water in front of Idaho riverfront homes.

"The problem with that is the mechanism was not designed to account for things like climate change."

That was Spokane Riverkeeper water protector Katelyn Scott, describing the license framework that governs flows out of the dam. Avista reduced releases from Post Falls Dam to the federally required minimum of 500 cubic feet per second beginning the week of August 7, 2026, in coordination with the Idaho Department of Environmental Quality and the Washington Department of Ecology, as hot and dry conditions pulled the lake down. Both Spokane and Kootenai counties are in severe drought, with Coeur d'Alene running about four inches below normal precipitation for the year.

Above the dam, the arithmetic runs the other way. Coeur d'Alene Lake is a natural lake with a restricted outlet, and once spring runoff recedes, closing the spill gates fills the stretch of river between the lake and the dam. Under the FERC license issued in 2009, the lake is held at a summer full-pool elevation of 2,128 feet from as early as practical in spring until the Tuesday after Labor Day, which this year falls on September 8. Reducing releases downstream is, in part, what keeps that pool where it is. Kootenai County's own guidance describes the pattern plainly: summer elevation is maintained through the first part of September, Avista then works to lower the lake about 7.5 feet by the end of January, and the lake runs on free-flow discharge from January until after runoff.

For a buyer, that translates into something concrete. The full-pool season on Idaho riverfront is a licensed season, not a weather season, and it ends on a date set years in advance. Owners are advised to secure docks and boats through the drawdown. A buyer touring in July is seeing the top of the range. A buyer touring in November is seeing something closer to the bottom.

What the county numbers hide

The Coeur d'Alene Regional Realtors June 2026 report put the Kootenai County single-family median at a record $565,000, up 3.9 percent year over year and 25 percent over five years. Through June 2026, 1,246 single-family homes had sold countywide, up 6.6 percent. Active residential listings stood at 1,082 as of July 6, down 10 percent from a year earlier, and homes averaged 82 days on market, down 13 percent.

Set that next to the asking side. Countywide median listing price reached $794,825 in June 2026, while city-level closed medians for the three months ending May 2026 ran near $574,656 in Coeur d'Alene and $524,686 in Post Falls. A gap of roughly $220,000 against the Coeur d'Alene closed median, and wider still against Post Falls, is not evidence of a collapse in negotiation. It is a mix effect. Waterfront, luxury and acreage inventory sits in the asking pool in disproportionate numbers.

Which is the point. Every figure above prices housing. None of them price moorage. Two riverfront listings can carry the same asking price, the same frontage, the same finish level, and one of them can hold a recorded, inspected, compliant permit while the other holds a hope that the corridor math works out. The 2026 case record shows the state saying no on the narrower reaches. That entitlement is invisible in a median and decisive in an appraisal conversation.

Why the corridor question is getting harder, not easier

Public use of this reach is expanding on purpose. The City of Coeur d'Alene purchased nearly 47 acres of former Atlas Mill riverfront in 2018 for $7,850,000, later growing the project to roughly 70 acres. About 24.5 acres became public open space with 3,780 linear feet of public shoreline, including the 12.5-acre Atlas Mill Park with its ADA swim area, ADA kayak launch, dog park and Centennial Trail access. The denied dock application sat directly across the water from that park, with its swim areas and its relic mill pilings.

Private density is arriving alongside it. Roughly 382 residential units are in the Atlas Waterfront pipeline with about 10,000 square feet of commercial space. Toll Brothers has listed 50 townhomes there starting around $794,000, with premium units above $1 million, while deChase Miksis and Edlen & Co. build 150 rental units on the west end.

More public shoreline and more households on the same corridor means more parties with standing to comment when an encroachment application is noticed. Existing permitted moorage on a narrow reach is, if anything, becoming harder to replicate.

Questions buyers ask late

A listing says the property has a dock. Isn't that settled? The structure existing and the structure being permitted as built are two separate facts. The permit is recorded at the county, the dimensions are specified, and a work completion report and IDL inspection follow construction. Those documents either match the structure or they do not.

If a neighbor objects to a new dock, is the application finished? Not necessarily. In the 2026 case on this river, an objection was withdrawn after the applicant relocated a dock to create an 80.5-foot setback. Unresolved objections trigger a formal administrative hearing, which adds time and uncertainty rather than an automatic denial.

Does the fall drawdown affect river frontage the same way it affects the lake? The stretch between the lake and Post Falls Dam is filled by dam operations after runoff and follows the same licensed calendar, with summer elevation held until the Tuesday after Labor Day. The free-flowing reach downstream in Washington behaves differently and is where this summer's dry-riverbed reporting originated.

If you are weighing a Spokane River property this fall, the permit file deserves the same scrutiny as the inspection report. Michaela Corcoran-Hall and the Corcoran-Hall & Co. team read these files before offers are written, not after. Request a Private Consultation.
