Inter-Fluve, Inc.

Inter-Fluve, Inc., a Hood River, Oregon–based employee-owned Subchapter S corporation, delivers aquatic ecosystem restoration engineering, habitat program design, and water infrastructure consulting to federal agencies as a prime contractor, with 100% of recent awards in the prime role across 152 total awards with combined potential value of $3.18 billion. The firm competes predominantly on Total Small Business set-asides and full-and-open procurements, with the set-aside posture recurring across Bureau of Reclamation indefinite delivery contracts but not required for most delivery orders issued under those vehicles.

Inter-Fluve's customer concentration is extreme and skewed by vehicle ceiling values. The Bureau of Reclamation dominates by award count, with 121 of 143 named awards (94% coverage) carrying $74.2 million in combined potential value; however, the National Oceanic and Atmospheric Administration anchors the dollar ranking with 7 awards carrying $3.05 billion in combined potential value, nearly 96% of the vendor's total pipeline. That disparity reflects the $50 million single-award NOAA indefinite delivery contract for Regional Architect-Engineer Environmental Services in the Northeastern U.S. Atlantic and Great Lakes region, effective through August 2028, against which only four delivery orders have been placed to date (totaling roughly $469 thousand). In contrast, Reclamation's two $12 million single-award indefinite delivery contracts—one for Tributary Habitat Program Architect-Engineer services in Oregon and Washington (through January 2029), the second for Idaho services (through November 2028)—are the operational core of Inter-Fluve's business. The Reclamation vehicles have issued 58 and 24 task orders respectively under the Oregon/Washington and Idaho contracts, with individual delivery orders ranging from $3,500 to $495 thousand and anchoring habitat restoration and river engineering projects across the Pacific Northwest. A $50 million USDA Forest Service Land Management Integrated Resources blanket purchase agreement (effective through March 2033) carries no reported task orders in the source snapshot.

Capability work exemplifies the aquatic-ecosystem-restoration-focused portfolio. Representative Reclamation delivery orders include the $453,362 New Lemhi River Ranch Habitat Project (design and environmental services), the $316,938 Mid-Lemhi Hayden Reach Habitat Project (80% and final design and construction support), the $182,422 All Fires Fremont-Winema stream surveys under USDA Forest Service's Land Management Integrated Resources BPA, and the $200,000 NOAA time-and-materials order for regional architect-engineer environmental services in the Northeast Atlantic and Great Lakes region. Services span preliminary design, 30-percent, 60-percent, 80-percent, and final design phases; construction observation and support; GIS analysis and hydraulic modeling; environmental compliance assistance; surveying; feasibility evaluations; and project documentation. Work is performed in Hood River, Oregon, and at project sites throughout Oregon, Washington, Idaho, and (on the NOAA contract) the Northeastern U.S. Atlantic and Great Lakes region, with administrative oversight from the Hood River headquarters.

Activity has remained steady, with 16 awards in 2022, 19 in 2023, 28 in 2024, and 15 in 2025; the 2026 count of 4 awards reflects the recency of the snapshot. Sixteen awards (combined potential value $5.2 million) reach ultimate completion within the next twenty-four months and face recompete risk. The portfolio is heavily weighted toward architecture and engineering services: 130 of 152 awards carry engineering-services NAICS, and 97 awards carry the Architect and Engineering–General landscaping and design PSC code. Inter-Fluve does not sub-contract; it operates as a 100-percent prime across all awards and holds no named subcontractor relationships in the source data.

Service Contract Inventory data, which captures federal service contracts above the $150,000 threshold and thus reflects a strict subset of Inter-Fluve's federal revenue, shows SCI-reportable invoicing of $267 thousand in FY2022, $544 thousand in FY2023, and $696 thousand in FY2024, across roughly 0.1 FTEs per year. Government-paid hourly rates on SCI-reportable federal services work run a median of $3,404.19 per hour, with senior labor pricing through $5,814.47 per hour and lower-end rates around $1,179.57 per hour. The firm delivers no subcontracted hours on SCI-reportable prime contracts, indicating self-delivery of all labor on those awards. SCI figures understate total federal services revenue—they exclude goods orders, micro-purchases, contracts below $150,000, and any classified or non-federal work—and do not reflect the roughly $22.3 million in obligated dollars across the full award portfolio, which sits at only 1% of the combined $3.18 billion ceiling.
