Description

This RFP seeks a qualified individual or firm to conduct comprehensive hydrologic and water‑availability studies for the 15‑mile reach of the Colorado River in Colorado.

Budget estimate

$500,000 – $1,500,000

The solicitation does not disclose a contract value. Similar multi‑year hydrologic‑modeling contracts for state agencies typically range from $500,000 to $1,500,000, depending on scope, staffing level, and data‑collection requirements. Given the need for specialized Colorado water‑rights expertise, StateMod modeling, and a final deliverable report, a reasonable estimate is a mid‑six‑figure to low‑seven‑figure award.
