(iii) by striking subparagraphs (A) through (C) and inserting the following:

“(A) airborne laser altimetry;

“(B) imaging spectroscopy;

“(C) integrated physics-based snowpack and hydrologic modeling; and

“(D) other technologies that the Secretary determines are likely to provide more accurate or timely snowpack measurement data commensurate with operational water management needs.”;

(B) in paragraph (2) by inserting “, including the National Oceanic and Atmospheric Administration and the Natural Resources Conservation Service,” after “other Federal agencies”; and

(C) by striking paragraph (3);

(3) in subsection (e)—

(A) in paragraph (1), by striking “After submitting the report required under subsection (d)(3), the” and inserting “The”; and

(B) by striking paragraph (2) and inserting the following:

“(2) FOCUS.—The program shall focus on activities that will maintain, establish, expand, or advance snowpack measurement and integrated modeling, with an emphasis on—

“(A) enhancing activities to achieve improved snow and water supply forecasting results that are more responsive to changing weather and watershed conditions;

“(B) real-time integration of activities described in this section with water supply forecasts;

“(C) activities in river basins where activities described in this section can produce snow and water supply data to inform water management decisions, including interstate water management decisions; and

“(D) building program partners’ capacity to implement and adapt to the new measurement and forecast capabilities enabled under this program.”;

(4) in subsection (f)—

(A) by striking “of this Act” and inserting “of the Snow Water Supply Forecasting Reauthorization Act of 2025”;

(B) in paragraph (1)—

(i) by striking “and sub-basins”;
