SECTION 1. SHORT TITLE. 
This Act may be cited as the ‘‘Snow Water Supply 
Forecasting Reauthorization Act of 2025’’. 
SEC. 2. SNOW WATER SUPPLY FORECASTING PROGRAM. 
The Snow Water Supply Forecasting Program Au-
thorization Act (43 U.S.C. 1477) is amended—
(1) in subsection (c)(2)—
(A) in subparagraph (A), by striking ‘‘cul-
minating in the report required under sub-
section (d)(3)’’ and inserting ‘‘with an emphasis 
on deployment of technologies that provide inte-
gration of snowpack measuring and modeling’’; 
and 
(B) in subparagraph (B), by striking 
‘‘after submitting the report required by sub-
section (d)(3),’’; 
(2) in subsection (d)—
(A) in paragraph (1)—
(i) in the heading, by adding ‘‘WITH 
INTEGRATED MODELING’’ after ‘‘DATA’’; 
(ii) by striking ‘‘emerging technologies 
for snowpack measurement, such as’’ and 
inserting ‘‘technologies that provide com-
plete integration of accurate, timely, and 
spatially complete snowpack measurements
and models, including the integration of’’; 
and 
(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 commen-
surate with operational water management 
needs.’’; 
(B) in paragraph (2) by inserting ‘‘, in-
cluding the National Oceanic and Atmospheric 
Administration and the Natural Resources Con-
servation Service,’’ after ‘‘other Federal agen-
cies’’; 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 insert-
ing the following:
‘‘(2) FOCUS.—The program shall focus on ac-
tivities that will maintain, establish, expand, or ad-
vance snowpack measurement and integrated mod-
eling, with an emphasis on—
‘‘(A) enhancing activities to achieve im-
proved snow and water supply forecasting re-
sults that are more responsive to changing 
weather and watershed conditions; 
‘‘(B) real-time integration of activities de-
scribed in this section with water supply fore-
casts; 
‘‘(C) activities in river basins where activi-
ties described in this section can produce snow 
and water supply data to inform water manage-
ment decisions, including interstate water man-
agement decisions; and 
‘‘(D) building program partners’ capacity 
to implement and adapt to the new measure-
ment 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 Reau-
thorization Act of 2025’’; 
(B) in paragraph (1)—
(i) by striking ‘‘and sub-basins’’; 
(ii) by striking ‘‘technologies’’ and in-
serting ‘‘and integrated modeling tech-
nologies’’; and 
(iii) by striking ‘‘technology used’’ and 
inserting ‘‘application, outcome, and data 
resources used’’; and 
(C) in paragraph (2), by striking ‘‘or sub-
basin’’; and 
(5) in subsection (g), by striking ‘‘$15,000,000, 
in the aggregate, for fiscal years 2022 through 
2026’’ and inserting ‘‘$3,000,000 for each of fiscal 
years 2027 through 2031’’.
