USGS 104b Program

Annual Base Grants

Under the provisions of section 104 of the Water Resources Research Act of 1984 annual base grants (104b) are awarded to the Institutes or Centers that have been established in each of the 50 states, the District of Columbia, Puerto Rico, the U.S. Virgin Islands, and Guam. The annual base grants help each Institute or Center to plan and conduct applied and peer reviewed research on water resource issues.

The Connecticut Institute of Water Resources (CTIWR) uses the Base Grant to primarily fund freshwater related research by investigators from Connecticut universities and colleges on problems of importance to Connecticut and the Northeast Region. The CTIWR uses a pre-proposal and invited full proposal process to select research projects for funding. The general schedule is as follows:

  • Call for pre-proposals announced (early September).
  • Pre-proposals due to CTIWR (first week of October).
  • Invited full proposals announced (second week of October).
  • Invited full proposals due to CTIWR via (first week of November).
  • Full proposals sent out for external technical review (mid November).
  • Full proposals evaluated during the CTIWR Advisory Board meeting and appropriate proposals selected for funding (mid December).
  • Proposals approved for funding announced (first week of January).
  • Final proposal package submitted to the USGS by CTIWR (mid January).
