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 specific to their state or territory.

The Connecticut Institute of Water Resources (CTIWR) uses the Base Grant to primarily fund freshwater related research and information transfer projects 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 (late September).
    • Full proposal invitations announced (first week of October).
    • Invited full proposals due (first week of November).
  • Full proposals sent out for external technical reviews (mid November).
  • Full proposals evaluated and selected for funding during the CTIWR Advisory Board meeting (mid December).
  • Proposals approved for funding announced (first week of January).
  • Final proposal package submitted to the USGS by CTIWR (mid January).

  • Total funds made available for individual projects through the 104B Program varies from year to year. We request a cap of $25,000 of federal funds per project. One year projects are preferred. Two year projects are acceptable, however, second year funding is not guaranteed. Any projects requiring two years must be proposed as two separate one year projects (the first year submitted now (FY 2021) and the second year submitted next year for FY 2022).
  • Federal funds must be matched at least 2:1 with non-federal dollars (every $1 federal funds requested must be matched with $2 from non-federal funds).


  • Principal Investigator must be at an accredited institution of higher learning in Connecticut to apply.
  • All PIs must submit their pre-proposal to the Connecticut Institute of Water Resources (CTIWR).
