Program Objective

The objective of the Aquatic Ecosystem Restoration Program is to work cooperatively with states, Tribes, and other entities as they study, design and construct aquatic ecosystem restoration projects that are collaboratively developed, have widespread regional benefits, and result in the improvement of the health of fisheries, wildlife, and aquatic habitat through restoration and improved fish passage. As used here, “aquatic ecosystem” refers to freshwater and brackish water habitats such as lakes, ponds, rivers, streams, wetlands, swamps, and estuaries and the adjacent floodplains, riparian corridors, deltas, and shallow aquifers that interact with surface water.

Description

The Aquatic Ecosystems Restoration Program provides cost-shared financial assistance for the study, design and construction of aquatic ecosystem restoration projects that are collaboratively developed, have widespread regional benefits, and result in the improvement of the health of fisheries, wildlife, and aquatic habitat through restoration and improved fish passage.

Use of Funds

Allowed Uses

The Aquatic Ecosystem Restoration Program provides cost-shared financial assistance for the study, design, and construction of aquatic ecosystem restoration and protection projects that improve the health of fisheries, wildlife or aquatic habitat, including through habitat restoration and improved fish passage through the removal or bypass of barriers to fish passage (e.g., dams). All program funds are discretionary.

Required Documentation

Applicants proposing the study and design of a project that removes or modifies a dam in a manner that reduces storage or diversion capacity, must provide written consent of the owner of the dam. Applicants proposing the construction of a dam removal or modification project must a) identify any eligible entity that receives water or power from the facility that is under consideration for removal or modification, b) notify each eligible entity that the dam removal or modification project was requested, and c) not receive by the date that is 120 days after the date on which all eligible entities were notified, written objection from 1 or more eligible entities that collectively receive 1/3 or more of the water or power delivered from the facility that is to be removed or modified.

Matching Requirements
