Grant applicant resources 

We will offer a series of applicant workshops across the state in Fall/Winter 2023 to provide information to potential grant applicants about the process and purpose of the grants.

Pre-application meetings will be offered by request in Fall/Winter 2023. Pre-application meetings are an opportunity for potential applicants to discuss the details of their project with Ecology staff before applying. These meetings are required for projects that have a water right acquisition component and optional for any other project.
