The Mattawa Fire Department also includes the Mattawa Volunteer Firefighters Association which meets every third Wednesday of the month. If a volunteer firefighter wants to join the association there is a $10.00 yearly membership fee. Elections for the executive are held every second September for the following positions: President, Vice President and Secretary/Treasurer.
The association includes several committees that do fundraising through special events such as the Christmas parade in December, and the Voyageur Days bingo in July. The association also fundraises with the sale of Nevada tickets sold by the Mattawa Variety Store. The proceeds from fundraising enable firefighting equipment to be purchased, donations to be made to various community organizations, and bursaries to be awarded to students at the local schools.
