Incumbent Kennewick Irrigation District board members are leading their challengers in the Tuesday election.
But one incumbent, Penny Hermanson, is in the lead with only 17 votes, according to the preliminary results.
Hermanson, who was elected to Position 4 last year after defeating Dean Dennis in the election, had 368 votes as of Tuesday evening. Dennis was at her heels with 351 votes.
Ballots were issued for 1,083 absentee votes, according to KID officials. Absentee votes will not be counted until Monday.
Meanwhile, in the Position 1 race, incumbent Kirk Rathbun, who is finishing his first three-year term, was in the lead with 567 votes.
His challenger, Jim Wade, a KID critic whom Rathbun defeated in the 2010 election, had earned 152 of the votes counted so far.
The KID board of directors will hold a meeting 9 a.m. Monday to count the remaining ballots and canvas the election.
