Comments:
Western grebes are and have been nesting at this lake in recent years, according to Ron Martin (2023). No specific years provided so estimated the range of 2018 to 2022 as active breeding lake though it could have supported nesting prior to this range. Martin (2023) states that water levels rose in the last 20 years and many lakes had a lack of grebes in the 80s and early 90s.

Comments:
Larry Igl confirms that Western grebe (or Western and Clark's grebe) colonies were at this lake in the past. He updated the years active as one or more years within the past 5 years via eBird as having Western grebes during the breeding season. Therefore to generate his original list of ND lakes and then update the years most recently surveyed/observed might include multiple years. He also thinks there are probably more ND lakes than is listed here that support grebe colonies.
