Citizen volunteers: Wendell Shafer until 1998, Terry Smith 1999 until March 2008, Bob Price since then. Gull Lake, Kalamazoo and Barry counties, MI (southwest of Hickory Corners, MI) Area 2040 acres Maximum depth ~110 feet Elevation ~881 feet above sea level Ice cover in this lake system has been monitored by local citizens, assisted since 1998 by Stephen Hamilton. The lake drains via an outflow stream into the Gull Creek system. In recent years the lake has been declared ice-covered when it was more than half frozen for more than a day, as viewed from the midpoint at Kellogg Biological Station. It is uncertain how brief ice cover periods and partial ice cover were dealt with in the record prior to 1996. Contact: Dr. Stephen K.

Water levels in the Lower Crooked lake system and associated ponds have been monitored by Stephen Hamilton since 1996. The system is isolated and does not drain into a stream. These data represent the main lake. At higher water levels (>923 feet above sea level), water levels in this lake are generally in equilibrium with levels in Upper Crooked Lake. Below that level a wier at the Parker Road causeway between the lakes may result in a lower water level in Lower Crooked Lake. In 1996 the staff gauge was surveyed (NVD 88 datum) to a benchmark near the junction of Milo Rd and 3 Mile Rd, and referenced to the benchmark at the NE corner of Parker and Milo Rd. The latter has recently been verified and the two agreed well. All gauges are surveyed annually to an nearby upland rebar marker as a check for vertical displacement. Lower Crooked Lake has two gauges and from time to time both gauges are read on the same day. Water levels in Fair Lake have been monitored by local citizens, assisted since 1996 by Stephen Hamilton. The lake drains via a small outflow stream into the Augusta Creek system. Water levels are measured relative to an arbitrary datum and expressed as cm above the minimum level in the record (15 Nov 1964). The gauge datum elevation has not been surveyed. In recent years the gauge has been surveyed periodically to a nearby upland rebar marker as a check for vertical displacement. Ice cover has also been monitored over the same period.
