The lake level gauge was installed on  Nov 1st 2025 and is located North of the bridge on the east seawall. 

Gauge Zero = 1,208.86' (NAVD 88) based on 2026 survey. 

Data collection is ongoing. 

Water temperature monitor is 1 meter below the water surface south side of the lake in the bay near lot 84.
Data is automatically updated daily at 12 noon. 

Water clarity is measured at 3 locations on the lake, using a Secchi disc. The average of the 3 measurements is plotted.  Data is from 2 sources, 1) Nebraska Lake Management (NLM), 2) Lake Ventura Association Lake Management Committee (LMC). Higher clarity often indicates lower blue-green algae levels and a healthier ecosystem.
Secchi disc is a circular disk lowered in the water until it disappears used to measure water clarity or transparency, which indicates how deeply light can penetrate the water column.
