Hydrology

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

Data collection is ongoing. New readings are posted weekly. 

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.
