Lake Conroe History

Image title

One hour north of Houston you will find the reserve drinking water supply for the City of Houston.  A reservoir created by the San Jacinto River Authority and the City of Houston.  Lake Conroe was envisioned after a 7 year drought in the 1950’s with construction beginning in the late 1960’s and completed in January of 1973 with the lake being completely filled in October of that same year.

Here are a few facts about Lake Conroe and her dam.

Fun (unrelated) Facts:

After a trip to San Francisco last year – I was amazed by the bay and of course the bridge.  I wondered and began to study the size and depth of the San Francisco Bay – I was surprise to learn that while at it deepest point the bay is 365 feet (under the Golden Gate Bridge) the bay has an average depth of 43 feet. The northern and southern areas have average depths of 14 to 17 feet.  In some spots the water level is only 7 ½ feet during high tide and that is not limited to shoreline.  The bay must be maintained by frequent dredging to allow for large ships to pass.
