Where Is Lake Conroe Located on a Map?

Lake Conroe is primarily located in Montgomery County, with a smaller portion in Walker County. It is around seven miles northwest of Conroe. Montgomery and Willis are other cities close to the lake. The lake is about one hour’s drive north of Houston.

Is Lake Conroe a Natural Lake?

Lake Conroe is one of many reservoirs in Texas that were conceptualized after the historic seven-year drought that occurred in the 1950s. The goal was to avoid water shortages like the ones experienced during the drought by creating water supply developments. The lake provides an alternative water supply source for the city of Houston which has a population of 2.31 million as of 2023. 

Since 1937, the San Jacinto River Authority (SJRA) has been responsible for the conservation and development of water resources in the San Jacinto River basin. Responsible for seven counties, they also manage 27 canal systems that provide water to industrial clients, drinking and wastewater for The Woodlands, implement flood control, as well provide soil conservation resources to ranchers and farmers.

How Was Lake Conroe Created?

Conroe Dam is the result of an earth-fill embankment that is 11,300 feet in length. The dam’s highest elevation is 212 feet above mean sea level and has a managed emergency spillway located at the center of the embankment. At its current levels, it resides 82 feet above the previous riverbed that existed before the dam’s construction. 

The project began in 1968 and was completed by 1973, which is when Lake Conroe was filled. The project was designed by Freese, Nichols, and Endress Engineering Inc. and executed by H.B. Zachery Company. The lake and dam are managed by the San Jacinto River Authority which, along with the City of Houston, owns the water rights to the lake.

What Surrounds Lake Conroe?

Surrounding beautiful Lake Conroe in the northwest region is the Sam Houston National Forest. It is one of four National Forests in Texas. Owned by the U.S. Dept of Agriculture as well as privately owned land and small farms, this 163,037 acres of forest spans Walker, Montgomery, and San Jacinto counties. There is evidence that human occupation dates back more than 12,000 years after various archaeological sites were discovered within the forest.

These lands were home to the Atakapa, an indigenous group of hunter-gatherers who may have even practiced some type of agriculture. Due to disease and the strain of European settlers, the Atakapa were extinct by the early 1800s. Today there are sites, structures, and cemeteries still present in the forest which you may encounter while hiking.
