Lewis Creek Reservoir is located approximately three miles west of Willis in Montgomery County, Texas. The reservoir was created by damming Lewis Creek, a tributary of the West Fork San Jacinto River, and serves primarily as a cooling pond for a nearby power plant, though it also offers some recreational opportunities.

The reservoir covers a surface area of about 1,010 acres at its normal elevation of 267 feet above mean sea level. It has a storage capacity of 16,400 acre-feet and a relatively small drainage area of 4.4 square miles. The earth-fill dam, completed in 1969, measures 12,836 feet in length with a maximum height of 54 feet.

The reservoir's size and purpose suggest it may offer calm waters suitable for flatwater paddling. However, paddlers should be aware that the primary function of the reservoir is industrial, which may impact water quality and temperature.

Located in the San Jacinto River Basin, the reservoir is likely surrounded by typical East Texas vegetation and wildlife, potentially offering opportunities for nature observation.

Paddlers should note that water levels in the reservoir are actively managed, with water purchased from Lake Conroe as needed to maintain desired levels. This could potentially affect paddling conditions and access points.

Before planning a paddling trip, it's best to contact local authorities or Entergy, the reservoir's managing entity, for current information on access points, any restrictions or regulations, and safety considerations specific to paddling on this industrial reservoir.
