Lake Level Management
While PG&E owns the Lake, the water level is adjusted for several needs through the year. First of all, farmers need the water downstream. Around 1900, the corporation of ranch owners, Henry Miller and Charles Lux sued to stop the obstruction of the natural flow of water for the San Joaquin River and its branches. The suit resulted in the Miller-Lux Agreement. For Bass Lake this required the Lake's owner to decrease the Lake level to 60% of full by September 15th and 50% by November 1st each year. The Bureau of Water Reclamation monitors this agreement. For the last several years the Bureau has delayed the date of the agreement by 6 weeks allowing Bass Lake to remain fuller for recreation.
Bass Lake was completed in 1910 to protect property downstream. Now it generates 27 megawatts of power through 5 downstream power houses and is owned by Pacific Gas & Electric. It has developed into major resort and recreation facility. This Lake features year round full contact with boating, personal water craft, fishing & water sports. More history
