People do break the rules and camp too close to the water sometimes, but generally, yes, you need to camp a good distance from the water.
Here are the rules from the website (nps.gov/yose)
* The permit is only valid for the trip leader, trailheads, dates, and number of people specified on the permit.
* You must camp at least four trail miles from Tuolumne Meadows, Yosemite Valley, Glacier Point, Hetch Hetchy, and Wawona, and at least one air mile from any road. Camping is prohibited in the Dana Fork of the Tuolumne River.
* Group size is limited to 15 people or fewer, eight people maximum for any cross country hiking more than one-quarter mile from any trail. Stock use is limited to 25 head.
* Choose a previously impacted campsite at least 100 feet (30 meters/40 paces) from any water source or trail.
* All human waste must be buried at least six inches deep and at least 100 feet from water sources, camp areas, and trails.
* Do all washing at least 100 feet from water. Do not put any soap in water (even biodegradable and natural soap pollutes).
* Carry out all trash. Do not burn or bury toilet paper or trash.
* Wood fires are allowed in existing fire rings only, and prohibited above 9,600 feet in elevation. Use dead and down wood only.
* Proper food storage is mandatory. Allowed bear-resistant food canisters are required in all areas of Yosemite. Cleanup of food and debris if a bear gets your food is your responsibility. Report any bear incidents and sightings to the nearest ranger. You can also report bear sightings by calling the Save-a-Bear Hotline at 209/372-0322.
You won't have issues with the minimum elevation - most places you backpack will automatically be above that.
