Welcome to the world of teenagers! Set an expectation of grades. If any one grade drops below that then she should be grounded until that grade comes back up. We do this with my 13 year (second teen I'm dealing with). He can't go below a C.
Now, when grounding you need to ground the child on what will motivate them to get off grounding. My 21 year old didn't care about being grounded. He'd just sit there and play with a lint ball and be happy, lol. So we adjusted his grounding to include extra chores that he did not like. After all, grounding should make the child happy, but unhappy to motivate them to do better. With my 13 year old he hates being grounded cuz he's an outside kid, but he'll go in the basement where his room is and play on the video games, so having no video games is part of being grounded for him.
We can track his grades online and see when his grades go up and down and individual homework as well can be tracked. Homework is the killer for teens! My son has a planner that must be signed every night and we check off everything as we see it's done. We must SEE that it's done. We cannot go by his word that it's done but in his locker or whatever. We will notate that in his planner so the teacher and us can see if he's lying or not. If he lies he gets a day of grounding because lying will never be tolerated in this house. For every piece of homework that is not turned in on time gets a day of grounding. And they give 50% off if it's one day late so many kids figure "why bother". But we don't care if the work if turned in a week late. The work WILL be done and WILL be turned in, even if we already know he'll get a zero on it to teach him to follow through on his responsibilities. Also, collect all email addresses of each and every teacher of your teen at the school's web site and have constant contact with every little thing that goes on. Some response fast, some slow, some not at all. Just keep after them. After all, this is your child's education we're talking about.
So, I would sit down and have a meeting with your daughter. Write down a list that she will go by from now on and the consequences that will follow, good and bad. (good grades and good responsibility means freedom and trust, bad grades and poor responsibility means grounding and lack of freedom and trust)
1. She will write down all homework from each class on a daily basis. (if a planner isn't provided by school, buy her a notebook just for homework)
2. Her planner will be checked every night to be sure work is complete and Mom must SEE the completed work, notating anything missing to the teachers who should read this. (or email teachers on missing work so they're aware so the child knows everyone is communicating and nothing slips through the cracks)
3. Grades dropping below your chosen level requires grounding until that grade is visible online as raised.
4. Missing homework will be an added day of grounding per item.
5. All work will be turned in complete whether late or not.
6. Contact will be kept will all teachers on a daily basis so everyone is in the triangle loop. (triangle = parents, student & teachers) Break one link and the students slips.
7. "Grounding" will be explained and can be modified as needed.
Always keep a calm tone and keep it "matter of fact". Don't get sucked into arguments or excuses. She'll know the rules. She didn't follow them. She knows the punishment. That's it. Meanwhile, keep everything else pleasant. Once the child has the punishment handed out, that's it, it's over. No reason to keep bringing it up or nagging. That's like punishing her over and over again. Hand out the punishment and move on. When she comes off grounding and you see grades going up, make as big a deal about the good stuff as the poor stuff. When you see some good things happening, maybe take her out for a treat, something extra, but never take her off grounding early. She must learn to follow through on responsibilities, all the way.
This is allot of work on the parents part but it can help keep her on track. There's nothing wrong to have her checked at school for any learning problems either that may not be easily seen. Getting the school counselor involved or putting her on an IEP temporarily for extra support is an option as well. If she's been diagnosed with depression then she should be seeing a counselor on a regular basis and keep them informed through email or phone as to what is going on and what new things you have implemented at home so they are part of the solution.
Good luck!
