Brenden, yes a picture would be a big help. Do you know if the pond keeps its water through summer? Paul said this above, but to elaborate a bit, the basics of clear water are:
1. Aeration - you need the water to circulate so that fish and plants will survive and the water will not stagnate. Lots of people buy a small, solar operated fountain to put out in the middle of the pond and it does the job.
2. Plants - marginal plants like irises and cannas that grow at the edges of the water (and sometimes are IN the water when it rises) will filter out a lot of stuff for you. Plants growing in the water like hardy water lilies (that will survive the winter and come back each spring to bloom all summer) will also filter stuff out of the water AND they will spread their leaves over the surface to shade the water in the warm months so that algae has a harder time to grow.
3. Fish - will eat algae and mosquito larvae as well as other things in the water. You do not need to feed fish in a balanced pond, they will do fine on what's available. You can stock it with 29 cent feeder goldfish from Petsmart or down here the County Extension service gives away gambusia (mosquito fish) to anyone with a pond or water feature they want to stock. The fish also fertilize the plants with their poop. Be careful not to put in too many fish.
Balance is the key. Once you get the water balanced, it will generally take care of itself. If you have a big algae bloom going on before you get the pond balanced, you can buy some barley straw that helps clear up the water initially.
