One of the James Robb Colorado River State Park units. This description is for the lakes themselves and not the hiking trails around the lakes.
Lightning on the water can be dangerous. Fishermen use the lake constantly; be aware of lines and bobbers, as well as abandoned lines hanging from the power lines on the west side of the southern lake.
The southern lake is where most paddlers launch their canoes/kayaks/stand-up paddleboards. There is a connection to the west of the picnic/launch area by the parking lot to another lake but it is blocked by a path and not navigable. The small bay to the west usually has lots of hanging fishing lines. Heading north across the lake there is another small bay, again on the west side. At the northeast corner of the southern lake is the connection to the northern lake. No major embayments exist in the northern lake.
The lake is not potable. Bring your own.
WARNING! Hiking and outdoor related sports can be dangerous. Be responsible and prepare for the trip. Study the area you are entering and plan accordingly. Dress for the current and unexpected weather changes. Take plenty of water. Never go alone. Make an itinerary with your plan(s), route(s), destination(s) and expected return time. Give your itinerary to trusted family and/or friends.
