(From Atlas of Oregon Lakes, Johnson et al. 1985). Walton Lake is a small reservoir in the Ochoco Mountains of Central Oregon. It was formed in the 1940s by construction of a 28-foot high, earthfill dam in a marsh near the headwaters of Camp Creek. The reservoir is a contribution to the people of Oregon from the Isaak Walton League of Prineville in honor of their well-known patron. Walton Lake is operated to provide quality public recreation, and the League has been successful in achieving this goal. It attracts anglers in a part of the state where few natural lakes exist. Catches of rainbow trout are good, and the fish are stocked regularly by the Oregon Department of Fish and Wildlife. Swimming is also a popular recreational activity. Motorboats are prohibited. Two Forest Service campgrounds are maintained at the lake for use by visitors.

Water chemistry in Walton Lake is typical of reservoirs in the Blue Mountains. Major ions exist in moderate concentrations; calcium and magnesium in particular are above average for Oregon lakes. As expected, conductivity, pH, and alkalinity are also above average. Macrophytes develop in the shallow areas and emerge above the surface along the shore. The concentration of phosphorus is above average, while water transparency and chlorophyl concentrations are average. Based on these last two characteristics, Walton Lake is classified as mesotrophic, whereas the macrophytic growth and phosphorus concentration indicate a tendency toward a higher trophic status.

The list of plants below includes results of aquatic plant surveys conducted by the Center for Lakes and Reservoirs as well as aquatic invasive plant species detections that have been reported to iMap Invasives: an online, GIS-based invasive species reporting and querying tool.

Plants listed in the table below are categorized as native to Oregon, on the Oregon Department of Agriculture’s (ODA’s) Noxious Weed List, on the Federal Noxious Weed List, or non-native but not listed as noxious. Federal Noxious Weed List plants are plants determined by USDA to be serious threats to U.S. agriculture, irrigation, navigation, public health or the environment (7 C.F.R. 360.200). The ODA Noxious Weed categories are:

ODA Class A - weeds either unknown or with small enough infestations to make eradication or containment possible; targeted for eradication or intensive control.

ODA Class B - regionally abundant weeds (may have limited distribution in some counties); targeted for local/regional control on case-by-case basis.
